## Summary description

Cobalt metal drill bit GRAPHITE 57H052 with a 9.5 mm diameter and cylindrical shank, designed for drilling hardened steels and general metalworking. The high-cobalt composition increases heat resistance and wear life, suitable for use in hand drills and drill presses. Ideal for workshop, industrial and maintenance tasks requiring precise holes in metal.

## Long description

The GRAPHITE 57H052 cobalt drill bit is a 9.5 mm diameter metalworking drill with a cylindrical shank, engineered for drilling hardened steels and common metals. Its high-cobalt composition increases heat resistance and hardness, extending cutting life when used in hand drills and drill presses. The bit provides reliable performance for workshop, industrial and maintenance tasks requiring precise, repeatable holes in metal components.
Advantages
The cobalt alloy construction offers improved wear resistance and thermal stability compared with conventional HSS bits, enabling drilling at higher speeds and under greater thermal load. The 9.5 mm diameter and ground tip geometry support accurate hole positioning and reduced walking at the start of drilling. The cylindrical shank fits standard drill chucks, allowing secure clamping and versatility between portable drills and bench-mounted machines.
Suitable for
Drilling hardened steels and heat-treated metal parts
General metal fabrication and repair work
Workshop maintenance and mechanical servicing
Use in hand drills and drill presses for precision holes
Key specifications
Material: high-cobalt alloy (cobalt-enhanced high-speed steel)
Diameter: 9.5 mm
Shank type: cylindrical shank for standard chucks
Intended use: metal drilling, including hardened steels
Tip geometry: ground for reduced walking and improved centering
How to use
Select an appropriate drilling speed and apply steady feed pressure consistent with the workpiece material and drill diameter. Secure the workpiece to prevent movement and center-punch the drilling position to improve accuracy. Use cutting fluid or coolant when drilling hardened steels to reduce heat buildup and prolong tool life. After drilling, clear chips frequently and inspect the cutting edge for wear before continued use.
Usage recommendations
For best results when drilling hardened metals, use moderate to high spindle speeds with adequate coolant, avoid excessive side forces, and replace the bit if chipping or excessive wear is observed to maintain hole quality and operator safety.
