チツプ。[Claims for Utility Model Registration] A main cutting edge 5 directly involved in parting and grooving, and side cutting edges 6 located on both sides of the main cutting edge 5 are formed, and these main cutting edges The rake face surrounded by the cutting edge 5 and the side cutting edge 6 has a
Chip breaker groove 4 is formed so that a narrow land 3 is formed on the main cutting edge 5 side and a band-like surface 2 is formed on the side edge 6 side.
In the tip for parting and grooving, the band-like surface 2 has a first inclined surface 2a forming an upward slope angle θ 1 from the main cutting edge 5 side including the land 3. By providing a second inclined surface 2b that forms an inclination angle θ 2 downward from the first inclined surface 2a, the second inclined surface 2b has a substantially angular shape in side view, and the inclination angle θ 1 is θ 1 = 5
° to 15°, the inclination angle θ 2 is set within the range of θ 2 = 1° to 12°, and the horizontal length A from the main cutting edge 5 to the top of the first inclined surface 2a is A = 0. .5
A chip for parting and grooving, characterized in that the chip is set to be smaller than the horizontal length L of the chip breaker groove 4 including the width of the land 3, within the range of ~2.0 mm.
