And second step, triangle shank is equipped with the first step and second step, hole making drill loads after electric drill, and electric drill clamps three
Bone knob portion, can effectively play anti-skidding effect.
It is preferred that, the cylindrical of the pilot drill is provided with liftout spring, and in boring procedure, liftout spring is gradually compressed, and bores
After hole is terminated, core ejection will be expected by liftout spring, liftout spring conveniently and efficiently can not only eject the core material after brill, and make
Obtaining hole making drill can improve the balance of cutter in drilling process.
It is preferred that, the cutter hub is provided with 6-8 cutting edge, and the cutter hub is provided with 6-8 chip area, and the chip area
Quantity is identical with the quantity of cutting edge, and chip area guarantees the smooth discharge of drilling cuttings energy, reduces the generation of built-up edge, is prevented effectively from bits card
The card caused in the middle of cutting edge and machined material stops and tipping phenomenon.
It is preferred that, the apex point portion of the pilot drill is provided with the 3rd step so that have cutting function stage by stage in drilling,
Effectively decompose the drilling resistance of pilot drill, reduction drills through the impulsive force of workpiece moment, it is to avoid pilot drill may striking work generation
Tipping, so as to affect drill effect.
It is preferred that, the cutter hub is provided with the 4th step, can make hole making drill that the effect of workpiece is blocked when drilling completely, it is to avoid
Due to being directly impinging on chuck in the presence of powerful inertia force when drilling.
It is preferred that, the cutter hub is provided with two circular holes so that knife bar can place spanner, fast and easy when dismounting with cutter hub
Dismounting, it is also possible to as depoling hole, greatly improve the speed of cleaning hole inner cylinder material core.
It is preferred that, the cutting edge is made using hard alloy material, so as to improve wearability.
The beneficial effects of the utility model：The end of knife bar is provided with external screw thread, and the cutter hub center is provided with outer for coordinating
The internal thread hole of screw thread a so that knife bar can be attached with the cutter hub of different size, if to need to change when in use
Processing different size of hole need to only change cutter hub, can also reduce the cost of charp tool, improve cutter service efficiency；Set on cutter hub
There is pilot drill, the pilot drill is provided with platform, and the knife bar is provided with screwed hole, and the platform is by screw and screwed hole
Cooperation is fixed on knife bar, it is ensured that pilot drill will not loosen when in use and displacement；Cutter hub is provided with several cutting edges, described
Cutter hub is provided with several chip areas, so as to real arbitrary surface can be processed；The shank of knife bar be provided with first step and
Second step, a diameter of 10mm of first step, a diameter of 13mm of second step, such that it is able to adopt most conventional general 1-13mm
