RUKO SPB-TX-DIN338-HSSCo-Ø11,0mm HSS-Co koboltti kierrepora DIN 338, 11,0 mm

Drilling into tough materials like stainless steel or heat-resistant alloys demands a drill bit that stays sharp and withstands high temperatures. The RUKO SPB-TX-DIN338-HSSCo-Ø11,0mm is a cobalt-alloyed HSS twist drill bit engineered for exactly these challenges. Its 5% cobalt content provides enhanced heat resistance and hardness, allowing it to maintain cutting performance in demanding applications.

Who is it for

This drill bit is intended for professionals and serious DIYers who regularly work with stainless steel, acid-resistant steel, heat-resistant steel, cast iron, bronze, and plastics. It is suitable for materials with a tensile strength up to 1100 N/mm².

Tips

Use cutting fluid or coolant when drilling stainless steel to extend tool life. Ensure the drill is held securely in a chuck with appropriate tightening. For best results, pre-drill with a smaller diameter bit when drilling large holes in hard materials.
