Metal-cutting or milling tool has cylindrical blade fixed to base containing at least three separate blades whose cutting edges are at cutting angles to cutting material determined by distance between front and other blades

摘要

Metal-cutting tool (1) has a cylindrical blade (2,2') fixed on a base part (3) which moves in the cutting direction (S). At least three blades are on the upper surface of the base part,in particular on the front side (6) and/or the circumference of the base part, whose cutting edges (5,5'5'',5''') are attached at a cutting angle (y1,y2,y3,y4) to the material to be cut. At least three of the blades are arranged at uneven distances from one another. The cutting angle of at least some of the blades is determined by the distance between the blades and the front-running blade.
