Advantage
1.It can reduce drilling resistance and itis axial force reduces nearly 30% and torque reduce 15% compared with common twists.
2.This improvement decreased drilling heat and lower temperature of cutting edge.
3.It relieves abrasion of cutting edge,improves durability of drill and enbance productivity of 3-5 times.
4.It improves the situation of chip removal and breaking and safety of operation.
5.It is convenient to made cutting fluid flow into cutting area.
6.Drills can cut into workpieces quickly and have good centering ability.
