Abstract
A turning toolholder includes a shank, a club head, and a clamp and a clamp screw for clamping a cutting insert. The club head includes a clamp coolant supply hole in fluid communication, a flank coolant supply hole and an auxiliary rake coolant supply hole, all in fluid communication with the main coolant supply hole. Coolant is supplied through a rake coolant exit opening formed in the forward nose portion of the clamp to direct coolant to the top rake surface of the cutting insert, and coolant is supplied through a flank coolant exit opening located below the insert-receiving pocket to provide coolant to the side flank surfaces of the cutting insert. In addition, an auxiliary rake coolant supply housing formed on a top surface of the club head supplies additional coolant to the top rake surface of the cutting insert during high heat applications.
