Description

[0001] The present invention relates to a hinge drilling jig for producing a drilling pattern for hinges in a furniture panel, comprising: - at least one basic shape, - at least one cylinder head drill for producing a cylindrical recess to receive a hinge cup in the furniture panel, - at least two clamping devices spaced apart from each other for clamping the furniture panel relative to the base body, - at least one stop device for placing the base body against an end face of the furniture panel.

[0002] Such a hinge drilling jig has been marketed by the applicant for many years under the name "ECODRILL". It is an easy-to-use and portable handheld device for precisely drilling holes in furniture components. A specific hinge drilling pattern can be set, allowing the cylindrical drill bit to be inserted into the furniture component at a predetermined location using a hand drill to create a cylindrical hole for a hinge cup. In addition to the central cylindrical drill bit, two lateral dowel drill bits are provided. These have a smaller diameter than the cylindrical drill bit and are used to create further cylindrical holes for the expansion dowel of the furniture hinge.

[0003] One disadvantage of the known design is that the two clamping devices for securing the furniture panel must be operated separately. This can lead to the problem of the two clamping devices being adjusted unevenly, resulting in different clamping forces being exerted on the furniture panel. This can cause the furniture panel to move relative to the base of the hinge drilling jig during the drilling process, ultimately resulting in the hole being drilled in the wrong location. Furthermore, two separate stops are provided for contact with one end face of the furniture panel, allowing the distance of the cylindrical drill bit relative to the end face to be adjusted.Here too, the problem can arise that the two stops are set differently due to carelessness or lack of knowledge, so that in this case as well there is a risk of drilling incorrectly. Such incorrect drilling can ultimately lead to the furniture panels, which often have a high-quality and expensive decorative coating, becoming unusable and having to be disposed of.

[0004] The object of the present invention is to provide a hinge drilling jig of the type mentioned at the outset, avoiding the disadvantages discussed above.

[0005] This is achieved according to the invention by the features of claim 1. Further advantageous embodiments of the present invention are defined in the dependent claims.

[0006] According to the invention, a clamping lever is provided by which the at least two clamping devices can be actuated together and / or wherein the at least one stop device is arranged in a central area of ​​the at least one base body between the at least two clamping devices.

[0007] In other words, a clamping lever is provided by which the at least two spaced-apart clamping devices for clamping the furniture panel can be moved simultaneously between a clamping position and a release position. This prevents different settings and / or incorrect operation of the clamping devices.

[0008] Alternatively or additionally, at least one stop device is arranged in a central area of ​​the base body between the two clamping devices. This measure also prevents the two different stops from being set differently.

[0009] The stop device can, for example, have a movable, preferably linearly displaceable and / or continuously adjustable, stop plate for contact with the furniture panel.

[0010] For example, a rotatable adjustment wheel can be provided to set the position of the stop plate, whereby the position of the stop plate relative to the base body can be adjusted by rotating the adjustment wheel.

[0011] Instead of the rotatable adjustment wheel, the stop plate can also be moved via at least one elongated hole, whereby a preset position of the stop plate can be locked by a locking screw.

[0012] Further details and advantages of the present invention will become apparent from the following description of the figures. Fig. 1a, Fig. Figure 1b shows a piece of furniture with a furniture body and a furniture part that can be moved relative to the furniture body, as well as the movable furniture part in perspective views. Fig. 2a, Fig. Figure 2b shows an embodiment of a hinge drilling jig in two different views with the clamping lever in a clamping position and in a release position. Fig. 3a, Fig. Figure 3b shows the hinge drilling jig in a front view and in a top view, with the clamping lever in a clamping position. Fig. 4a, Fig. Figure 4b shows the hinge drilling jig with the clamping lever in a released position and in a clamped position. Fig. 5a, Fig. Figure 5b shows the hinge drilling jig with the clamping lever in a released position and in a clamped position in partially broken views. Fig. 6a, Fig. Figure 6b shows a cross-section of the hinge drilling jig with the clamping lever in the released position and a side view of the hinge drilling jig with the clamping lever in the clamped position. Fig. Figures 7a-7c show different views of a cylinder head drill with a chip breaker. Fig. 8a, Fig. Figure 8b shows the cylinder head drill in its assembly position in two different views.

