## Summary description

Proline 91080 metal drill bit, 10 mm diameter and 800 mm overall length, supplied as a single piece. Designed for drilling metal and other rigid materials where a long-reach straight twist bit is required. Suitable for workshop jobs, maintenance tasks and installations needing deep or hard-to-reach holes.

## Long description

Proline 91080 metal drill bit, 10 mm diameter and 800 mm overall length, supplied as a single piece. This long-reach straight twist bit is intended for drilling metal and other rigid materials where a deep or hard-to-reach hole is required. The design balances reach and rigidity to enable workshop, maintenance and installation tasks that need extended penetration while retaining centered drilling performance.
Advantages
The drill bit features a specially shaped solid carbide insert that increases durability and maintains cutting effectiveness under sustained loads. A double-twist flute design promotes fast chip evacuation and reduces drive load during penetration, contributing to consistent drilling speed and improved accuracy. The bit’s dimensions—10 mm diameter and 800 mm overall length—provide extended reach for deep holes while preserving axial stability for centered drilling.
Suitable for
Workshop drilling in metal components and structural elements
Maintenance and repair tasks requiring deep or hard-to-reach holes
Installation work where long-reach holes through rigid materials are needed
Drilling in concrete, granite and other natural stones when a carbide tip is required
Key specifications
Diameter: 10 mm
Overall length: 800 mm
Quantity: 1 piece
Tip material: solid carbide insert for durability and centered drilling
Flute geometry: double twist for efficient chip evacuation
Intended materials: metal, concrete, granite and other rigid materials
How to use
Select an appropriate drill holder or chuck that securely clamps the 10 mm shank and supports the extended length to minimize runout. Begin drilling at low speed to establish a centered start, then increase speed and feed according to the work material and machine capability. Use steady axial pressure without excessive side loads to preserve the carbide insert and maintain hole accuracy. For drilling in stone or concrete, employ a suitable hammer or rotary-percussion setting only if the tool and holder are rated for that mode; otherwise use rotary drilling with appropriate cooling or dust control.
Usage recommendations
For best results, ensure correct alignment and secure clamping of the long bit, use appropriate speeds and feeds for the work material, and remove chips frequently to prevent clogging. When working with abrasive or hard materials, monitor the carbide insert for wear and replace the bit when cutting performance declines.
