Long HSS M2 5.5mm Black & Gold Metal Twist Drill Bit

Description

Extended gold-black metal drill bit made of HSS M2 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 difficult-to-cut materials. The TiN coating increases the hardness of the drill bit, enables faster cutting, and allows for better quality of machined parts. The titanium nitride layer reduces friction, thereby decreasing wear on the cutting edge and extending the drill bit's lifespan. The drill bit is packed in a blister with a hanging hole. Product features: - drill bit made of HSS M2 high-speed steel - extended drill bit compliant with DIN 340 standard - coated with TiN (titanium nitride) - very good chip removal thanks to ground spiral - 2-stage tip ground at 135° - perfectly ground cutting edge. Technical specification: Steel: HSS M2, Coating: TiN, Size: 5.50 mm, Overall length: 139 mm, Working length: 91 mm, Tip: 2-stage, ground at 135°, Shank: cylindrical.
