Drill bit Proline 16 mm model 76616 for metal, 1 piece

Proline 16 mm drill bit model 76616 is a single metalworking cutter designed for creating precise 16 mm diameter holes in steel and other metals. Supplied as one piece compatible with standard drill chucks, this drill bit is intended for use in handheld drills and drill presses in workshop, maintenance, fabrication and construction settings. Available in two overall lengths (400 mm and 600 mm), it provides options for reaching varying hole depths and working through thicker materials.

Advantages

The Proline 16 mm drill bit offers a hardened cutting geometry engineered for metal drilling, delivering consistent hole diameter and good chip evacuation when used with appropriate speeds and lubrication. Its single-piece construction ensures stable centring and reduced runout in typical drilling setups. The availability of two lengths allows selection based on required reach or thickness of the workpiece, reducing the need for extensions or multiple tools.

Suitable for

• Drilling holes in mild and alloy steels
• Metal fabrication and sheet metal work
• Maintenance and repair tasks requiring 16 mm holes
• Construction and installation where metal components must be joined or fastened

Key specifications

• Cutting diameter: 16 mm
• Material compatibility: steel and other metals
• Shank type: compatible with standard drill chucks
• Lengths available: 400 mm and 600 mm overall length
• Quantity per pack: 1 piece

How to use

Secure the drill bit firmly in the chuck of a suitable handheld drill or drill press, ensuring correct seating and minimal runout. Select a drilling speed and feed appropriate for the workpiece material and bit diameter; lower speeds and steady feed are recommended for harder steels. Apply cutting fluid or lubricant to the drill point to reduce heat and improve chip flow. Start with a centre punch or pilot mark if precise placement is required, then drill steadily, withdrawing periodically to clear chips when drilling deep holes.

Usage recommendations

For best results, match drill speed and lubrication to the workpiece material, clamp the workpiece securely, and use coolant when drilling thicker or harder metals. Choose the 400 mm length for standard reach and the 600 mm length when deeper access or through-thickness drilling is needed.
