Drill bit Proline 71616 — 16 mm diameter, 160 mm length, metal drill

Proline 71616 is a single-piece metal drill bit with a 16 mm cutting diameter and 160 mm overall length. Intended for drilling holes in metal workpieces, it is compatible with hand drills and drill presses used in fabrication, installation and repair. The solid construction and double-twist design help maintain consistent hole size and improve chip evacuation during continuous use.

Advantages

The Proline 71616 drill bit combines a 16 mm cutting diameter with a 160 mm length to reach deeper drilling positions while preserving rigidity. Its double-twist flute geometry promotes faster chip removal and reduces clogging when working with metal. Manufactured as a single-piece tool, it offers stable concentricity for accurate, repeatable holes suited to mechanical and construction applications.

Suitable for

• Drilling holes in metal sheets, plates and structural parts
• Use with hand-held electric drills and bench drill presses
• Fabrication, installation and repair tasks in workshops and on-site

Key specifications

• Cutting diameter: 16 mm
• Overall length: 160 mm
• Material application: metal
• Single-piece construction for concentricity
• Double-twist flute design for improved chip evacuation

How to use

Secure the workpiece and mark the drilling position. Install the Proline 71616 drill bit into the chuck of a hand drill or drill press and tighten securely. Use an appropriate cutting speed and apply steady pressure; for metal drilling, use cutting fluid or lubricant to reduce heat and prolong tool life. Withdraw the bit periodically to clear chips if drilling deep holes. After finishing, clean chips from the flute and inspect the hole for required dimensional accuracy.

Usage recommendations

For best results when drilling metal, select suitable drill speeds and use cutting fluid. Match the drill capacity of your machine to the 16 mm diameter and ensure the chuck and bearings are in good condition to maintain accuracy.
