Abstract
An improved insert 10 for deep grooving, contouring and cut-off operations is disclosed which is provided with two kinds of chip-breaking projections, three in all. There are two frusto-conical projections 30 near the cutting edge 16 and there is a V-shaped projection 32 behind the frusto-conical projections. The insert expands the range of materials of the work, the groove diameters that can be cut and the feeds and speeds of operations, through improved chip control.
