Claim Text:
1. A clamp to secure a cutting insert to a tool holder to remove material chips from a work piece, the clamp comprising: a proximal portion with a toe, a distal portion with a heel, a first lateral side, a second later side that is generally opposite the first lateral side, and an aperture therebetween to receive a fastener through the body to engage a hole in the tool holder, and a coolant passage including an inlet in the distal portion of the clamp to receive a flow of coolant from a coolant supply conduit, an outlet in a proximal portion of the clamp to direct a stream of coolant to impinge on a cutting interface between the work piece and a cutting edge of the cutting insert, and an intermediate channel passing laterally to the aperture; wherein the toe on the proximal portion of the clamp engages a receiving groove on the cutting insert to secure the cutting insert in position on the tool holder and against dislodgment from the forces applied by engagement of the cutting insert with the work piece; wherein the heel on the distal portion of the clamp engages a receiving détente on the tool holder to position the clamp relative to the tool holder; wherein the stream of coolant impinging on the work piece lubricates the cutting interface to reduce the heat generated at the cutting interface; wherein the inlet to the coolant passage is formed in the distal portion of the clamp intermediate a first lateral side of the claim and a generally opposite second lateral side of the clamp; and wherein an intermediate portion of the coolant passage passes between the first lateral side and the aperture of the clamp.
