RUKO LOS-HSSCo-60mm HSS-Co5 spiraalboor 6,0 mm DIN 338

Drilling into tough materials like stainless steel or cast iron often causes bits to overheat, dull quickly, or wander off the mark. The RUKO LOS-HSSCo-60mm twist drill bit tackles these problems with a cobalt-alloyed high-speed steel body and a self-centering split point.

Who is it for

Metalworkers, maintenance technicians, and serious DIYers who need reliable holes in steel, stainless steel, cast iron, and non-ferrous metals using hand drills, drill presses, or stationary machines.

Main features

• HSS-Co5 cobalt steel withstands high drilling temperatures and resists wear.
• 135° split point starts on contact without a center punch and reduces walking.
• Fully ground flutes improve chip evacuation for faster, cleaner cuts.
• DIN 338 dimensions with cylindrical shank fit standard drill chucks.
• Bright/steam tempered finish for durability.

Tips

Use cutting fluid when drilling stainless steel to extend bit life. For deep holes, withdraw the bit periodically to clear chips.
