Cleveland C14822 Screw Machine Drill Bit 3.1 Mm Cobalt

Product Description

The CLEVELAND C14822 is a cobalt screw machine length drill bit designed for high-speed drilling in tough materials. At 3.1 mm (0.1220 inches) in diameter, it features a 135-degree split point that reduces walking on entry and lowers thrust force compared to a standard 118-degree point. The web-thinned, parallel web construction keeps the cutting edge aggressive through hard alloy and aluminum stock. With an overall length of 49 mm (1.929 inches) and a flute length of 18 mm, this short-body bit provides added rigidity in drill press, CNC, and screw machine applications. It is installed and used by machinists, maintenance technicians, and tool-and-die professionals working in metalworking environments.

This bit is suited for production drilling in alloy steels and aluminum where dimensional accuracy and hole finish are priorities. The screw machine length body reduces deflection in tight setups or short-travel drilling fixtures. The straight-cylindrical shank seats directly in standard drill chucks and collets without modification. It conforms to ASME B94.11M and DIN 1897 specifications, making it a direct fit for shops that work to ANSI or DIN tooling standards. Right-hand cut geometry is compatible with conventional spindle rotation on all standard drilling equipment.

Key Features

• Cobalt construction rated M42 grade for heat and wear resistance in hard metals
• 135-degree split point reduces drill walking and lowers entry thrust force
• Web-thinned parallel web maintains cutting efficiency and reduces heat buildup
• Screw machine length body provides rigidity over standard jobber-length bits
• Diameter tolerance held to +0.0000 to -0.0005 inches for consistent hole sizing
• Meets ASME B94.11M and DIN 1897 standards

Compatibility

Designed for use in standard drill chucks and collets accepting a 0.1220-inch straight-cylindrical shank. Suitable for drilling alloy steels and aluminum in drill press, CNC, and screw machine setups that require a short, rigid bit body per ANSI and DIN tooling specifications.

Installation Notes

Install in a properly sized drill chuck or collet and confirm shank seating before operation. Secure the workpiece firmly to prevent movement during entry. Use cutting fluid appropriate for the workpiece material to extend tool life and maintain hole tolerance. Inspect the cutting edges for wear before each use, as cobalt bits used on hard alloys will show tip wear that degrades hole accuracy.
