Drill bit Proline 72660, metal, Ø26 mm, length 600 mm, 1 pc

Proline 72660 is a single metalworking drill bit with a 26 mm diameter and a total length of 600 mm, intended for drilling metal with hand-held and stationary drills. The long reach of this bit enables drilling of deep or through holes in fabrication, repair and installation tasks where a large-diameter metal hole is required. The design targets industrial and professional applications that need a robust, long-reach solution for metal drilling.

Advantages

The Proline 72660 drill bit combines a 26 mm cutting diameter with a 600 mm overall length to provide access to deep workpieces and hard-to-reach locations. Its construction is aimed at metalworking: the geometry supports efficient chip evacuation for extended drilling depths and reduces binding in through-hole operations. Supplied as a single piece, it is compatible with standard chucks on portable and bench drills used in fabrication and maintenance workflows.

Suitable for

• Drilling deep or through holes in steel and other metals
• Fabrication and metalworking where long-reach holes are needed
• Repair and maintenance tasks on machinery and structural components
• Installation work requiring large-diameter metal openings

Key specifications

• Material application: metal
• Cutting diameter: 26 mm
• Overall length: 600 mm
• Quantity in pack: 1 piece
• Suitable for use with hand-held and stationary drills

How to use

Secure the Proline 72660 drill bit in a drill chuck rated for the bit diameter and the torque expected during metal cutting. Mark the drilling location and, if appropriate, use a centre punch to prevent walking. When drilling, start at low speed to establish the hole, then increase speed and apply steady feed pressure appropriate for the workpiece material. Use cutting fluid or coolant to reduce heat and extend bit life, and withdraw the bit periodically to clear chips when drilling deep holes.

Usage recommendations

For best results when drilling metal with the Proline 72660, use a suitable cutting fluid, maintain correct speed and feed for the material, and ensure the drill and chuck provide stable alignment. Inspect the bit for wear before use and replace if cutting performance deteriorates.
