摘要： The invention relates to a cutting tool made of ceramics, cermet or cemented carbide and including a rake face, a flank face and a cutting edge at the intersection of rake face and flank face, as well as a multi-layered wear resisting coating including a layer which is made of aluminum oxide and deposited on a hard material layer, in which for avoiding an increase in the width of wear mark, with simultaneous retention of the resistance to cratering of the rake face, the aluminum oxide layer of the coating is removed on the flank face and the underlying hard material layer is exposed at least in portions. The aluminum oxide layer of the coating is removed on the flank face preferably by means of laser beam treatment.

摘要： A sintered body insert for cutting comprises an intermediate layer consisting of at least one of cemented carbide, a ferrous metal and a high melting point metal, and a first layer and a second layer, each consisting of hard sintered bodies containing cubic boron nitride or diamond, which are arranged on opposite sides respectively above and below with the intermediate layer therebetween. The first and second layers are bonded to the intermediate layer by sintering. The is so formed or configured that its front and rear surfaces define cutting faces. All noses and flanks involved in cutting are formed on the first layer and the second layer, while the centers of gravity of the cutting faces and of the overall insert are located at positions on or in the intermediate layer. Further, coating layers consisting of a nitride of an element belonging to the group 4a, 5a or 6a of the periodic table or other components are formed on the surfaces of the cutting faces and the flanks. With this structure, it is possible to provide a sintered body insert for cutting which is prolonged in life and excellent in economy such as the manufacturing cost.

摘要： A hard metal cutting blade comprises a blade body having front and rear faces. The blade body is meant for engagement to a tool head and for rotation about a rotation axis. The blade is moved in a feed direction for the fine machining of bores that extend parallel to the rotation axis. The front face of the blade includes a recessed chip face which defines a cutting edge that has a main blade that is followed by a secondary blade. The main blade is divided into two regions, a first region that is almost flush or slightly inclined with respect to the secondary blade, and a second region which inclines at a greater angle and is spaced further from the secondary blade. An abrasion-resistant hard material coats the blade body. This material is ground away from the chip face, at least in the area of the secondary blade, to provide a radius of no more than 5 .mu.m for the edge of the secondary blade.
