HSS 6.80mm Black & Gold Metal Twist Drill Bit

Description

Black and gold metal drill bits made of 4341 HSS high-speed steel, coated with TiN (titanium nitride). Drill bits comply with DIN 338 standard. Cylindrical shank. The drill bits are designed for making through and non-through holes. They have two central cutting edges ground at a 135° angle and flutes that effectively remove chips upwards from the hole. TiN-coated drill bits are particularly suitable for machining difficult-to-cut materials. The TiN coating increases the hardness of the drill bit, allows for faster cutting, and helps achieve better quality of machined elements. The titanium nitride layer reduces friction, decreases wear on the cutting edge, and thus extends 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, coated with TiN (titanium nitride), very good chip removal thanks to the ground spiral, 2-step tip ground at 135°, perfectly ground cutting edge. Technical specifications: Steel: HSS 4341, Coating: TiN, Size: 6.80 mm, Tip: 2-step, ground at 135°, Shank: cylindrical.
