Japanese Patent JP2000505361
Kind Code:
A
Abstract:
An indexable cutting insert for metal machining comprises a rake surface (5), a bottom surface (6) and side surfaces (7) that extend between said two surfaces, cutting edges (10) being formed at the transitions between the side surfaces and the rake surface. Along the cutting edges on the rake surface are elongated primary lands (11) and inside these chip-breaking depressions (9). In order to make possible a grinding of the cutting edges on the rake surface, it is provided with a land area (12) to be ground inside the chip breaker (9), so that the total grinding area of the rake surface becomes about as large as the total grinding area of the bottom surface.
