Drill bit Proline 70516 — metal drill bit Ø5 mm, length 160 mm, 1 pc

Proline 70516 is a single metal drill bit with a 5 mm diameter and a total length of 160 mm. Intended for use in hand drills and drill presses, this straight-shank drill bit is designed for drilling metal and compatible materials during repair, fabrication and installation tasks. Supplied as one piece, it fits standard chucks and is suitable for professional and industrial applications.

Advantages

The Proline 70516 drill bit offers a long working length combined with a compact diameter, allowing access to deeper holes while maintaining control and stability. Its straight shank ensures secure mounting in common drill chucks. The construction supports efficient chip evacuation and consistent drilling performance in metal; the geometry is optimised to reduce walking at the start of the hole and to provide a steady cutting action.

Suitable for

• Drilling holes in metal sheets, plates and profiles
• Repair and maintenance tasks requiring precise 5 mm holes
• Fabrication and installation work with hand drills or drill presses
• Industrial and professional applications where a 160 mm length is needed

Key specifications

• Diameter: 5 mm
• Total length: 160 mm
• Shank type: straight shank for standard chucks
• Intended materials: metal and other suitable materials
• Quantity: 1 piece

How to use

Secure the Proline 70516 drill bit in the chuck of a hand drill or drill press, ensuring the shank is clamped firmly and concentric. Select an appropriate spindle speed and, if drilling metal, use cutting fluid or lubricant to extend tool life and improve chip removal. Start drilling with light pressure to establish the hole, then apply steady feed until the required depth is reached. Retract periodically if necessary to clear chips and prevent overheating.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Match drill speed and feed to the material being drilled; for harder metals use lower speeds and steady coolant application. Inspect the bit before use and replace it when wear or damage affects hole quality.
