FIELD: material processing.
SUBSTANCE: group of inventions relates to material processing by cutting; it can be used when drilling holes. Drilling tool (10) contains insert (15) that has at least one cutting edge (26) formed at the intersection of adjacent front surface (25) and rear surface (24). Cutting edge (26) has a length oriented radially on the tool, and single chip breaker (28) made in the form of a convex protrusion or recess at front surface (25), and continuing from cutting edge (26). At the intersection of front surface (25) and rear surface (24), chamfer (29) is made, located at chip breaker (28) and formed relatively to the profile of cutting edge (26) on one or both sides of chip breaker (28).
EFFECT: chip crushing during drilling is facilitated, productivity is increased.
