Drill bit Proline 70511 — metal drill bit Ø5 mm, length 110 mm, 1 pc

Single metal drill bit Proline 70511 with a 5 mm diameter and 110 mm overall length. Designed for drilling metal and similar materials, this straight-shank bit is supplied as one piece and fits standard drill chucks. Suitable for general metalworking, maintenance tasks and workshop use where a precise 5 mm hole is required.

Advantages

The Proline 70511 metal drill bit offers a consistent 5 mm hole size with a total length of 110 mm, providing extended reach compared with standard short bits. Its straight shank is compatible with typical chucks, enabling quick mounting and reliable concentric rotation. Supplied as a single unit, the bit is ready for immediate use and is intended for drilling in metal and comparable materials where straight, accurate holes are necessary.

Suitable for

• Drilling through steel sheets and metal plates
• Maintenance and repair tasks in workshops
• Creating precise 5 mm pilot holes for fastening
• General metalworking and machinery service

Key specifications

• Material compatibility: metals and similar hard materials
• Diameter: 5 mm
• Overall length: 110 mm
• Shank type: straight shank for standard drill chucks
• Quantity: 1 piece

How to use

Secure the drill bit in a compatible drill chuck, ensuring the shank is inserted fully and tightened. Mark the drilling position on the workpiece and, if necessary, clamp the piece to prevent movement. Start drilling at low speed to establish a center and then increase speed as appropriate for the metal being drilled; apply steady, moderate pressure and allow the bit to cut without forcing. Withdraw periodically to clear chips and reduce heat build-up. After completing the hole, remove burrs as needed for a clean finish.

Usage recommendations

Use cutting fluid or coolant when drilling ferrous metals to extend bit life and improve hole quality. Match drill speed to material hardness and avoid excessive axial force to prevent premature wear or breakage.
