RUKO SPB-DIN338-HSSCo8-TiAlN-Ø6.4mm Twist Drill Bit

Drilling into high-alloy steels, stainless steel, cast iron, titanium alloys, or hardened materials quickly dulls standard bits and creates excessive heat. This RUKO twist drill bit is engineered to handle those demanding jobs without losing its edge.

Who is it for

Professional machinists and serious metalworkers who need reliable performance in tough materials. It suits workshop use on drill presses, lathes, and hand drills where precision and durability matter.

Main features

• HSS-Co 8% cobalt steel withstands high temperatures and maintains hardness.
• TiAlN coating reduces friction, improves wear resistance, and extends tool life.
• Split point (130°) self-centers and reduces walking, so you can start holes accurately without a center punch.
• Fully ground flutes ensure smooth chip evacuation and a clean finish.
• Right-hand cutting direction for standard drilling operations.
