High chipbreaker wall
By lowering the cutting edge height, high and broad chipbreaker wall can
be formed near the corner point.
Can restrict thin chips formed in finishing.
Even at the allowable highest feed, chips do not surmount the
chipbreaker wall.

Stable insert seating
Sufficient boss face is formed along the insert outline.
Improved seating stability obtained with the whole of the insert.

Inclination
By inclining the cutting edge from the boundary between the corner radius
and straight cutting edge, the side rake angle is increased in the direction
of the arrow.
In profiling, chips are forced to curl sideward and be broken.
In undercutting, chips are evacuated smoothly.

Dimple structure
A dimple is formed near the corner point on the rake face.
Can reduce the contacting area between chips and the rake face, suppressing the occurrence of thermal cracks.
