Embodiment Construction

[0027] The adapter 1 shown in FIGS. 1 and 2 comprises four sides 3 , a contact surface 5 and a front surface 7 , with reference to FIG. 5 , the front surface is parallel to the contact surface 5 . A generally triangular-shaped connecting face 9 is provided between adjacent sides 3 , which is slightly curved and positioned near the corners of the adapter 1 .

[0028] Each side 3 has a mounting area 10 , circular in this embodiment and provided with teeth 11 . A first central hole 12 and four threaded anchor holes 13 are arranged symmetrically along the central hole 12 in the above-mentioned installation area 10 , which can be used to provide cooling liquid.

[0029] A cylindrical groove 14 and a groove 15 are provided on the above-mentioned contact surface 5 to facilitate adjoining with the mating surface of the connector. This cylindrical groove 14 extends from the contact face 5 in the direction of the front surface 7, the depth of which is determined by the inner end define...

Abstract

The present invention relates to a tool holder, which is intended to simultaneously carry at least two diametrically arranged heads (20), which carry cutting inserts for chip removing machining, the tool holder comprising an adaptor (1) and a coupling (18). The invention also separately relates to the adaptor (1). Characteristic of the tool holder according to the present invention is that the adaptor (1) has at least two diametrically opposite side surfaces (3), which diverge in the direction from the coupling (18), that the side surfaces (3) have members (10) in order to replaceably receive a tool head (20), and that a line (L) which is situated in a first basal plane (BP1) and in one of the side surfaces (3) forms an angle ( alpha ) in the interval 1 DEG -15 DEG to a longitudinal centre line C-C for the tool holder.

Description

technical field [0001] The invention relates to a tool holder, which can carry at least two radially opposite cutter heads at the same time, and the cutter head can carry cutting inserts for chip removal processing. The tool holder includes an adapter and a connecting piece. The invention also relates solely to an adapter comprised in the above-mentioned tool holder. Background technique [0002] From US-A-6 244 780 is known an embodiment of a knife having three serration faces, two of which are preferably parallel to each other, and the third face has an extension perpendicular to the two parallel planes mentioned above. All three faces have elements for receiving the cutter head, said members being constituted by holes accommodating the pull rods of said cutter head. However, the tool holder according to US-A-6 244 780 cannot carry several cutting heads at the same time. Contents of the invention [0003] A main object of the present invention is to provide a tool hold...
