## Summary description

Proline 91860 metal drill bit with 18 mm diameter and 600 mm length. Single-piece set designed for drilling metal and similar hard materials.

## Long description

Proline 91860 metal drill bit with 18 mm diameter and 600 mm length is a single-piece, long-shank cutting tool designed for drilling metal and similarly hard materials. The bit is intended for use in hand drills and drill presses that accept long shank bits and is suitable for fabrication, maintenance and metalworking tasks where deep or through holes are required. The tool combines a solid construction with a geometry aimed at centered, controlled penetration and efficient chip evacuation.
Advantages
The Proline 91860 offers durable performance thanks to a specially shaped solid carbide insert that improves wear resistance and cutting stability. Its design delivers accurate centered drilling with reduced axial load and efficient material removal, while the extended 600 mm length enables drilling of deep holes or reaching recessed work areas. The single-piece configuration ensures consistent alignment and compatibility with machines that accept long shank bits.
Suitable for
Drilling through metal plates and structural components
Deep-hole drilling where standard-length bits are insufficient
Fabrication and maintenance tasks in workshops and industrial settings
Use with hand drills and drill presses that accept long shank drill bits
Key specifications
Material application: designed for metal and similar hard materials
Cutting insert: specially shaped solid carbide insert for improved durability
Diameter: 18 mm
Overall length: 600 mm
Construction: single-piece long shank design for stability and alignment
Flute type: double twist flutes for faster chip evacuation
How to use
Secure the Proline 91860 in a compatible drill chuck or press spindle ensuring the long shank is supported and centered. Select an appropriate spindle speed and feed rate for the workpiece material and carbide tip, and apply steady axial pressure to maintain centered drilling. Use cutting fluid when drilling metal to reduce heat and extend tool life. Withdraw periodically to clear chips when drilling deep holes, and recheck alignment and clamping before continuing.
Usage recommendations
For best results, match drill speed and feed to the metal type and thickness, use suitable cutting fluid, and ensure the machine and chuck can securely support the 600 mm long shank to avoid deflection and improve hole accuracy.
