According to the above configuration, since the crack-proof composite notch blade 29 and the crack-resistant composite notch blade 28 are respectively provided on the notch edge 13 and the notch edge 14, the cutting force of the cutting edge 6 is decomposed, so that the cutting bit 9 is The crack resistance of the cutting edge is increased during the cutting process.

With such a configuration, in addition to the technical effects of the first to fifth embodiments, since the heat dissipating surface 10 is formed, the crack-resistant composite cutting edge 12 can be further decomposed to reduce the punching resistance and frictional force of the cutting insert 9, and the length is extended. Service life.

In the process of the first to eighth embodiments, a taper tip or a cutter head 3, a ring cone or a ring arch 4 is provided, and by adding a crack-resistant composite positioning hole 15, a plurality of positioning grooves 16 or positioning holes 15, The cost of the cutter head is greatly reduced, so that the combination of the cutter head and the pick body or the gear body is stronger and the efficiency is improved. The heat is dissipated by the notch 13 on the cutting edge 6 or the crack resistant composite cutting edge 12 The groove 14 forms a highly efficient heat sink for the cutting edge to maintain high strength at all times.

All of the above embodiments of the high-efficiency crack-resistant and low-dust cutter head can be configured on different cutters or drills to decompose the punching resistance and friction, and improve the heat dissipation efficiency.

Although the above is provided with a convex taper tip or a small round head, a stepped ring cone or a ring arch body, a ring cone or a ring arch body, and a groove provided on the shank, the ring cone or the ring body is provided with a cutting. The blade 6, the minor cutting edge 7, the front cutting face 1, the cutting edge 6, the front cutting face 1 1 are provided with a crack-resistant composite cutting edge 12 and a heat dissipating surface 10, a cutting edge 6 or a notch on the crack-resistant composite cutting edge 12. The blade 13, but the high-efficiency crack-resistant and low-dusting cutter head of the present invention may also have a multi-stage annular cone or ring arch, a multi-stage cutting edge, and a plurality of notch edges, and the above structure may be implemented as described above. The structure of the method and any other combination of forms.

The above-described preferred embodiments are illustrative and not restrictive, and the invention may be embodied and embodied in other forms without departing from the spirit and scope of the invention. The scope of the invention is defined by the claims, and all modifications within the scope of the claims are intended to fall within the scope of the invention.
