The application provides a special drilling tool for drilling a taper hole and a manufacturing method thereof, and steps are as follows: step 1, preparing a blank; step 2, processing a taper; step 3, processing a grinding groove; step 4, processing a main flank surface 2 of a chisel; step 5, grinding two main flank surfaces 1 of a drill tip; and step 6, grinding a first chip flute. The application is used for drilling a small inner hole and a large outer hole, effectively improves the drilling efficiency of the taper hole, and solves the processing problem of one-time forming of the taper hole.

The utility model relates to the technical field of diamond saw blades, in particular to a multi-notch diamond saw blade. According to the saw blade, the open grooves formed between the adjacent diamond tool bits extend towards the center of the saw blade base body, chippings generated in the cutting process can be effectively contained, chipping discharging is smoother, cutting resistance caused by chipping accumulation is reduced, and therefore the cutting efficiency is improved. The lengths of the adjacent open grooves are different, stress generated in the cutting process is effectively dispersed, the stress is prevented from being concentrated in a specific area, and therefore the influence on the strength of the saw blade base body is reduced, the structural stability of the saw blade base body is enhanced, and the service life of the saw blade is prolonged.

The utility model belongs to the technical field of machining tools, particularly relates to a wear-resistant and heat-dissipation integrated composite coating inner-cooling drill, and aims to solve the problems that a drill body of an existing device rotates at a high speed to cut into a workpiece, the temperature of a contact area is sharply increased due to strong friction between a drill tip and the surface of the workpiece, and the drill tip is thermally deformed due to overhigh temperature; in order to solve the problems that in the prior art, drilling precision is affected, and tool abrasion is accelerated, the following scheme is provided: the wear-resistant and heat-dissipation integrated composite coating inner-cooling drill comprises a drill handle, a drill body and a guide part; the drill bit has the advantages that the spiral chip grooves form a concave-convex structure on the conical surface of the guide portion, actual contact area of the drill bit and a workpiece is greatly reduced, friction force and heat generated by friction are reduced, temperature of the drill bit can be reduced, thermal deformation is reduced, service life of the drill bit is prolonged, dimensional deviation of the workpiece caused by thermal expansion can be reduced, and service life of the drill bit is prolonged. And therefore, the machining precision of the workpiece is further improved, and the high-quality machining effect is achieved.
