Drill bit Proline 71626, metal, Ø16 mm, length 260 mm, 1 pc

Proline 71626 is a single metal drill bit with a 16 mm diameter and a total length of 260 mm, intended for drilling holes in metal. The solid cylindrical shank and twist design make it suitable for use in hand-held electric drills and drill presses when larger clearance holes or preparation for fastening and machining are required. The bit is supplied as one piece and is positioned in the Drill Bits category under the Proline brand.

Advantages

The Proline 71626 drill bit is manufactured for metalworking tasks where a reliable 16 mm hole is needed. Its twist geometry promotes efficient chip evacuation and stable drilling, while the overall length provides reach for thicker workpieces or setups in press and stand-mounted drilling machines. The single-piece construction reduces the risk of joint failure and simplifies fitting in standard drill chucks.

Suitable for

• Creating clearance holes in steel and non-ferrous metals
• Preparing metal parts for fastening or assembly
• Use in hand drills and drill presses for medium-depth holes
• Workshop and light industrial metal fabrication tasks

Key specifications

• Material application: metal
• Diameter: 16 mm
• Total length: 260 mm
• Supply quantity: 1 piece
• Compatibility: suitable for hand-held electric drills and drill presses

How to use

Secure the workpiece in a vise or with clamps to prevent movement. Install the Proline 71626 drill bit in a compatible drill chuck and tighten securely. Select an appropriate spindle speed and cutting fluid for the metal being drilled to prolong tool life and improve chip evacuation. Apply steady pressure and start drilling at low speed to establish the hole, then increase speed as appropriate while maintaining coolant and chip clearance. Withdraw the bit periodically to clear chips on deeper holes.

Usage recommendations

For best results, use cutting oil when drilling steel and slower speeds for harder alloys. Ensure the drill chuck is rated for the bit diameter and maintain consistent feed to avoid overheating. Inspect the bit for wear and replace if the cutting edges show rounding or chipping.
