RUKO KEB-Set7tlg-TX-HSS-TiN 7-Piece HSS Twist Drill Bit Set with Titanium Nitride Coating, DIN 338, 135° Split Point, Sizes 2-10 mm

This 7-piece twist drill bit set from RUKO's TX series is built for precision drilling in metal. Each bit is ground from solid high-speed steel (HSS) and coated with titanium nitride (TiN), giving it a hard, low-friction surface that resists wear and improves chip flow. The 135° split point starts on contact without wandering, so you can drill accurate holes in steel, cast iron, non-ferrous metals, and plastics.

Highlights

• Set of 7 HSS twist drill bits with TiN coating
• Diameters: 2.0, 3.0, 4.0, 5.0, 6.0, 8.0, 10.0 mm
• 135° split point for self-centering and reduced thrust
• DIN 338 standard, cylindrical shank
• Supplied in a robust plastic storage case

In daily use

The TiN coating lowers friction and heat build-up, extending bit life when drilling tough steels. The split point eliminates the need for center punching on many jobs, and the cylindrical shank fits standard drill chucks. Use with corded or cordless drills and drill presses. For best results, apply cutting fluid when drilling deep holes or hard materials.
