Product Description
2 Flute Solid Carbide Step Twist Drill Bit with Long Cutting Edge
Products Function
1.HRC: HRC45 HRC55 HRC58 HRC60 HRC65
2.Coated: AlTiN, TiAlN, TiAISI,TiSiN, TiN, DLC,Nano, Diamond
3.Apply to:Could be used for the processing of plastic,wood, Aluminium.copper, cast iron, carbon steel, mould steel, stainless steel,
taitanium alloy, tool steel, and heat-treated steel
Products Feature
- Special designed drill tip: Special designed drill tip will increase the Centering Ability and Chip breaker ability. Thus,the processing efficiency will be increased.
- Much sharper cutting edge: The much sharper cutting edge can decrease the cutting resistance and and torque. The lifetime of tools and machines will be longer.
- Heat-resistant coating: With highly heat-resistant HELICA/ALTIN coating, can be used for high-speed processing
- Smooth and wide flute:Smooth and wide flute will remove the cuttings more easily.
- High quality Raw Material: The raw material is used of high toughness, grain-sized carbon tungsten.
- Polished surface treatment: With high polished surface treatment, reduce the friction coefficient could be reduced, the lathe efficiency could be improved, more production time could be saved
