ABSTRACT:
A single-sided cutting insert preferably for thread chasing, the lower face of which comprises three support surfaces inclining towards the center of the lower face and a recess separating them. The support surfaces are projecting partly around the recess and therefore the cutting insert at insertion against a base surface of a cutting insert site in a tool shank abuts only against the planar base surface in three separated points.
