Drill bit Proline 26928, metal drill bit Ø28 mm, length 460 mm, 1 pc

Proline 26928 is a single metal drill bit with a 28 mm working diameter and a total length of 460 mm. Designed primarily for drilling metal, the bit features a long reach suitable for bench or portable drills that can accommodate its diameter and length. The package contains one piece in a plastic case and the tool is intended for creating larger holes in sheet metal, plates or structural steel where a substantial bore and extended length are required.

Advantages

The drill bit offers a large 28 mm diameter for creating substantial holes and a 460 mm overall length for extended reach in deep or hard-to-access locations. Its construction is intended for metal drilling, and the supplied plastic case protects the bit during storage and transport. The product is a single-piece solution that is simple to fit into compatible drills and handle one-off or repeated larger-diameter metal drilling tasks.

Suitable for

• Drilling holes in sheet metal and metal plates
• Creating larger-diameter holes in structural steel
• Applications requiring long-reach drilling in metal
• Use with bench drills and portable drills that accept large-diameter bits

Key specifications

• Diameter: 28 mm
• Total length: 460 mm
• Material suitability: metal (sheet, plate, structural steel)
• Package contents: 1 drill bit in a plastic case
• Shank type: hexagonal shank

How to use

Install the drill bit into a compatible drill chuck or hexagonal holder according to the drill manufacturer's instructions, ensuring the shank is fully seated and secured. Clamp the workpiece securely and mark the drilling point. Start at low speed to establish the pilot, apply steady pressure and increase speed as appropriate for the material. Use cutting fluid or coolant for metal drilling to extend bit life and reduce heat. After completing the hole, retract the bit carefully while the drill is running at low speed to clear chips, then stop the drill before removing the bit from the chuck.

Usage recommendations

Use appropriate personal protective equipment, such as safety glasses and gloves, and ensure the drill and workpiece are properly secured. Maintain moderate feed pressure and apply cutting fluid when drilling metal to reduce heat and prolong bit life. Verify that the drill and chuck can safely accept a 28 mm diameter bit and the 460 mm length before use.
