HSS 3.30mm Black & Gold Metal Twist Drill Bit

Description

Black and gold metal drill bits made of HSS 4341 high-speed steel, coated with TiN (titanium nitride). The drill bits comply with DIN 338 standard. Cylindrical shank. The drill bits 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. 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 parts. The titanium nitride layer reduces friction, thereby decreasing blade wear and extending the drill bit's lifespan. 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 due to ground spiral, 2-stage tip ground at a 135° angle, perfectly ground cutting edge. Technical specification: Steel: HSS 4341, Coating: TiN, Size: 3.30 mm, Tip: 2-stage, ground at 135°, Shank: cylindrical.
