HSS 4.00mm Black & Gold Metal Twist Drill Bit

Description

Gold-black metal drill bits made of 4341 HSS high-speed steel, coated with TiN (titanium nitride). 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 hard-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, decreases wear on the cutting edge, and thus extends the life of the drill bit. The drill bits are packed in a plastic container with a hole for hanging on a hook. Product features: drill bit made of HSS 4341 high-speed steel, coated with TiN (titanium nitride), very good chip removal thanks to ground spiral, 2-step tip ground at 135°, perfectly ground cutting edge. Technical specification: Steel: HSS 4341, Coating: TiN, Size: 4.00 mm, Tip: 2-step, ground at 135°, Shank: cylindrical.
