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. 1-3, the present invention provides an embodiment: the cutter comprises a cutter body 1, a cutter neck 2 and a cutter handle 3, wherein the cutter neck 2 is arranged between the cutter body 1 and the cutter handle 3, the cutter body 1, the cutter neck 2 and the cutter handle 3 are arranged on the same axis, the cutter body 1 comprises a cutter core 11 and a plurality of U-shaped grooves 12, the plurality of U-shaped grooves 12 are arranged around the cutter core 11 and used for containing and discharging generated scraps, and the core diameter of the cutter core 11 is 55% of the outer diameter of the cutter body 1; with the core footpath with the core 11 by original cutter body 1 external diameter 65% change 55%, make the setting at core 11U type groove 12 all around bigger, increased its hold bits and chip removal ability, in tungsten steel milling cutter course of working, U type groove 11 can hold more sweeps that produce, can enough improve tungsten steel milling cutter's work efficiency when the production is processed, guarantee that the product that simultaneously also can bigger degree is more level and more smooth with tungsten steel milling cutter's contact surface.
