## Summary description

Cobalt drill bit GRAPHITE 57H064 for metal working, 12.5 mm diameter with a cylindrical (round) shank. Made from high-speed steel with cobalt alloy for increased heat resistance and wear life, suitable for drilling steel, stainless steel and other hard metals. Use in hand drills and drill presses for workshop and industrial metal fabrication.

## Long description

The GRAPHITE 57H064 cobalt drill bit is a 12.5 mm diameter cutting tool intended for drilling metal. Manufactured from high-speed steel with an added cobalt alloy, this 12.5 mm bit provides improved heat resistance and extended wear life when working with steel, stainless steel and other hard metals. The tool has a cylindrical (round) shank designed for use in hand drills and drill presses commonly found in workshops and industrial metal fabrication environments.
Advantages
The cobalt alloy construction increases hardness at elevated temperatures, reducing wear during prolonged drilling operations in hard materials. The high-speed steel core maintains toughness to resist chipping, while the precision-ground flute geometry supports effective chip evacuation and consistent hole quality. The cylindrical shank allows straightforward mounting in standard drill chucks and supports quick tool changes for both portable and stationary drilling equipment.
Suitable for
 Drilling through mild steel, alloy steels and stainless steel
 Metal fabrication tasks in workshops and small industrial settings
 Use with hand-held electric drills and drill presses
 Pilot holes and through-holes in sheet and plate metal up to appropriate thickness
Key specifications
 Diameter: 12.5 mm
 Material: high-speed steel with cobalt alloy
 Shank type: cylindrical (round) shank
 Intended use: cutting/drilling in steel, stainless steel and other hard metals
 Suitable equipment: hand drills and drill presses
How to use
Select appropriate rotational speed and feed for the 12.5 mm cobalt bit depending on the metal being drilled; lower speeds and steady pressure are generally recommended for stainless and hardened steels. Secure the workpiece in a vise or clamp, mark the drilling point, and, if necessary, start with a smaller pilot hole to improve accuracy and reduce tip loading. Use coolant or cutting fluid when drilling thicker sections or when sustained drilling causes temperature rise to maintain tool life and hole quality. After drilling, clear chips from the flute and inspect the hole for burrs, deburring as required.
Usage recommendations
To maximize life and performance of this cobalt drill bit, use appropriate cutting fluid, avoid excessive feed rates that can overload the tip, and match drill speed to material hardness. Store the bit in a protective case or rack to prevent damage to the cutting edges.
