## Summary description

Cobalt metal drill bit by GRAPHITE, model 57H056, 10.5 mm diameter. High-speed steel with cobalt alloy for increased heat and wear resistance, straight shank, cylindrical (twist) geometry for through-holes in steel, stainless steel and hard alloys. Suitable for workshop and industrial drilling with handheld or stationary drills.

## Long description

GRAPHITE 57H056 cobalt metal twist drill bit, 10.5 mm diameter, is designed for drilling through steel, stainless steel and other hard alloys. Manufactured from high-speed steel with a cobalt alloy, the bit offers improved heat and wear resistance compared with standard HSS drills. The straight shank and cylindrical twist geometry ensure stable performance in both handheld and stationary drills, making it suitable for workshop and industrial applications where durability and precise hole quality are required.
Advantages
The cobalt alloy in the cutting material increases hardness at elevated temperatures, reducing wear during prolonged drilling of tough metals. The twist geometry provides efficient chip evacuation and maintains consistent cutting contact for clean, round holes. A straight shank enables secure clamping in standard drill chucks and collets, while the robust construction supports repeated use in demanding tasks.
Suitable for
 Drilling through mild and hardened steel
 Working with stainless steel and heat-resistant alloys
 Workshop and industrial production environments
 Use with handheld drills and bench or pillar drills
Key specifications
 Drill type: cylindrical (twist) metal drill
 Diameter: 10.5 mm
 Material: high-speed steel with cobalt alloy
 Shank type: straight shank for standard chucks
 Intended application: through-holes in steel, stainless steel and hard alloys
How to use
Secure the drill bit in the drill chuck or collet ensuring it is straight and tightened. Mark the drilling point and, if necessary, create a pilot dimple to prevent walking. Use appropriate cutting speeds and feed rates for cobalt HSS drills when working with stainless steel or hardened materials to avoid overheating. Apply cutting fluid or coolant for improved heat dissipation and longer tool life. Clear chips periodically and maintain steady pressure without forcing the bit.
Usage recommendations
For best results, select drill speeds lower than those used for carbon steel when drilling stainless or heat-resistant alloys, and use a suitable cutting fluid. When drilling thick or hard materials, consider peck drilling to remove chips and reduce heat buildup.
