Abstract
A cutting insert for chipforming machine has a tip face with a cutting edge. Grooves are formed in the top face and extend toward the cutting edge. Chip-deflecting projections extend upwardly from the top face and are situated in spaces formed between adjacent grooves. A jet of cooling fluid is directed toward inner ends of the grooves and travels between the projections and within the grooves toward the cutting edge.
