Abstract
A milling cutting insert has a substantially triangular shape. The cutting insert contains a top side, an underside, and circumferential side surfaces extending between the top side and the underside. Cutting edges are formed at the transition of the circumferential side surfaces to the top side and/or the underside. On the circumferential side surfaces at least two discrete planar abutment surfaces are formed for positioning the cutting insert in a tool holder. The at least two discrete planar abutment surfaces are inclined with respect to each other at an outer angle of between 190° and 220° and the abutment surfaces are spaced from each other with respect to the circumferential direction of the cutting insert.
Claims13
A milling cutting insert, comprising:
- a body having a substantially triangular shape defining a number of indexing positions, said body containing:
- a top side;
- an underside;
- circumferential side surfaces extending between said top side and said underside;
- cutting edges being formed at a transition of said circumferential side surfaces to at least one of said top side or said underside;
- at least two discrete planar abutment surfaces being formed on said circumferential side surfaces for positioning the milling cutting insert in a tool holder, wherein said at least two discrete planar abutment surfaces are inclined with respect to each other at an outer angle of between 190° and 220° and wherein said discrete planar abutment surfaces are spaced from each other with respect to a circumferential direction of the milling cutting insert;
- and
- said discrete planar abutment surfaces being inclined with respect to each other such that when brought into contact to corresponding mating surfaces of the tool holder the milling cutting insert can assume two distinct angular positions for each indexing position.
