Problems solved by technology

These clamping forces can be exceeded under high machining forces caused by high-strength workpiece materials or the gradual wear of the cutting edge of the cutting insert, or tool vibrations during drilling, or tool withdrawal from the produced hole, and the cutting insert Can be disengaged from its position, which limits the scope of application of the tool concept

Embodiment Construction

[0061] about Figures 1 to 16 , shows two embodiments of a drilling tool and an associated replaceable cutting disc according to the invention.

[0062] The first embodiment ( figure 1 and 2 ) shows multi-part tools that are mainly used for greater drilling depths in addition to guide strips. The second embodiment ( image 3 , Figure 4 , Figure 14 and Figure 15 ) shows a one-piece tool mainly used for smaller drilling depths.

[0063] The form-locking connection between the drill bit and the replaceable cutting disc is always the same in both embodiments.

[0064] figure 1 A drilling tool 1 according to the invention is shown in an isometric view, which tool consists of several parts. The drilling tool 1 comprises a clamping end 3 , a shank 5 and a drill bit 7 .

[0065] The figure relates to a constructed drilling tool in which the clamping end 3 , the shank 5 and the drill bit 7 consist of different parts and are connected to one another, for example by welding....

Abstract

Described are a drilling tool (1) and a replaceable cutting disk (13) which allow the replaceable cutting disk to be positioned with high accuracy and in a form-locking manner in the drilling tool. Atthe same time, a cutting disk can be replaced more easily.

Description

technical field [0001] The present invention relates to a drilling tool with replaceable cutting discs for machining processes on drills, lathes, machining centers and other machine tool tools and to a replaceable cutting disc therefor. Background technique [0002] Drills with replaceable cutting discs are available in a variety of designs. They are also known as replaceable disc drills. [0003] A replaceable disc drill includes a clamping end, a substantially cylindrical shank and a drill bit. The clamping end is at the rear end and the drill bit is at the front end. A handle is arranged between them. A longitudinal axis, which corresponds to the axis of rotation during drilling, extends from the clamping end to the drill bit. A socket for a replaceable cutting disc is formed at the front end (bit). The clamping end is the generally cylindrical receiving shaft used to attach the drilling tool to the machine spindle. [0004] Finally, the cutting inserts (replaceable...
