Drill bit Proline 71226, metal, Ø12 mm, length 260 mm, 1 pc

Proline 71226 is a single metal drill bit with a 12 mm diameter and a total length of 260 mm intended for drilling metal. The bit is suitable for use in standard drill chucks and is designed to create through and blind holes in steel and other ferrous materials. It is positioned for workshop repair, metal fabrication, maintenance and construction tasks where a long-reach, single-piece metal drill is required.

Advantages

The Proline 71226 drill bit delivers a consistent 12 mm bore with a 260 mm overall length that allows deeper reach than standard-length bits. Its geometry is designed to cut and evacuate metal chips efficiently, reducing sticking and improving hole quality in ferrous materials. Supplied as a single piece, it is compatible with common corded and cordless drills fitted with standard chucks.

Suitable for

• Drilling through and blind holes in steel and other ferrous metals
• Workshop repair and maintenance tasks requiring long-reach holes
• Metal fabrication where a 12 mm diameter hole is needed
• Construction tasks involving drilling into metal components

Key specifications

• Material application: metal / ferrous materials
• Diameter: 12 mm
• Overall length: 260 mm
• Pack quantity: 1 piece
• Compatibility: fits standard drill chucks

How to use

Clamp the workpiece securely and select an appropriate cutting speed for the metal being drilled. Fit the Proline 71226 bit into a standard drill chuck and tighten firmly. Use light, steady pressure and periodic backing out to clear chips; apply cutting fluid where appropriate to reduce heat and extend tool life. For blind holes, monitor depth carefully to avoid bottoming out; for through holes, continue until the desired breakthrough is achieved.

Usage recommendations

Use appropriate personal protective equipment, secure the workpiece, and select correct drill speed and lubrication for the metal type. Inspect the drill bit for wear before use and replace if damaged to maintain hole quality and safety.