[0013] Fig. Figure 1a shows a piece of furniture 1 with a furniture carcass 2 and a furniture part 3 in the form of a furniture panel 3a, which is movable relative to the furniture carcass 2. The movable furniture part 3 is pivotally mounted relative to the furniture carcass 2 by means of two or more hinges 4.

[0014] The hinges 4 each have a hinge arm 5 to be attached to the furniture body 2 and a hinge cup 6 to be attached to the movable furniture part 3. The hinge cup 6 is pivotally connected to the hinge arm 5, for example via at least one joint lever. The hinge cup 6 is attached to the movable furniture part 3 via at least one mounting flange 9.

[0015] Fig. Figure 1b shows the movable furniture part 3 in the form of the furniture panel 3a in a perspective view. A cylindrical recess 7, preferably with a diameter of 35 mm, is provided for attaching the hinge cup 6 to the furniture panel 3a, wherein the hinge cup 6, in a mounted state, is received at least partially within the cylindrical recess 7 of the furniture panel 3a.

[0016] In addition to the cylindrical recess 7, two lateral dowel bores 8a, 8b are provided, which are designed to receive an expandable dowel (not shown) of the hinge 4. Such dowels can be arranged on the underside of the mounting flange 9 of the hinge 4.

[0017] The cylindrical recess 7 for receiving the hinge cup 6 and the dowel bores 8a, 8b for receiving dowels of the hinge 4 are each arranged at a predetermined distance relative to an end face 19a and relative to side surfaces 19b, 19c of the furniture panel 3a.

[0018] However, the two lateral dowel holes 8a, 8b are not absolutely necessary, because the mounting flange 9 of the hinge 4 can also be attached to the furniture panel 3a using conventional screws.

[0019] The cylindrical recess 7 for receiving the hinge cup 6 and the dowel holes 8a, 8b for receiving dowels of the hinge 4 can be drilled using a hinge drilling jig 10 which will be described later ( Fig. 2a) to produce a drilling pattern for the hinges 4 in the furniture panel 3a.

[0020] Fig. Figure 2a shows a possible embodiment of a hinge drilling jig 10 in a perspective view.

[0021] The hinge drilling jig 10 includes - at least one basic body 11, - at least one cylinder head drill 12 for producing a cylindrical recess 7 for receiving a hinge cup 6 in the furniture panel 3a, - at least two spaced-apart clamping devices 16a, 16b for clamping the furniture panel 3a relative to the base body 11, - at least one stop device 28 ( Fig. 2b) for the attachment of the base body 11 to an end face 19a ( Fig. 1b) the furniture panel 3a, - a clamping lever 15 by which the at least two clamping devices 16a, 16b can be actuated together and / or wherein the at least one stop device 28 is arranged in a central area of ​​the at least one base body 11 between the at least two clamping devices 16a, 16b.

[0022] The clamping lever 15 allows the two clamping devices 16a, 16b to be moved together between a clamping position and a release position, thus preventing incorrect operation of the clamping devices 16a, 16b.

[0023] The clamping devices 16a, 16b can each have a locking element 17a, 17b, preferably rotatably mounted, by which the furniture panel 3a can be pre-clamped relative to the base body 11.

[0024] For the final fixing of the furniture panel 3a relative to the base body 11, a movable, preferably pivotable, clamping lever 15 is provided, wherein by actuating the clamping lever 15 via the clamping devices 16a, 16b a substantially uniform clamping force can be exerted on the furniture panel 3a.

[0025] The cylinder head drill 12 is rotatable via a rotary drive 18a, wherein the cylinder head drill 12 is rotated by means of a hand drill 31 by means of a hand drill 31 ( Fig. 4a, Fig. 4b) is propellable.

[0026] In addition to the cylinder head drill 12, two further dowel drills 20 are provided, which are used for drilling the two dowel holes 8a, 8b ( Fig. 1b) are provided. The dowel holes 8a, 8b are provided for receiving dowels of the hinge 4.

[0027] However, as already mentioned, the production of the dowel holes 8a, 8b can be omitted, since screws can also be provided for fastening the mounting flange 9 of the hinge 4.

[0028] The two dowel drills 20 each also have a rotary drive 18b, 18c, wherein the dowel drills 20 can be set in rotation by driving the rotary drives 18b, 18c by means of a hand drill 31.

