Tungsten Solid Carbide Flat Bottom Drill Bits Cutter

Tungsten Solid Carbide Flat Bottom Drill Bits Cutter

1.HRC: HRC45 HRC55 HRC58 HRC60 HRC65

2.Coated: AlTiN, TiAlN, TiAISI,TiSiN, TiN, DLC,Nano, Diamond

3.Could be used for the processing of copper, cast iron, carbon steel, mould steel, stainless steel, titanium alloy, tool steel, and heat-treated steel

Products Features:

1. Special Designed Drill Tip: Special designed drill tip will increase the Centering Ability and Chip breaker ability. Thus,the processing efficiency will be increased.

2. 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.

3. Heat-resistant Coating: With highly heat-resistant HELICA/ALTIN coating, can be used for high-speed processing.

4. Smooth and Wide Flute:Smooth and wide flute will remove the cuttings more easily.

5. High Quality Raw Material: The raw material is used of high toughness, grain-sized carbon tungsten.

6. 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.
