## Long description

Proline 72837 is a single metal drill bit designed for drilling metal with a 28 mm diameter and 370 mm overall length. Manufactured for use with hand drills and drill presses, this long-reach bit is suitable where larger-diameter holes or through-holes are required in fabrication, metalworking and maintenance tasks. The product is supplied as one piece and is intended for professional and industrial applications that require a robust cutting tool for metalworking.
Advantages
The drill bit features a 28 mm cutting diameter combined with a 370 mm overall length to reach recessed or deep sections without extensions. Its geometry is optimised for metal drilling to provide efficient chip evacuation and steady cutting action when paired with appropriate speeds and coolant. The single-piece construction reduces flex and helps maintain concentricity during use, while compatibility with standard chucks allows use in both portable and stationary drilling equipment.
Suitable for
Drilling large-diameter holes in steel and other metals
Fabrication and assembly work requiring through-holes or clearance openings
Maintenance and repair tasks on machinery and metal structures
Use with hand drills and drill presses where long reach is needed
Key specifications
Material suitability: metals (steel and similar ferrous/non-ferrous materials)
Cutting diameter: 28 mm
Overall length: 370 mm
Quantity: 1 piece
Intended use: hand drills and drill presses
How to use
Secure the drill bit in a compatible chuck ensuring correct seating and tight clamping. Select a drilling speed appropriate for the metal being worked; slower speeds are generally recommended for larger diameters and harder materials. Use a steady feed rate and, where applicable, cutting fluid or coolant to reduce heat and improve chip evacuation. If drilling deep holes, withdraw periodically to clear chips and reapply coolant as needed. Inspect the bit regularly for wear and replace it when cutting performance degrades.
Usage recommendations
For best results, match drilling speed and feed to the specific metal type, use appropriate cutting fluid, and ensure the drill and workpiece are securely clamped. When accessing deep or confined areas, verify chuck clearance and maintain steady pressure to avoid wandering or overheating. Store the bit in a dry place to prevent corrosion.
