RUKO HSS-TiN Twist Drill Bit DIN 338 10.4mm

Precision drilling in tough materials demands a bit that stays sharp and resists heat. The RUKO HSS-TiN Twist Drill Bit DIN 338 10.4mm meets that need with a titanium nitride coating over high-speed steel, delivering clean holes in steel, cast iron, non-ferrous metals, and plastics.

Who is it for

Metalworkers, machinists, and serious DIYers who need a reliable, long-lasting drill bit for production or repair work. The TiN coating reduces friction and heat, extending tool life and improving hole quality.
