Drill bit Proline 16 mm, model 76416, single metal drill bit

The Proline single metal drill bit with a 16 mm diameter is designed for straightforward hole-making in metal materials. Manufactured for use with handheld drills and drill presses, this solid cutting tool is intended to produce precise 16 mm holes in sheet metal, structural steel and similar metalwork. The item is supplied as a single bit and is available in two overall lengths to suit different drilling depths.

Advantages

This Proline drill bit offers a consistent 16 mm hole size and is optimized for metal drilling. Its geometry and hardened cutting edges are intended to deliver reliable penetration and maintain edge life under typical metalworking conditions. Compatibility with common handheld drills and drill presses ensures flexible use across workshops and job sites. Availability in two lengths provides options for shallow and deeper drilling tasks.

Suitable for

• Drilling holes in sheet metal and thin steel plates
• Making bolt or clearance holes in construction and assembly work
• Use with handheld electric drills for on-site metalwork
• Use with drill presses in workshop settings for controlled, perpendicular holes

Key specifications

• Material application: metal (sheet metal, structural steel and similar alloys)
• Tip diameter: 16 mm for precise hole size
• Shank type: round shank compatible with standard drill chucks
• Available overall lengths: 400 mm and 600 mm to accommodate different penetration depths
• Quantity: single piece

How to use

Secure the drill bit in the chuck of a handheld drill or a drill press, ensuring the shank is properly centered and tightened. Mark the drilling point on the metal surface and, where appropriate, use a centre punch to prevent walking. Start drilling at low to moderate speed with steady pressure, using cutting fluid or lubricant to reduce heat and extend tool life when drilling thicker or harder metals. Withdraw the bit periodically to clear chips and maintain cutting efficiency. After completing the hole, deburr edges as required for a clean finish.

Usage recommendations

For best results, use appropriate cutting lubricant, match drill speed to the metal type and thickness, and choose the 400 mm length for standard-depth holes or the 600 mm length when additional reach is necessary. Inspect the bit before use and replace when wear reduces cutting performance.
