Drill bit for the precise drilling of metal and wood, thanks to its self-centring cut.
1.The drill effectively reduces rocking when drilling.
2.Good centering, avoiding slipping, conducive to waste cutting discharge, increase drilling efficiency.
3.Reduced drilling resistance, more conducive to chip removal and cutting fluid flow into the spiral groove, reduce the cutting edge temperature, reduce the cutting edge wear.
4.Improved product productivity, drilling speed increased by 30 percent.
5.Improved bit durability and extended life by 50%.
