Product Description 8D Inner Coolant Drill 2 Flutes Solid Carbide Twist Drill Bits for Hardened SteelProducts Function: Raw MaterialCarbide, Tungsten Cobalt Alloy, tungsten carbideCoatingAlTiN, TiAlN, TiSiN, AlTiSiN, TiN, Nano, or as your requirementsOverall Length38-330mm (customized is acceptable)Flute Diameter0.3-40mm (customized is acceptable)Diameter4-40mm (customized is acceptable)Precision0.005-0.01 (high precision)HRC45/50/55/65 HRCControlling Modecnc tooling systemProcessing TypeFinishing MachingSuitable forwood, cast iron, carbon steel, mould steel, stainless steel, titanium alloy, tool steel, and heat-treated steel, etcProducts 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, the friction coefficient could be reduced, the lathe efficiency could be improved, more production time could be saved.Products Detail:1.
