RUKO SPB-DIN338-HSS-TiAlN-Ø15,0mm broca helicoidal

Drilling precise 15 mm holes in tough metals like steel and stainless steel demands a bit that stays sharp and resists heat. The RUKO SPB-DIN338-HSS-TiAlN-Ø15.0mm twist drill bit solves this with a titanium aluminum nitride (TiAlN) coating that reduces friction and extends tool life, even under high cutting temperatures.

Who is it for

This drill bit is built for metalworkers, machinists, and maintenance professionals who need reliable performance in steel, stainless steel, cast iron, non-ferrous metals, and plastics. It suits both workshop and on-site applications where precision and durability are critical.
