Gold-black metal drill bits made of 4341 HSS high-speed steel, coated with TiN (titanium nitride). The drill bits comply with DIN 338 standard and feature a cylindrical shank. Designed for drilling through and blind holes, they have two central cutting edges ground at a 135° angle and flutes that effectively remove chips upwards. TiN-coated drill bits are particularly suitable for machining difficult-to-cut materials. The TiN coating increases the drill bit's hardness, enables faster cutting, and improves the quality of machined components. The titanium nitride layer reduces friction, decreasing blade wear and extending the drill bit's lifespan. The drill bits are packed in a plastic container with a hanging hole. Product characteristics: drill bit made of HSS 4341 high-speed steel, TiN (titanium nitride) coated, very good chip removal thanks to the ground spiral, 2-step tip ground at 135°, perfectly ground cutting edge. Technical specification: Steel: HSS 4341, Coating: TiN, Size: 8.00 mm, Tip: 2-step, ground at 135°, Shank: cylindrical.
