Drill bit Proline 71634 — metal, Ø16 mm, length 340 mm, 1 pc

Proline 71634 is a single metal drill bit with a 16 mm diameter and a total length of 340 mm, intended for drilling metal. It is designed for long-reach drilling tasks where a standard-length bit is insufficient. The drill bit is suitable for use with hand-held drills and drill presses and is intended for creating through-holes and clearance holes in steel and other ferrous materials in construction and workshop environments.

Advantages

The Proline 71634 drill bit offers a long overall length of 340 mm that enables access to deep or recessed drilling positions. With a 16 mm diameter it provides a balance between hole size and material removal rate appropriate for many metalworking tasks. The design supports reliable performance in ferrous materials and is compatible with common drilling equipment used in professional and industrial settings.

Suitable for

• Drilling through-holes in steel and other ferrous metals
• Clearance drilling for bolts and fasteners
• Long-reach drilling in assembly or repair work
• Use with hand-held drills and drill presses

Key specifications

• Diameter: 16 mm
• Total length: 340 mm
• Material application: metal / ferrous materials
• Quantity in pack: 1 piece
• Suitable equipment: hand-held drills, drill presses

How to use

Secure the workpiece and clamp it where possible to prevent movement. Mount the drill bit in the chuck and ensure it is properly centered and tightened. Select an appropriate cutting speed and apply steady feed pressure; use cutting fluid or lubricant when drilling steel to extend tool life and improve chip evacuation. Drill through the material with consistent speed, retracting occasionally if necessary to clear chips and reduce heat buildup. After use, clean chips from the flutes and store the bit in a dry place.

Usage recommendations

For best results when drilling steel and other ferrous materials, use moderate RPMs appropriate for a 16 mm diameter bit, apply cutting fluid, and avoid excessive feed force. When drilling deep holes, periodically withdraw the bit to clear chips and allow cooling. Verify compatibility of the bit with your drill's maximum chuck capacity and recommended speeds.
