The invention discloses a diamond saw blade, and belongs to the technical field of diamond tools. A saw blade base body is made of 30CrMo steel, and a diamond tool bit is formed by evenly mixing raw material powder and then conducting cold press molding and hot press sintering. The diamond tool bit is prepared from the following raw materials in parts by weight: 18-28 parts of copper, 35-45 partsof iron, 3-18 parts of nickel, 2-10 parts of cobalt, 2-10 parts of tin, 3-12 parts of rare earth and 5-10 parts of WC powder, 0.4-1.2 parts of liquid paraffin and 0.8-2.1 parts of diamond are added; and the rare earth is Y or La powder. By means of the optimized design of the material composition of the tool bit and the structure of the saw blade, the tool bit is embedded into the saw blade base body in a cold pressed joint mode, and reliable connection of the tool bit and the base body is achieved.

The invention provides a metal cutting tool. The metal cutting tool comprises a tool bit and a tool handle, the tool bit is arranged at one end of the tool handle and comprises an outer cutter, an inner bore cutter, a first cutter groove and a second cutter groove, the first cutter groove is perpendicular to the second cutter groove, and the tool handle comprises a tool bit locking device and a tool bit fixing device. Due to replacement of an original one cutter with two cutters and arrangement of the first cutter groove and the second cutter groove, cutter amount can be increased with cutter position unchanged, and cutter change is not needed during cutting of inner bores, so that procedures are simplified, a great deal of time is saved, and operation efficiency is improved. Moreover, since the tool handle is provided with the locking device and the fixing device, stress uniformity in use can be achieved; owing to an extension rod arranged on the tool handle, the tool handle can be lengthened in special occasions, so that the metal cutting tool is more convenient to use and more humanized.

The invention discloses a processing and production device for spiced duck.
