A grooving blade for chip removing machining includes a cutting insert pocket and a damping arrangement fixed to the blade. The damping arrangement projects laterally with respect to at least one major surface of the blade. A grooving tool and a method of grooving a metallic workpiece are also disclosed.

An insert adaptor for parting off including an adaptor index axis and parallel adaptor first and second sides connected by an adaptor peripheral surface which extends peripherally around the adaptor. The adaptor peripheral surface is formed with at least three pockets and bearing surfaces extending between the pockets. Each of the pockets comprises resilient upper and lower clamp surfaces.

A turning tool includes a tool body extending along a tool axis and having a base on a tip of the tool body, a cutting insert detachably attached to the base, and a measurement device attached to the tool body. The measurement device has a first distance sensor which measures a distance to an object located radially outward of the tool axis.

A cutting insert includes a cylindrical body portion, a cutting portion, a first fitting portion, a second fitting portion, and a third fitting portion. The cutting portion includes a rake face and a flank face. A ridgeline between the rake face and the flank face constitutes a cutting edge. When viewed in the axial direction, the cutting portion is provided opposite to the third fitting portion relative to the insertion hole. When viewed in the axial direction, a straight line extending through an outer circumferential end of the cutting edge and a center of the insertion hole overlaps with the third fitting portion and is located between the first fitting portion and the second fitting portion. A third central angle is smaller than a first central angle and is smaller than a second central angle.

A high-speed machining tool made of a steel-bonded carbide and a method for preparing the same relate to the technical field of lathe tools made of steel-bonded carbides, and overcome the problems of traditional steel-bonded carbide lathe tools about low hardness and low toughness. The high-speed machining tool includes a skeleton, a main body, and a coating. The main body is consolidated by the skeleton from inside. The skeleton and the main body are both ringlike in shape. The main body has its outer surface covered by the coating. The high-speed machining tool is such made that the skeleton is hard and the main body is tough. The blade of the tool is hard and can transfer vibrations to the main body, thereby protecting the tool from brittle fractures and improving the overall performance of the tool.

A turning tool adaptor includes opposite first and second side surfaces and a peripheral surface which extends therebetween. The turning tool adaptor further includes a cutting portion with an insert retaining portion and a clamping portion which extends from the cutting portion. The clamping portion includes a protrusion which extends transversely from the first side surface. The protrusion includes a main abutment surface and spaced apart first and second adaptor clamping bores which open out to the second side surface and also to the main abutment surface. The turning tool adaptor has first, second and third abutment surfaces which are located between the top and bottom surfaces in a side view perpendicular to one of the side surfaces.

Cutting tool holders are disclosed that include vibration dampening elements. The vibration dampening elements may extend parallel to a longitudinal plane of the cutting tool holder. The vibration dampening elements allow the cutting tool holders to have a smaller width while still providing higher grooving depth.
