Abstract: A tangential cutting insert has a body with an operative front surface associated with upper and lower main cutting edges, side auxiliary cutting edges and corner cutting edges therebetween. All cutting edged have rake surfaces formed at the front surface and extending from their associated cutting edges in an inward direction of the cutting insert. The cutting insert has an imaginary reference plane passing through extremities of the cutting corner edges thereof. Each of the main cutting edges extends from its associated comer edges in an inward direction of the cutting insert away from the reference plane.

Abstract: A cutting tool including a cutting tool body having a peripheral surface formed with a plurality of recesses each adapted to receive an insert receiving cartridge. Each cartridge has transversely directed first and second side surfaces with an imaginary bisector plane therebetween defining a leading cartridge portion associated with the side surface and a trailing cartridge portion associated with the side surface. The leading cartridge portion includes a chip clearance wall and the trailing cartridge portion includes an insert receiving pocket with a cutting insert having a peripheral cutting edge which protrudes in respect of the peripheral surface. Each recess has leading and trailing surfaces converging away from the peripheral surface and against which abut the side surfaces of its associated cartridge received therein. Both the side surfaces are co-extensive with the leading and trailing surfaces.

Abstract: A metal cutting tool comprising a tool holder formed with at least one insert receiving pocket and a replaceable shim formed by powder pressing and sintering and having an elongated rib formed integrally therewith along an edge thereof and being releasably retainable in an elongated recess formed along an edge of said pocket.

Abstract: A tool assembly comprises first and second tool assembly units formed with interfitting male and female coupling members coaxially coupled together so as to have a common longitudinal axis, whereby a moment transmitted to the first unit is transmitted to the second unit. Each coupling member comprises a torque transmitting component having a central portion of a radial dimension defined by a radius of a circle inscribed therein and at least one arm extending from the central portion to periphery of the corresponding coupling member. The arms of the male and female coupling members have first side walls along which the coupling members generally contact and second side walls having a gap therebetween. The first walls are directed, at least at their contact regions, substantially radially with respect to the longitudinal axis.
