## Summary description

Proline 72040 metal drill bit, single piece with 20 mm diameter and 400 mm overall length. Designed for drilling metal, this long-length twist bit suits through-holes and deep drilling tasks in steel and other metals.

## Long description

Proline 72040 metal drill bit is a long-length twist bit with a 20 mm cutting diameter and 400 mm overall length designed for drilling metal. This single-piece bit is intended for through-holes and deep drilling tasks in steel and other metals where extended reach and straight, consistent holes are required. The geometry and flute design support chip evacuation during deep cuts and help maintain drilling accuracy when used with compatible chucks and power drills.
Advantages
The 20 mm diameter and 400 mm length provide extended reach for deep or hard-to-access drilling without the need for extensions. The double-twist flute geometry improves chip removal and reduces clogging during prolonged drilling. A hardened cutting edge and optimized point angle ensure consistent performance in steel and typical construction metals. Supplied as a single unit, the bit is ready for immediate use in fabrication, repair and installation tasks.
Suitable for
 Drilling deep through-holes in steel sheets and metal plates
 Accessing recessed or hard-to-reach fastening points
 Fabrication and repair work in workshops and on-site
 Installation tasks requiring extended reach for bolts and anchors
Key specifications
 Cutting diameter: 20 mm
 Overall length: 400 mm
 Material application: metal (steel and similar alloys)
 Flute type: double-twist for improved chip evacuation
 Unit quantity: 1 piece
How to use
Secure the drill bit in a compatible chuck rated for the bit diameter and the drill's torque. Mark and center-punch the drilling point on the workpiece to reduce wandering. Start drilling at low speed to establish the hole, then increase speed as appropriate for the metal thickness and the drill's specifications. Use steady, moderate pressure and withdraw the bit periodically to clear chips and reduce heat buildup. Apply cutting fluid or coolant for improved cutting performance and longer bit life when drilling harder steels.
Usage recommendations
For best results, use the bit with a drill that can deliver stable RPM and torque for metalworking. Match feed rate and speed to material thickness; use cutting lubricant when drilling stainless steel or higher-alloy materials. Inspect the bit for wear before extended use and replace when cutting edges show signs of dulling to maintain hole quality and reduce risk of breakage.
