HSS 3.00mm Black & Gold Metal Twist Drill Bit

Description

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 have a cylindrical shank. They are designed for making through and non-through holes. They feature 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 hard-to-cut materials. The TiN coating increases the hardness of the drill bit, enables faster machining, and allows for better quality of machined parts. The titanium nitride layer reduces friction, thus decreasing blade wear and extending drill bit life. The drill bits are packed in a plastic container with a hole for hanging on a hook. 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-stage tip ground at a 135° angle; perfectly ground cutting edge. Technical specification: Steel: HSS 4341; Coating: TiN; Size: 3.00 mm; Tip: 2-stage, ground at 135° angle; Shank: cylindrical.
