    摘要： A nitrogen-containing sintered hard alloy in which the content of the binder phase is at the highest level in an area to a depth of between 3 .mu.m and 500 .mu.m from its surface and its content in this area is between 1.1 and 4 times the average content of the binder phase in the entire alloy. Below this area, the content of the binder phase decreases gradually so that its content becomes equal to the average content of the binder phase at a depth of 800 .mu.m or less. The content of the binder phase in the surface layer is 90% or less of its maximum value. The depth of 800 .mu.m is a value at which the thermal conductivity is kept sufficiently high and at the same time a tool can keep high resistance to plastic deformation during cutting.

    摘要： A throw-away tipped drill has an insert removably connected to a shank for cutting a workpiece. The insert (31) and the shank (32) have mutually engaging surfaces respectively, and a slit (34, 39) is formed either in the insert (31) or in the shank (32) for mounting the insert to the shank, whereby the insert (31) is fixed to the shank (32) by an elastic force which is caused by an elastic deformation upon mutual movement of opposite surfaces of this slit (34, 39) in engagement of the insert (31) and the shank (32). Therefore, the insert (31) and the shank (32) are coupled by simple press fitting without any requirement for a screw or other connection, whereby the assembly is improved. The cutting edge of the insert (31) has an excellent wear resistance, adhesion resistance and thermal cracking resistance and the shank (32) has an excellent toughness while the drill is relatively low in costs, by employing surface-coated cemented carbide as the material for the insert while employing steel as the material for the shank.

    摘要： A hard sintered component of a cemented carbide or a stellite alloy having a complex three-dimensional shape and a small hole or the like and the high strength originally provided by the used material for making the component without any secondary working, is formed by injection molding a compact molding die having an inner mold surface roughness R.sub.max of not more than 3 .mu.m. Where a core pin is used the outer surface of the pin has a surface roughness R.sub.max of not more than 3 .mu.m. The compact is then sintered. The hard sintered component is composed of a cemented carbide or a stellite alloy. In such a hard sintered component, the surface of a complex three-dimensional shape such as a disc portion or a thin portion, or the inner surface of a small hole, is defined by a sintered surface which has a surface roughness R.sub.max of not more than 4 .mu.m.

Protrusions are provided in a chip breaker groove to extend from a central land toward the respective corners of the insert. Each protrusion has a breaker wall which is concave and curved such that chips produced always collide against the breaker wall at an angle of 10.degree.-40.degree. so that the chips are curled helically with a helix angle of 10.degree.-40.degree. and broken into small pieces reliably.
