Professional HSS-TiN metal drill bit set covering diameters 1–10 mm (in 0.5 mm steps) for precise drilling in steel, cast iron, and non‑ferrous metals. Fully ground bits with a 135° tip angle and split point ensure quick start, reduced feed pressure, and clean holes. The TiN coating reduces friction, limits chip adhesion, and significantly extends tool life.
This universal 19-piece set covers the most commonly used diameters from 1 to 10 mm and is ideal for workshops, maintenance, and DIY users. The HSS high-speed steel drill bits to DIN 338 are fully ground and feature a titanium nitride (TiN) coating for increased wear resistance and smoother chip evacuation.
Thanks to the 135° tip angle and split-point geometry, the bit bites quickly, wanders less, and requires lower feed pressure. They are suitable for alloyed and carbon steels, malleable and sintered cast irons, copper, and bronze. For maximum performance and service life, we recommend using cutting fluid.
