The cutting region includes a pair of chip deflectors and a plurality of coolant directing elements separating a plurality of coolant channels configured in at least one hub and spoke arrangement that directs coolant radially outward from the central, longitudinal axis, A, to the entire cutting edge of the cutting insert.

Cutting assembly with cutting insert having enhanced coolant delivery

A toolholder at least one cutting insert mounted within a pocket about the peripheral wall of the cutter body. The body includes a pocket having an angled retention ledge which provides acts, in conjunction with a fastener, to securely retain an insert mounted therein. The insert has an angled edge which conforms with and works in conjunction with the toolholder pocket.
