RUKO LOS-HSSCo-98mm HSS-Co5 spiraalboor 6,0 mm DIN 338

This twist drill bit from RUKO GMBH is engineered for high-performance drilling in tough materials. The 5% cobalt alloyed high-speed steel (HSS-Co5) delivers superior heat resistance and durability, making it ideal for stainless steel, alloyed steels, and cast iron. With a 135° split point, it starts fast and cuts accurately without wandering.

Advantages

The HSS-Co5 construction provides excellent hardness and wear resistance, extending tool life even under high-stress conditions. The bright polished finish reduces friction and chip adhesion, while the type N helix angle ensures efficient chip evacuation in normal drilling applications. The cylindrical shank fits standard drill chucks, and the h8 tolerance guarantees precise hole diameters.

Suitable for

• Alloyed and unalloyed steels
• Stainless steel
• Cast iron
• Non-ferrous metals
• Plastics
