Abstract: A compact mechanical-type holder with clamping forces, precision and small runout comparative to a heat-shrink holder, and a collet designed for such holder. The collet including an externally tapering collet tapered portion, and flexibility slits opening out to the collet tapered portion. The collet inner peripheral surface includes a recess located between a first cylindrical clamping surface and a second cylindrical clamping surface.

Abstract: A cutting tool having an adapter and a cutting head. The adapter has an adapter clamping portion and a clamping mechanism. The clamping mechanism has an actuator, a central wedge and two flanges slidingly engaged to the central wedge. Each of the two flanges has an elongated rear slanted flange portion configured for clamping the cutting head.

Abstract: A rotary cutting tool includes a tool holder. The tool holder has holder body and an adjustment sleeve circumferentially disposed thereabout. The adjustment sleeve has an at least one sleeve adjustment groove which decreases in distance from a sleeve central axis in a rotational sleeve direction. The tool holder further has a plurality of insert cartridges, each having an insert pocket and at least one cartridge pin. At least one pin is located in a respective sleeve adjustment groove. The tool holder is adjustable between inner and outer adjusted positions by rotating the adjustment sleeve in the rotational sleeve direction. In the outer adjusted position, the insert cartridges are displaced in an outwards adjusted direction so that the insert pockets are radially outwards compared to the inner adjustment position.
