Long HSS M2 8.0mm Black & Gold Metal Twist Drill Bit

Description

Extended black and gold metal drill bit made of M2 HSS high-speed steel, coated with TiN (titanium nitride). The drill bit complies with DIN 340 standard. Cylindrical shank. The drill bit is designed for making through and non-through holes. It has two central cutting edges ground at a 135° angle and flutes that effectively remove chips upwards from the hole. The TiN-coated drill bit is particularly suitable for machining hard-to-cut materials. The application of the TiN coating increases the hardness of the drill bit, enables faster cutting, and allows for better quality of machined elements. The titanium nitride layer reduces friction, thereby decreasing wear on the cutting edge and extending the drill bit's lifespan. The drill bit is packaged in a blister with a hook hole. Product features: drill bit made of HSS M2 high-speed steel, extended drill bit compliant with DIN 340 standard, TiN (titanium nitride) coated, very good chip evacuation thanks to the ground spiral, 2-step tip ground at a 135° angle, perfectly ground cutting edge. Technical specifications: Steel: HSS M2, Coating: TiN, Size: 8.00 mm, Total length: 165 mm, Working length: 109 mm, Tip: 2-step, ground at 135°, Shank: cylindrical.
