The utility model has advantageous effect：The utility model is designed by using big apex angle and big corner, ensures beating
When to reinforcing bar in armored concrete, the generation skidded and cutter head bursts apart is avoided, ensures the stationarity of cutting process, to extend
The service life of cutter head；By being arranged cutting edge at top boring work position, rather than conventional cut point, top can be slowed down
The rate of wear of drilling, while cutting efficiency is more preferably more stable, avoids suddenly encountering hardness bigger under the circumference of the high-speed rotation
Object when be not easy chipping cracking, especially touch reinforcing bar when avoid skidding；By adding in the design cutting of two shoulder of cutter head
Qiang Ren, when rotary-cut goes out big material grains, can carry out separating twice to bulky grain makes to accelerate the exclusion of dust
It is designed with the cutting angle for being higher by cutting edge, slows down grinding edge, extended cutter head and cut service life；Pass through arc vertical slot, translot
Design, powerful convection current can be generated under the circumference of the high-speed rotation, to quickly drive dust exclusion, accelerate bore
Hole speed improves working efficiency.
