The beneficial effects of the utility model：The handle of a knife is equipped with transition shoulder, and the transition shoulder is equipped with positioning table
Rank can control drilling depth, play positioning action, prevent due to being damaged due to the inertia of drill thrust when plate drills
Cutting edge or clamp body；The positioning step is equipped with clearance position so that the scrap being discharged by circular arc chip space has space progress
Short time stops, and card caused by avoiding scrap from being stuck among cutting edge and machined material stops or tipping phenomenon；The clearance position
It is equipped with cutter hub, the drill bit is bored equipped with centralized positioning step, and drill bit is equipped in the cutter hub, and the drill bit is equipped with liftout
Spring provides better equilibrant force when the pressure of liftout spring being enable to drill, and harmony is more preferable, in addition in drilling at the end of side
Just core material pops up among drill bit.
