Abstract: A head replaceable cutting tool having a structure that can limit a machining cost when a clearance portion is formed in a portion at which a head is attached and detached, and also limit deformation of a shank is provided. The head replaceable cutting tool includes: a projection portion or a hole portion for attachment and detachment disposed in a head; a shank to which the head is attachable; a hole portion, to which the projection portion is removably attachable along a central axis, or a projection portion disposed in an end portion of the shank; a fastening member that presses the projection portion toward an inner circumference surface of the hole portion; and a fastened portion disposed in the shank to fasten the fastening member.

Abstract: A tool assembly for heavy duty machining includes an insert, tool and clamp for securing the insert to a rigid insert seat of the tool. The insert is a solid cutting insert including a single cutting edge located at a corner region thereof. At a diagonally opposed corner region the insert is not subjected to clamping forces.

Abstract: A swiss insert includes a chip former arrangement. The chip former arrangement includes a ridge separated on each side from a cutting edge's sub-edge by a chip surface. In a side view, each sub-edge extends in a straight line.

Abstract: A cutting tool having a tool holder assembly for removably securing a plurality of cutting inserts. The tool holder assembly includes a tool holder body with an insert receiving pocket formed in a front end portion thereof, and a multi-insert tool clamp connected to the tool holder body. The clamp has a tool holder connecting portion and an insert clamping portion spaced apart therefrom, the insert clamping portion including a clamping protrusion and a plurality of clamping fingers. A clamping passage separates the plurality of clamping fingers from the clamping protrusion. At least one clamping slot separates the plurality of clamping fingers, and a slot plane longitudinally bisects each clamping slot. The clamping protrusion laterally extends along a clamping axis transverse to the at least one slot plane, and the at least one slot plane intersects the clamping protrusion.
