## Summary description

Cobalt metal drill bit by GRAPHITE, 10 mm diameter with a cylindrical (walcowy) shank, model 57H054. Designed for drilling ferrous and hard metals where higher heat resistance and wear durability are required. Suitable for use in handheld drills and drill presses for metalworking tasks such as hole making, fitting and maintenance.

## Long description

Cobalt Metal Drill Bit GRAPHITE 10 mm, cylindrical shank, model 57H054 is a precision tool designed for drilling into ferrous and other hard metals. Made with a cobalt alloy cutting tip and a cylindrical shank, this 10 mm drill bit is intended to deliver improved heat resistance and extended wear life compared with standard high-speed steel bits. It is suitable for use in both handheld drills and drill presses in metalworking environments where consistent hole quality and tool durability are required.
Advantages
The cobalt composition of the cutting edge ensures higher hardness at elevated temperatures, which reduces tool wear during extended drilling of steel and stainless materials. The 10 mm diameter delivers a balance between rigidity and material removal rate for common metalworking tasks. The cylindrical shank provides compatibility with standard drill chucks and allows secure clamping for both portable and stationary drilling equipment. The overall design focuses on stable chip evacuation and consistent hole geometry when used at appropriate speeds and with cooling.
Suitable for
Drilling holes in ferrous metals, including steel and stainless steel
Maintenance and repair tasks requiring precise metal hole making
Workshop and production operations using handheld drills or drill presses
Fitting and assembly work where durable, repeatable drilling is needed
Key specifications
Diameter: 10 mm
Material: cobalt-alloy cutting tip with high-speed steel body
Shank type: cylindrical (straight) shank compatible with standard chucks
Intended use: ferrous and hard metals, including stainless steel
Typical applications: drilling, fitting, maintenance in metalworking
How to use
Secure the drill bit in a properly tightened chuck and select a drilling speed appropriate for the material being worked—lower speeds for stainless and hard steels, higher speeds for softer steels. Apply cutting fluid or coolant to reduce heat buildup and extend tool life. Use steady, moderate feed pressure; avoid excessive force that can overheat or break the bit. When drilling deeper holes, periodically withdraw the bit to clear chips and reapply coolant as needed. After use, clean the bit and store it in a protective holder to prevent damage and corrosion.
Usage recommendations
For best results when drilling stainless steel and other hard alloys, use a conservative speed setting, continuous or frequent coolant application, and moderate feed pressure. Replace the bit if chipping or significant wear is observed to maintain hole quality and operator safety.
