Preferably, the edges of the two ends of the cutter fixing handle are provided with first chamfer angles.

Preferably, the chip grooves are uniformly distributed on the side faces of the milling cutter section and the milling tooth section, and the number of the milling cutter sections is four.

Preferably, the milling thread is uniformly distributed on the milling thread section.

Preferably, the edges of the two ends of the cutter fixing handle are provided with a first chamfer angle and a second chamfer angle.

Preferably, the thread form angle of the thread milling section is 60 degrees.

Preferably, the helix angle of the flute is one of 30 °, 35 °, 42 ° and 45 °.

Preferably, the milling tooth section extends through the milling cutter section.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model discloses in, be provided with in the milling cutter section and mill the tooth section, and be provided with in milling the tooth section and mill the tooth screw thread, mill the screw thread through milling the tooth screw thread when rotatory on the work piece, the cutter can not need to beat the bottom outlet, directly mills screw thread then chamfer on the work piece, reduces the cutter and changes the number of times, improves machining efficiency.