[0029] If, however, instead of the two dowel holes 8a, 8b, only a center mark in the furniture panel 3a is to be made for inserting a screw, then (not shown here) additional parts in the form of spacers are provided. The spacers, which are preferably designed as C-clips, can be attached to the shaft below the rotary drives 18b, 18c. In this way, when driven by the hand drill 31, the rotary drives 18b, 18c can only be moved a small portion of the way towards the base body 11, so that essentially only the centering tip of the dowel drill bit 20 can be inserted into the furniture panel 3a to create the mark.

[0030] The clamping lever 15 is mounted to allow movement between a clamping position and a release position. Fig. Figure 2a shows the clamping position of the clamping lever 15, in which access to at least one rotary drive 18a, 18b, 18c, preferably to all provided rotary drives 18a, 18b, 18c, of the hinge drilling jig 10 is possible.

[0031] If, however, the clamping lever 15 is in a released position, access to a rotary drive 18a, 18b, 18c, preferably to all rotary drives 18a, 18b, 18c, is blocked. This represents a significant safety aspect because the rotary drives 18a, 18b, 18c are only accessible by means of a hand drill 31 when the furniture panel 3a is properly fixed relative to the base body 11 of the hinge drilling jig 10.

[0032] At least one stop 21a is provided, which is movably mounted on the hinged drilling jig 10, preferably foldable, and / or at least one scale 22a is provided to indicate a distance of the cylinder head drill 12 relative to a side surface 19b, 19c ( Fig. 1b) of the furniture panel 3a. The position of the stop 21a along the scale 22a can be fixed by a clamping screw 26a.

[0033] Extraction of the chip material is possible through at least one extraction opening 27. Preferably, the at least one extraction opening 27 extends obliquely towards the cylinder head drill 12 and / or has at least one O-ring for clamping a suction nozzle.

[0034] Fig. Figure 2b shows the hinge drilling jig 10 in a top view, with the pivotable clamping lever 15 in a released position. In the released position of the clamping lever 15, the rotary drives 18a, 18b, 18c cannot be operated by the hand drill 31 because the clamping lever 15 blocks access to the rotary drives 18a, 18b, 18c.

[0035] The hinge drilling jig 10 can have at least one handle 23, preferably in the form of a U-shaped handle, for handling or transporting the hinge drilling jig 10.

[0036] The at least one stop device 28 for positioning the base body 11 against an end face 19a ( Fig. 1b) The furniture panel 3a is arranged in a central area of ​​the at least one base body 11 between the at least two clamping devices 16a, 16b.

[0037] The stop device 28 can have a movable, preferably linearly displaceable and / or continuously adjustable, stop plate 28a for resting against the furniture panel 3a.

[0038] In the illustrated embodiment, the position of the stop plate 28a can be adjusted via at least one elongated hole 28b and / or fixed after adjustment by a rotatably mounted knurled screw 28c.

[0039] Of course, other options can also be provided for the, preferably stepless, adjustment of the stop plate 28a, for example at least a self-locking adjustment wheel, a self-locking eccentric or a self-locking worm gear.

[0040] The stop device 28 can have at least one window 24 which allows a view through to a marking 25 arranged or arrangable on the furniture panel 3a. The window 24 is relatively large so that the marking 25 is clearly visible.

[0041] Fig. Figure 3a shows the hinge drilling jig 10 in a front view, showing the cylinder head drill 12, the chip breaker 14 and the two side dowel drills 20.

[0042] It can be seen that the at least one cylinder head drill 12 and at least one dowel drill 20, preferably both dowel drills 20, are offset from each other in the vertical direction by an amount X, preferably by about 3 mm.

[0043] The offset arrangement between the cylinder head drill 12 and the side dowel drills 20 reduces the risk of long chips becoming jammed and thus of scratching a decorative surface of the furniture panel 3a.

[0044] The cylinder head drill 12 and the dowel drills 20 can each be driven separately by a rotary drive 18a, 18b, 18c. A hand drill 31 and a screwdriver bit 30 that engages with the rotary drives 18a, 18b, 18c are required to drive the rotary drives 18a, 18b, 18c. Fig. 4a, Fig. 4b) required. The screw bit 30 can, for example, be designed as a Phillips screw bit, a Pozidriv bit or a Torx bit.

[0045] Fig. Figure 3b shows the hinge drilling jig 10 in a top view, with the furniture panel 3a clamped in place by the pivot lever 15. The pivot lever 15 is thus in a clamping position, allowing access to the rotary drives 18a, 18b, 18c with a hand drill 31. In the released position of the clamping lever 15, however, access to the rotary drives 18a, 18b, 18c is blocked.

