## Long description

Proline 73072 is a single 30 mm diameter drill bit with an overall length of 720 mm designed for long-reach drilling in metal and other hard materials. The tool is supplied as one piece and is intended for workshop, maintenance and industrial applications where extended or deep holes are required. The drill's geometry and construction support drilling in demanding conditions while maintaining stability over its extended length.
Advantages
The Proline 73072 drill bit combines a 30 mm cutting diameter with a 720 mm length to enable deep and extended-reach holes without the need for extensions. A double-twist design aids rapid dust removal from the cut, and a 4-blade insert with optimised geometry improves cutting consistency and stability. Supplied as a single unit, it is ready for immediate use in drills and rigs compatible with its shank type.
Suitable for
 Workshop and maintenance tasks requiring deep or hard-to-reach holes
 Industrial fabrication and assembly where long-reach drilling is needed
 Drilling in metal and other hard materials
 Applications that benefit from fast dust evacuation during drilling
Key specifications

 Overall length: 720 mm

How to use
Select an appropriate drilling machine or rig that accepts the drill bit shank and secure the bit firmly in the chuck or collet. Mark the drilling point and, if required, use a centre punch to prevent bit wandering. Start drilling at low speed to establish the hole, then increase speed and maintain steady feed pressure appropriate for the workpiece material. Monitor chip removal and, when drilling deep holes, withdraw the bit periodically to clear accumulated chips and prevent overheating. Use suitable cutting fluid or coolant when drilling metal to extend tool life and improve performance.
Usage recommendations
For best results, match drill speed and feed to the material being drilled, use appropriate coolant for metalworking, and ensure the drilling machine is rigid and properly aligned to reduce bit deflection over the 720 mm length.
