In this way, for inner ring by bit bore, deformation reduces milling cutter when milling cutter rotation carries out crushing Peripheral Bone bits
Intensity needed for working；Constantly perseveration can completely take away bone bits up and down when such setting needs early to carry out brill bone
The bone hole bored.
Further, the bit central bar and the connection type of drill bit are be threadedly coupled, weld or block cast molding.
In this way, when the connection type is to be threadedly coupled, it is desirable that it is opposite with rotation direction that its screw thread screws direction.
Further, hollow duct is equipped with inside the bit central bar；Correspondence is set in bit central bar and drill bit junction
There is bleeding holes.
In this way, being easy to produce high temperature since main or bit operation intensity is larger, it is perfused and is cooled down by hollow duct
Liquid is realized and cools down to drill bit and center cooling rod.
Further, the drill bit is screw thread drill bit, double ditch gouge bits or three ditch gouge bits.
In this way, increasing versatility.
The beneficial effects of the present invention are: the present invention to pass through the milling cutter of setting auxiliary circle annular distribution compared with prior art
To reduce the working strength of drill bit；Realize slight cooling；The milling cutter milling that bone bits near drill bit rotation simultaneously can be assisted is broken
And tooth guidance discharge is turned by gap and screw thread, bone bits are quickly taken away, the possibility that bone split occurs when boring bone is greatly reduced；
And cooling is realized by way of coolant liquid is perfused in hollow bit central bar, and guarantee that temperature of diamond bit is not too high, it is cooling simultaneously
Liquid also can quickly be discharged from annular through-hole, form a circulation, constantly take away the heat generated when boring bone, and realizing reduces drill bit
Temperature protects the benefit of periphery bone.
