Bit arrangement for a cutting tool

摘要

The rotary-shaft bit (7) inserted in a bushing (3) fixedly mounted, encloses by means of a hollow-cylindrical extension (9) an annular extension (5) of the bushing (3) and projecting in axial direction of said bushing (3), and in this manner is supported closer to the tip of the bit (8) in order to absorb transverse forces, noting that the front surface (14) of the hollow-cylindrical extension (9) of the bit (7) can be supported on the flange (4) of the bushing (3) (FIG. 1).
