Further, the peripheral end portion setting point of a knife protection part of the end sword rake face, end sword major first flank, and point of a knife Protection partial width H5 is 2%~3% × D2, and tool arc forming part R1 is arranged.

Further, the end sword is arranged four in the cutter head end face, and branch's angle A 3 of four end swords, A4 are 80 ° ~90 °, 90 °~100 °.

Further, the Zhou Ren includes all sword rake faces, all sword flanks；

The axial plane included angle A 5 of all sword rake faces and the cutter head is 0 °~6 °, the tooth tip week of all sword flanks and the Zhou Ren It is 6 °~12 to the included angle A 6 of section；All sword flank width H1 are 15%~18% × D2.

Further, the spiral angle A1 of the Zhou Ren is 30 °~45 °.

As a kind of preferred embodiment of the utility model, it is based on above content, unlike, the cutter head includes First angle Gash and two, the 2nd angle the Gash angle Gash, the angle A 10 at the first angle Gash are 25 °, the angle A 11 at the 2nd angle Gash It is 50 °, the height H6 at the first angle blade Gash is 30%~35% × D2.

The utility model has the beneficial effects that:

The milling cutter of the utility model is arranged two angles Gash in end sword and all sword fusion connection parts, solves existing skill It is easy to produce tipping when art processing stainless steel category end mill, chip removal is unsmooth, and the bad disadvantage of rigidity can achieve 2 times of original cutter Above Production Life, and cutter production capacity is improved, production efficiency is greatly improved, has saved great amount of cost.
