RUKO LOS-HSSCo-60mm broca helicoidal HSS-Co5 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.
