Cause to get stuck.
4. plug coordinates with slot, being detachably connected for broken bone drill head can be realized, moreover it is possible to effectively transmit torque.
5. buckle can ensure to bore bone, the stability of broken bone drill head, plug is avoided to be come off from jack.
6. buckle does not influence machine handle and is connected with rig without departing from the periphery of machine handle.
7. the cross section of scrap leading tunnel is circular arc, bone bits can be avoided to be caught in dead angle.
8. the depth of length≤Hollow barrel of broken bone drill head, when can ensure to bore bone, bone table is first sawed by the sawtooth of annular
Face forms annular groove, then by the broken broken bone of bone drill head, can avoid that bone split occurs during drilling.
9. broken bone drill head, sawtooth are hard alloy material, bone can be bored to broken, cutting accuracy height easily, it is laborsaving, and
And long lifespan.
