Drill bit Proline 71080 — metal drill bit Ø10 mm, length 800 mm, 1 pc

Proline 71080 is a metal drill bit with a 10 mm diameter and an overall length of 800 mm, supplied as a single piece. It is intended for drilling metal and other solid materials where extended reach is required. The bit is designed to be used with drills or drill chucks that accommodate long bits and is suitable for deep-hole drilling, maintenance and fabrication tasks. The manufacturer does not specify shank type or material.

Advantages

The extended 800 mm length provides access to deep or hard-to-reach drilling locations without the need for extensions. A 10 mm cutting diameter balances rigidity and hole size common in metalworking tasks. The single-piece supply simplifies selection and inventory for specific long-reach applications. The design supports use in tasks that require sustained straight drilling over an extended reach.

Suitable for

• Deep-hole drilling in metal components
• Maintenance and repair tasks where reach is limited
• Fabrication and assembly requiring long-reach holes
• Situations requiring a 10 mm hole diameter with extended length

Key specifications

• Diameter: 10 mm
• Overall length: 800 mm
• Quantity: 1 piece
• Intended material: metal (manufacturer specified)

How to use

Fit the Proline 71080 drill bit into a compatible drill chuck that can securely hold long bits and is rated for the required drilling speed and torque. Ensure the workpiece is clamped firmly and aligned with the intended drilling axis. Begin drilling at moderate speed and apply steady, even pressure to avoid bit flexing; for deep holes, periodically withdraw the bit to clear chips and reduce heat buildup. Follow the drill and workshop safety guidelines, including eye protection and appropriate gloves.

Usage recommendations

Use a drill or chuck designed for long bits and select appropriate cutting speed and lubrication for the metal being drilled. Regularly clear chips during deep-hole operations to maintain cutting efficiency and reduce wear. Because the manufacturer does not specify shank type or material, confirm compatibility with your drill before use.
