摘要

The cutter plate is for a single-cutter reamer, having a rectangular body with a main cutting edge, onto which an auxiliary one joins. A clearance face slopes downwards from the edges, for which a chip face is provided, enclosed by a guide step. The step (25) intersects the auxiliary cutting edge (NS). It can be inclined to the lengthwise axis (A) of the plate at between 10 and 80 deg. ADVANTAGE - Precision-machining at high speed without tool chatter.
