## Summary description

Suitable for creating large-diameter holes in steel and other metals when used with compatible drills or drill presses. Intended for industrial or workshop applications requiring deep, wide holes.

## Long description

Proline 74037 metal drill bit is a single-piece drill designed for creating large-diameter holes in metal. The bit has a diameter of 40 mm and a total length of 370 mm, suitable for use with compatible hand drills, drill presses or magnetic drills in industrial and workshop environments. It is intended for drilling steel and other metal materials where a deep, wide hole is required and consistent cutting performance is needed.
Advantages
This drill bit is built as a single solid piece to provide stability during deep-hole drilling and reduce the risk of breakage. The 40 mm cutting diameter and 370 mm length allow for through-holes and deep recesses in thick metal sections. The cutting geometry and flute design promote chip evacuation and reduce heat buildup during prolonged use, supporting reliable performance in professional settings.
Suitable for
Making large-diameter holes in steel plates and metal sheets
Drilling through tubing, pipe walls and structural components
Workshop and industrial maintenance where deep holes are required
Use with drill presses, magnetic drills or heavy-duty hand drills
Key specifications
Material application: metal
Cutting diameter: 40 mm
Total length: 370 mm
Configuration: single-piece solid bit
How to use
Secure the drill bit in a compatible chuck or arbor rated for the bit diameter and the required torque. Clamp the workpiece firmly and align the drill perpendicular to the surface. Start at a low speed to establish the hole, then increase speed within the drill’s recommended range for metal cutting. Apply consistent, moderate feed pressure and periodically withdraw the bit to clear chips and reduce heat. Use appropriate cutting fluid for metal drilling to extend tool life and improve chip evacuation.
Usage recommendations
For safe and effective results, match drill speed and feed to the metal type and wall thickness, maintain secure fixturing, and use cooling or lubrication when drilling stainless or hard steels. Inspect the bit regularly for wear and replace if cutting performance deteriorates.
