## Summary description

Cobalt metal drill bit set by GRAPHITE, model 57H056-5, includes five 10.5 mm diameter bits with cylindrical (walcowy) shanks. Designed for drilling hard metals, the cobalt composition increases heat resistance and wear life. Suitable for workshop and industrial use on steel and other ferrous materials with handheld or machine drills.

## Long description

GRAPHITE cobalt metal drill bit set 10.5 mm with cylindrical shanks, 5 pieces, is designed for drilling hard and heat-resistant metals. The set includes five identical 10.5 mm diameter bits made from high-cobalt steel alloy to improve wear resistance and cutting life when working with ferrous materials. Each bit has a cylindrical shank suitable for use in hand-held drills, drill presses and other machine chucks that accept straight shanks.
Advantages
The cobalt composition increases heat resistance and reduces edge wear during high-speed drilling in hardened steels and other tough materials. Cylindrical shanks provide stable grip in standard chucks, while the consistent 10.5 mm diameter across all five bits ensures repeatable hole sizes for production or workshop tasks. The pack of five spare bits supports uninterrupted work and quick replacement when a cutting edge becomes dull.
Suitable for
 Drilling holes in hardened and high-strength steels
 Workshop and industrial metalworking operations
 Use with hand-held electric drills and stationary drill presses
 Maintenance, repair and fabrication tasks on ferrous materials
Key specifications
 Drill diameter: 10.5 mm
 Quantity in set: 5 pieces
 Material: cobalt alloy high-speed steel
 Shank type: cylindrical (straight) shank
 Intended material: steel and other ferrous metals
How to use
Secure the appropriate drill bit in the drill chuck and tighten firmly to prevent slipping. Select a drilling speed and feed rate suitable for cobalt bits and the specific steel grade being worked on—lower speeds for hard or heat-treated steels help extend tool life. Use cutting fluid or coolant to reduce heat and clear chips, and apply steady pressure to maintain alignment. After drilling, withdraw the bit periodically to clear swarf and allow cooling.
Usage recommendations
For best results, use a suitable cutting lubricant, moderate drilling speeds for hardened steels, and proper clamping of the workpiece. Replace bits from the set when wear reduces cutting performance to avoid overheating and workpiece damage.
