Patent ID: 7044695

Claim:
A milling tool, comprising: an elongated bar having a longitudinal rotational axis, a shank at one end thereof, a cutter head forming an integral extension of the shank at the opposite end of the bar, and wherein the cutter head includes a first clamping structure having a first clamping face; the first clamping structure having a threaded fastener-receiving opening formed along an axis perpendicular to the first clamping face; a second clamping structure removably mounted on the first clamping structure to define an insert-receiving slot having opposed parallel insert clamping faces; the second clamping structure having a fastener-receiving opening aligned with the threaded fastener-receiving opening of the first clamping structure; a fastener disposed in the aligned fastener-receiving openings of the first clamping structure and the second clamping structure to prevent separation thereof, the first clamping structure having a threaded through-hole for receiving a camming screw; the second clamping structure having a through-hole, aligned with the threaded through-hole of the first clamping structure; a cutting insert disposed in the insert-receiving slot, the cutting insert having a fastener-receiving through-hole; a camming screw disposed in the aligned through holes of the first clamping structure, the second clamping structure and the cutting insert to retain the cutting insert in said insert-receiving slot for a metal cutting motion; the camming screw having a camming section with a diameter less than the diameter of the insert hole such that as the camming screw is rotated, the camming section biases the insert toward a seated position in the slot; and one of said clamping structures having a ridge and the other of said clamping structures having a channel, the channel receiving the ridge to prevent movement of the second clamping structure with respect to the first clamping structure.
