    摘要： A single-sided cutting insert (10) preferably for thread chasing, the lowerface (12) of which comprises three support surfaces (23-25) inclining towards the center of the lower face (12) and a recess (26) separating them. The support surfaces (23-25) are projecting partly around the recess (26) and therefore the cutting insert (10) at insertion against a base surface (27) of a cutting insert site in a tool shank (28) abuts only against the planar base surface in three separated points (29).
