Drill bit Proline 71216, metal, Ø12 mm, length 160 mm, 1 pc

Proline 71216 metal drill bit, single piece with 12 mm diameter and 160 mm overall length. This straight-shank bit is designed for drilling metal and other hard materials where an extended reach is required. The 160 mm length provides the capacity for through-holes and deeper drilling in workshop, construction and repair applications, and the single-piece supply is suitable for use with hand drills and drill presses that accept standard straight shanks.

Advantages

The Proline 71216 drill bit combines a 12 mm cutting diameter with a long 160 mm working length to reach deeper drilling positions without changing tooling. Its straight shank ensures compatibility with most chucks while the metal-specific cutting geometry supports stable chip evacuation and consistent hole size. Supplied as one piece, the bit is ready for immediate installation and use in routine metalworking and repair tasks.

Suitable for

• Drilling through steel and other metals where a 12 mm hole is required
• Deep or through-hole drilling jobs in workshops and construction sites
• Use with hand drills and drill presses that accept straight shanks
• General repair and maintenance tasks requiring a long metal bit

Key specifications

• Material application: metal and similar hard materials
• Cutting diameter: 12 mm
• Total length: 160 mm
• Shank type: straight shank compatible with standard chucks
• Supply: 1 piece

How to use

Secure the Proline 71216 drill bit in a compatible chuck and set the drill or drill press to an appropriate speed for the metal being machined. Use cutting fluid or lubricant when drilling harder metals to reduce heat and improve chip removal. Apply steady pressure, retract periodically if drilling deep to clear chips, and finish the hole with controlled feed to maintain accuracy and bit life.

Usage recommendations

For best results, use cutting fluid on steel and stainless steel, select a moderate drill speed to avoid overheating, and ensure the workpiece is clamped securely. Inspect the bit for wear before use and replace if the cutting edges become dull to maintain hole quality and operator safety.
