## Summary description

Cobalt drill bit for metal by GRAPHITE, cylindrical shank, diameter 5.5 mm (57H036). Designed for drilling hardened and non‑hardened steels and other metals where increased wear resistance is required. Features cobalt alloy cutting tip for higher heat tolerance and longer life, suitable for hand drills and drill presses when precise metal drilling is needed.

## Long description

GRAPHITE cobalt drill bit for metal, cylindrical shank, 5.5 mm is engineered for drilling into hardened and non‑hardened steels and a range of other metals. The drill features a cobalt alloy cutting tip that increases heat tolerance and wear resistance compared with standard HSS bits. The cylindrical shank ensures secure clamping in hand drills and drill presses, enabling accurate hole-making in metalworking tasks where edge life and dimensional stability matter.
Advantages
The cobalt cutting tip provides improved resistance to high temperatures and abrasive wear, extending tool life when drilling tough materials. The cylindrical shank offers reliable grip in standard chucks and reduces runout for better hole quality. Designed specifically for metal, this bit maintains cutting performance under heavier feed and moderate speed, making it suited for repeated use in workshop and industrial environments.
Suitable for
Drilling hardened and non‑hardened steel
Creating precise holes in various metals and alloys
Use with handheld electric drills and bench drill presses
Workshop repair, fabrication, and maintenance tasks
Key specifications
Material of cutting tip: cobalt alloy for increased heat tolerance
Shank type: cylindrical shank for standard chuck clamping
Drill diameter: 5.5 mm
Intended use: metal drilling, including hardened steels
Compatibility: suitable for handheld drills and drill presses
How to use
Secure the drill bit in the drill chuck so the cylindrical shank is fully clamped and runout is minimized. Select an appropriate cutting speed and feed for the material being drilled—lower speeds for harder steels and higher speeds for softer metals—while applying steady pressure. Use cutting fluid or lubricant when drilling steels to reduce heat buildup and prolong the life of the cobalt tip. Withdraw the bit periodically to clear chips and prevent clogging.
Usage recommendations
For best results, start with a pilot hole for large depth or diameter requirements, maintain correct spindle speed and feed rate for the metal type, and use appropriate cooling or cutting oil to maximize tool life and hole quality.
