Drill bit Proline 72860, metal, Ø 28 mm, length 600 mm, 1 pc

Proline 72860 is a single solid drill bit engineered for metalworking tasks that require extended reach. With a 28 mm diameter and a total length of 600 mm, this drill bit is supplied as one piece and is intended for use with compatible drill rigs or magnetic drills. It is designed to produce through-holes and to assist with installation of large fasteners and other metal fabrication operations where a long-reach, rigid bit is required.

Advantages

The solid construction provides rigidity for deep drilling in steel and similar metals, while the 28 mm cutting diameter balances hole size with tool strength. The 600 mm overall length allows access to recessed or hard-to-reach areas without the need for extensions. Supplied as a single unit, the bit is ready for installation in appropriate chucks or holders and minimizes the risk of play or misalignment associated with multi-part extensions.

Suitable for (tasks / use cases)

• Deep drilling in steel and other ferrous and non-ferrous metals
• Creating through-holes for bolts, studs and large fasteners
• Metal fabrication and structural repair work requiring long-reach drilling
• Use with magnetic drills and drill rigs that accept long solid bits

Key specifications

• Material application: metalworking
• Cutting diameter: 28 mm
• Overall length: 600 mm
• Quantity: 1 piece

How to use

Install the Proline 72860 drill bit securely in a compatible chuck or arbor of a drill rig or magnetic drill that supports long solid bits. Ensure the workpiece is properly clamped and aligned. Select an appropriate cutting speed and feed rate for the metal being drilled, and use cutting fluid or coolant as recommended for the material to reduce heat and extend bit life. Apply steady pressure and allow the bit to clear chips periodically to prevent clogging during deep penetration.

Usage recommendations

For optimal performance, use the bit with a drill that provides stable clamping and supports the 600 mm length. Match cutting speed and coolant to the specific metal being drilled, and inspect the bit regularly for wear or damage when performing repeated deep drilling operations.
