RUKO QLS-HSS-TiN-10/15 10-Piece HSS Twist Drill Bit Set with TiN Coating, 1-10 mm, DIN 338

Drilling into metal, wood, or plastic often means dealing with dull bits that overheat and wear out quickly. This 10-piece twist drill bit set from RUKO solves that problem with a titanium nitride (TiN) coating that reduces friction and improves heat resistance, keeping the bits sharper for longer. The set includes diameters from 1 mm to 10 mm, covering most common drilling tasks around the workshop or home.

Who is it for

This set is for DIYers, metalworkers, and professionals who need a reliable range of drill bits for cordless drills, electric drills, or drill presses. The TiN coating makes these bits especially useful for drilling in metal, where heat and wear are common issues.
