- ADVANCED MATERIAL – Our countersunk drill bits are made of industrial grade M35 cobalt high speed steel. It has been well improved in terms of wear resistance and durability. It is better than the HSS material on the market.
- TiAlN COATING – Titanium aluminum nitride coating is a coating developed on the basis of aluminum nitride titanium. The content of aluminum (TiAlN) in the coating is further increased, so the oxidation resistance of the coating is further improved, the maximum heat-resistant temperature can reach 1000 ℃, and the hardness of the coating is also improved, up to 4200HV.
- SHAPE – The hollow design of the drill bit allows debris to escape more easily. It will not hinder the line of sight and the progress of drilling. The sharp angle of 82 degrees meets the needs of most countersunk heads. The handle body of the round handle can be applied to the drill rigs on the market.
- APPLICABILITY – Constructed of TiAlN coating and industrial-grade M35 cobalt high-speed steel material, our drill bits can not only easily cut wood, plastic, acrylic sheet, fiberglass and other soft metals, but also stainless steel, steel, sheet metal, aluminum alloy and cast iron, etc. hard metal
- WARRANTY – If you’re not 100% satisfied with the Countersink Bit simply return it for a full refund in 30 days, no questions asked money back guarantee with 12 months’ warranty
