ABSTRACT:
A metal cutting tool comprising a cutting insert and a cutting insert holder is described. The insert has a body portion and a head portion. The head portion has an upper rake surface, a front relief flank surface, and a cutting edge defined between the first two. The holder is formed with a pair of jaws which clamp the insert. The first jaw abuts an upper surface of the insert adjacent the rake surface while the second jaw abuts a lower surface of the insert, adjacent to a base edge of the relief flank surface. A portion of this second jaw extends beyond the base edge, forming a projection. The holder is provided with a coolant flow channel having an input adapted to be coupled to a coolant source. A downstream portion of the channel terminates in a coolant flow outlet formed in the projection. The downstream portion and the outlet are arranged such that a coolant outflow from the outlet is directed substantially parallel to the relief surface.