[0046] The hinge drilling jig 10 also features the following: Fig. 2a shown stop 21a at least one further stop 21b, wherein the stop 21a is for attachment to a first side surface 19b ( Fig. 1b) the furniture panel 3a and the further stop 21b for attachment to the second side surface 19c of the furniture panel 3a is provided.

[0047] The position of the further stop 21b along the scale 22b can be fixed by a locking screw 26b.

[0048] The two stops 21a, 21b can be folded in relative to the base body 11 of the hinge drilling jig 10 when not in use.

[0049] The distance of the cylinder head drill 12 relative to the end face 19a of the furniture panel 3a is adjustable by the stop device 28. The stop device 28 comprises a linearly displaceable and / or continuously adjustable stop plate 28a, which is designed to rest against the end face 19a of the furniture panel 3a.

[0050] To adjust the stop plate 28a, the knurled screw 28c is loosened and the stop plate 28a is moved to the desired position via the at least one elongated hole 28b. The preset position of the stop plate 28a can then be fixed again using the knurled screw 28c.

[0051] For reading the position of the stop device 28, at least two scales 29a, 29b are provided, wherein a first of the two scales 29a indicates a distance to a center of the cylindrical recess 7 to be produced and a second of the two scales 29b indicates a distance to an edge of the cylindrical recess 7 to be produced.

[0052] Providing two scales 29a and 29b is advantageous because, in connection with a cabinet configurator or a product catalog, two different dimensions exist for drilling the cylindrical recess 7, which can be displayed using the two scales 29a and 29b. Of course, only one of the two scales 29a or 29b can be provided.

[0053] According to one embodiment, it can be provided that the at least one base body 11 has at least one receiving compartment 50 for receiving a drilling jig 51, preferably designed as a mounting bracket, for a hinge arm 5 of a hinge 4.

[0054] At least one magnet 52 can be used to detachably fasten the drilling jig 51 in the receiving compartment 50. The drilling jig 51, designed as an additional part, is intended for creating a drilling pattern for the hinge arm 5 on the furniture body 2.

[0055] Fig. Figure 4a shows the hinge drilling jig 10 with the base body 11, the handle 23 arranged on the base body 11 and the clamping lever 15 which can be pivoted relative to the base body 11.

[0056] In Fig. 4a The clamping lever 15 is in a released position in which the clamping lever 15 at least partially covers the rotary drive 18a of the cylinder head drill 12, thus blocking access to the rotary drive 18a. Fig. 4a, therefore, it is not possible to operate the rotary drive 18a using the screw bit 30 of the hand drill 31.

[0057] In Fig. In 4b, the clamping lever 15 is in a clamping position in which the rotary drive 18a of the cylinder head drill 12 is freely accessible for the screw bit 30 of the hand drill 31. In the clamping position of the clamping lever 15, the cylindrical recess 7 in the furniture panel 3a can therefore be drilled at a predetermined location by driving the rotary drive 18a using the hand drill 31.

[0058] Fig. Figure 5a shows a partially cutaway view of the hinge drilling jig 10 with the clamping lever 15 in the released position. The clamping devices 16a and 16b each have an axis 33 which is guided with play in an elongated hole 32.

[0059] The clamping lever 15 is rotated about a pivot axis 37 ( Fig. 6a) rotatably mounted on the base body 11 and / or has at least one eccentric surface 34 arranged on the clamping lever 15 for moving the at least two clamping devices 16a, 16b relative to the base body 11.

[0060] The axis of rotation 37 of the clamping lever 15 runs essentially perpendicular to the axis of rotation 39 ( Fig. 7a-7c) of the cylinder head drill 12.

[0061] The axle 33 is connected to a clamping bracket 35 ( Fig. 6a, Fig. 6b) connected, which is attached to a subside 19d ( Fig. 6a, Fig. 6b) is formed of the furniture panel 3a.

[0062] At least one clamping device 16a, 16b, preferably both clamping devices 16a, 16b, has or have at least one energy storage device 38 ( Fig. 6b) which applies a force to the clamping bracket 35 in the direction of a position that clamps the furniture panel 3a.

[0063] The pre-clamping position of the axis 33 connected to the clamping bracket 35 can be locked by the rotatable locking elements 17a, 17b.

