Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides an interior crisscross sword PCD of cooling mills tooth sword, includes handle of a knife 1, cutter arbor 2 and tool bit 3, tool bit 3 passes through 2 fixed mounting in 1 one end of handle of a knife of cutter arbor, cold hole 4 in 1 inside having seted up of handle of a knife, 4 one ends in the cold hole extend to 1 tip of handle of a knife, the 4 other ends in the cold hole run through cutter arbor 2 and extend to 3 tip of tool bit, 3 outer wall surfaces of tool bit are provided with cutting teeth 5 and chip groove 6, and chip groove 6 is located 5 one side of cutting teeth. The position of the inner cold hole 4 is aligned with the knife tip part of the tool bit 3; during the use, because the position of interior cold hole 4 aims at the knife tip position of tool bit 3, when the cutter cut the work piece, tool bit 3 can produce a large amount of heats, and at this moment interior cold hole 4 can in time discharge the produced heat of tool bit 3 cutting, avoids the heat to pile up on tool bit 3 and influence the cutting effect of cutter, also can not cause the damage to the work piece simultaneously.

The cutting teeth 5 comprise a plurality of cutter edges 7 which are axially arranged at fixed intervals, and the cutter edges 7 are provided with a plurality of groups; wherein, the cutting teeth 5 are distributed on the periphery of the cutter head 3 in a staggered structure, and the cutting teeth 5 are arranged in trisection; when the tool is used, the tool is a staggered edge, the cutting force of the tool on a workpiece can be effectively reduced, and the cutting efficiency can be improved.
