Drill bit Proline 72060, metal, Ø20 mm, length 600 mm, 1 pc

Proline drill bit 72060 is a metalworking drill bit with a 20 mm diameter and 600 mm overall length, supplied as a single piece. Designed for drilling metal, this drill bit is suitable for creating deep or extended holes in structural components, fixtures and sheet or plate materials where long reach is required. It is intended for use with compatible drills and appropriate cutting fluid to maintain tool life and hole quality.

Advantages

The drill bit features a double-twist design that facilitates faster chip evacuation and reduces clogging during deep drilling operations. A multi-flute cutting geometry improves cutting stability and helps maintain hole straightness over the full 600 mm length. Supplied as one piece, the solid construction provides rigidity for extended-reach drilling tasks and is compatible with standard metalworking drill setups.

Suitable for

• Drilling deep or hard-to-reach holes in metal components
• Fabrication and structural work requiring extended-reach drilling
• Fixture and jig preparation where long-length holes are needed
• General metalworking tasks on steel and non-ferrous metals

Key specifications

• Material application: metalworking
• Diameter: 20 mm
• Overall length: 600 mm
• Quantity in pack: 1 piece
• Design features: double-twist geometry and multi-flute cutting insert for chip removal

How to use

Secure the workpiece and use an appropriate drill or drilling setup capable of accommodating a 600 mm length bit. Clamp the drill bit correctly in the chuck or holder to minimise runout and ensure axial alignment. Apply a suitable cutting fluid or coolant for metal drilling and start at low speed to establish the pilot hole, then adjust speed and feed rate according to material and drill manufacturer recommendations. Retract periodically if necessary to clear chips and maintain cutting performance.

Usage recommendations

For best results, use with compatible drills rated for extended-reach bits, maintain steady feed, and use cutting fluid to reduce heat and wear. Inspect the bit for wear before use and replace when cutting performance degrades.
