Drill bit Proline 71021, 10 mm diameter, 210 mm length, metal

Single Proline 71021 metal drill bit with 10 mm diameter and 210 mm overall length. The bit is intended for drilling metal and features a straight shank compatible with hand drills and drill presses. Supplied as one piece, this 10 mm diameter, 210 mm length drill bit is suitable for tasks in metalwork, fabrication, maintenance and repair where a medium-length hole is required.

Advantages

The Proline 71021 drill bit delivers a consistent 10 mm hole with a 210 mm overall length that balances reach and rigidity. Its straight shank ensures secure clamping in standard chucks, and the single-piece construction reduces the risk of slippage during operation. Designed for metal drilling, the bit provides reliable cutting performance for general-purpose industrial and workshop applications.

Suitable for

• Drilling through steel sheets and metal plates
• Fabrication and assembly work in workshops
• Maintenance and repair tasks requiring medium-length holes
• Use with hand-held drills and drill presses

Key specifications

• Diameter: 10 mm
• Overall length: 210 mm
• Material suitability: metal
• Shank type: straight shank
• Packaging: single piece

How to use

Secure the drill bit in the chuck of a hand drill or drill press, ensuring the straight shank is clamped firmly. Select an appropriate cutting speed and use cutting fluid or lubricant where recommended for the metal being drilled to reduce heat and extend tool life. Apply steady, moderate pressure and allow the bit to cut rather than force it; withdraw periodically to clear chips when drilling deeper holes. After use, clean and store the bit in a dry location to prevent corrosion.

Usage recommendations

For best results when drilling metal, choose a suitable lubricant, match cutting speed to material hardness, and avoid excessive feed pressure. Use proper personal protective equipment and ensure workpieces are securely clamped.