[0064] However, the locking elements 17a and 17b only need to establish the pre-clamping position once. Once the pre-clamping position relative to the material thickness of the furniture panel 3a has been set, clamping and releasing the furniture panel 3a is achieved only by actuating the clamping lever 15.

[0065] Fig. Figure 5b shows a partially broken view of the hinge drilling jig 10 with the clamping lever 15 in the clamping position.

[0066] The axis 33 is moved by a pivoting movement of the clamping lever 15 starting from the released position according to Fig. 5a into the clamping position according to Fig. 5b movable, wherein the axis 33 is located at one end of the elongated hole 32 and wherein the clamping position of the clamping lever 15 is determined by the eccentric surface 34.

[0067] Fig. Figure 6a shows a cross-section of the hinge drilling jig 10 with the clamping lever 15 in the released position, in which the rotary drive 18a of the cylinder head drill 12 is not accessible for operation by means of the hand drill 31.

[0068] The clamping device 16a, 16b has at least one clamping bracket 35 for contact with an underside 19d of the furniture panel 3a. By means of at least one energy storage device 38 ( Fig. 6b) The clamping bracket 35 is subjected to a force in the direction of a position that clamps the furniture panel 3a. The at least one force storage device 38 can, for example, be designed as a tension spring or as a compression spring.

[0069] By applying force to a handle 36 against a force of the energy storage device 38, the pre-clamping position of the clamping bracket 35 can be released.

[0070] In the illustrated embodiment, the clamping position of the clamping bracket 35 can be released by pressing the handle 36 in a downward direction (i.e., in a direction parallel to the axis of rotation 39 of the cylinder head drill 12). This moves the clamping bracket 35 downwards, allowing the furniture panel 3a and the hinge drilling jig 10 to be aligned relative to each other or separated from each other.

[0071] Once the furniture panel 3a is correctly aligned relative to the hinge drilling jig 10, the pre-clamping position of the furniture panel 3a can be pre-fixed by the clamping element 17a, 17b of the clamping device 16a, 16b.

[0072] At least one cylinder head drill 12 has a distance of more than 3 mm from a zero plane in its zero position, in which an untreated surface 19e of the furniture panel 3a can be arranged. In this way, the risk of jamming of long chips is reduced.

[0073] Fig. Figure 6b shows a side view of the hinge drilling jig 10 with the clamping lever 15 in the clamping position in which access to the rotary drive 18a of the cylinder head drill 12 is possible.

[0074] Through the rotation around the axis 37 ( Fig. 6a) The pre-clamping position can be permanently fixed by means of the pivoting clamping lever 15, so that the cylindrical recess 7 can be drilled by driving the rotary drive 18a using the hand drill 31.

[0075] The power storage device 38 is shown schematically, which applies a force to the clamping bracket 35 in the direction of a position that clamps the furniture panel 3a.

[0076] Fig. Figures 7a-7c show different views of a cylinder head drill 12 for a hinge drilling jig 10 for producing a drilling pattern for hinges 4 in a furniture panel 3a.

[0077] Fig. Figure 7a shows a view of a cylinder head drill 12 and a chip breaker 14 arranged or arrangable on the cylinder head drill 12.

[0078] The cylinder head drill 12 includes: - at least one shaft 40 rotatable about a pivot axis 39 for clamping the cylinder head drill 12 into the hinge drilling jig 10, - at least one cutting head 41 with at least one end-face main cutting edge 13 for producing a cylindrical recess 7 in the furniture panel 3a, - at least one chip breaker 14 for crushing the resulting chip material, wherein the at least one chip breaker 14 is at least partially conical in order to push the chip material to be crushed from the axis of rotation 39 in a direction away from the axis of rotation 39.

[0079] The conical or frustoconical shape of the chip breaker 14 is designed to transport the resulting chip material obliquely outwards from the axis of rotation 39 when drilling the cylindrical recess 7, whereby the displaced chip material can be crushed by several cutting edges 43 of the rotating chip breaker 14.

[0080] According to one embodiment, the at least one chip breaker 14 is essentially crown-shaped.

[0081] The at least one chipbreaker 14 can have at least one, preferably circular, opening 44 for receiving the shaft 40.

[0082] According to one embodiment, the at least one chip breaker 14 is designed as a component separate from the cylinder head drill 12, which is firmly connected to the cylinder head drill 12, preferably by gluing, welding or pressing.

[0083] Alternatively, the chipbreaker 14 and the cylinder head drill 12 can be detachably connected to each other via at least one positive-locking connection. In the connected state, the chipbreaker 14 is rotationally fixed to the cylinder head drill 12 via the positive-locking connection. In the event of damage or wear, the chipbreaker 14 can be easily replaced.

[0084] Alternatively, it is possible that at least one chip breaker 14 is formed in one piece together with the cylinder head drill 12.

[0085] The at least one chip breaker 14 can have at least one, preferably trough-shaped and / or conically tapered, discharge channel 45 for removing chip material.

[0086] Preferably several, preferably trough-shaped and / or conically tapered, discharge channels 45 are provided for the removal of chip material.

[0087] In the illustrated embodiment, the discharge channels 45 are essentially semi-elliptical in a top view and / or evenly distributed over the conical or frustoconical circumferential surface of the at least one chip breaker 14.

[0088] Between two adjacent discharge channels 45, at least one cutting surface 43 can be arranged for crushing the chip material.

[0089] In the illustrated embodiment, the at least one chip breaker 14 has twelve discharge channels 45 and / or twelve cutting surfaces 43.

[0090] According to one possible embodiment, the discharge channels 45 can be conical, preferably within an angular range between 20° and 30°.

[0091] The cylinder head drill 12 can have at least one, preferably lateral and / or web-shaped, cutting surface 46 for crushing the chip material and / or at least one centering tip 42 for centering the cylinder head drill 12 on the furniture panel 3a.

[0092] The longitudinal direction of the cutting surface 46 can essentially run parallel to the axis of rotation 39 of the cylinder head drill 12.

[0093] In the illustrated embodiment, the cylinder head drill 12 has, in addition to at least one main cutting edge 13, at least one further, preferably pointed, end-face cutting edge 47.

[0094] Fig. Figure 7b shows the chip breaker 14 arranged on the cylinder head drill 12, wherein the chip breaker 14 is arranged behind the cutting head 41 in a feed direction of the cylinder head drill 12.

[0095] Fig. Figure 7c shows the chip breaker 14 arranged on the cylinder head drill 12 in a cross-section.

[0096] According to a preferred embodiment, the largest diameter of the at least one chip breaker 14 is smaller than the smallest diameter of the at least one cutting head 41. This ensures that the removal of material from the furniture panel 3a is carried out, preferably exclusively, by the cutting head 41 and not by the chip breaker 14.

[0097] The conical or frustoconical chipbreaker 14 has two base surfaces of different sizes spaced apart from each other along the axis of rotation 39, with a larger base surface of the chipbreaker 14 having a greater distance to the cutting head 41 than the smaller base surface.

[0098] At least one chip breaker 14 is arranged adjacent to the cutting head 41 on the shaft 40 and / or is mounted on the cutting head 41.

[0099] The cone angle of the at least one chip breaker 14 can be between 50° and 90°, preferably between 70° and 80°.

[0100] The length of the at least one chipbreaker 14, measured in the direction of the axis of rotation 39, can be less than or equal to the greatest possible length of the cutting head 41.

[0101] Fig. Figure 8a shows a cross-section of the cylinder head drill 12 in an assembly position. The cutting head 41 can have a centering tip 42, at least one end-face main cutting edge 13 and an end-face cutting edge 47.

[0102] The conical or frustoconical cutting breaker 14 is arranged behind the cutting head 41 in the feed direction of the cylinder head drill 12 and has several discharge channels 45 distributed over the outer surface of the cutting breaker 14 for removing the chip material and / or several cutting surfaces 46 distributed over the conical outer surface of the cutting breaker 14 for crushing the chip material.

[0103] The two dowel drills 20 create the dowel holes 8a, 8b ( Fig. 1b) can be manufactured to accommodate dowels of hinge 4.

[0104] Fig.Figure 8b shows the cylinder head drill 12 with the chip breaker 14 in a bottom view. The base body 11 of the hinge drill jig 10 has at least one counter surface 48 and / or constriction 49, which is arranged adjacent to the cylinder head drill 12 and against which the chip material to be crushed can be forced via the at least one chip breaker 14.

[0105] The chip breaker 14 allows the resulting chip material to be broken down into smaller pieces, thus reducing the risk of long chips becoming jammed between the cylinder head drill 12, the dowel drills 20 and the furniture panel 3a, and therefore reducing the risk of damage to a surface 19e of the furniture panel 3a.
