Drill bit Proline 26828, metal, Ø28 mm, length 230 mm, 1 pc

Proline 26828 drill bit is a single metalworking bit designed for creating large-diameter holes in metal components. With a nominal diameter of 28 mm and an overall length of 230 mm, this bit is intended for use in applications such as pipework, sheet metal and structural parts where a clean, sizable bore is required. The bit is supplied as one piece and is compatible with drill drivers and holders that accept its shank type.

Advantages

The drill bit features a geometry optimized for metal drilling and a threaded guide blade to assist in advancing through the workpiece with reduced walking. The hexagonal shank provides secure grip and torque transmission in compatible chucks or bit holders. Supplied in a plastic case, the bit is protected during storage and transport.

Suitable for

• Drilling large holes in thin and thick metal sheets
• Creating access holes for pipework and conduit installations
• Preparing openings in structural metal components and frames
• Use with drill drivers and holders that accept hexagonal shanks

Key specifications

• Diameter: 28 mm
• Overall length: 230 mm
• Shank type: hexagonal
• Guide: threaded guide blade for self-feeding
• Delivery: single piece in a plastic case

How to use

Mark the drilling position and secure the workpiece to prevent movement. Fit the Proline 26828 drill bit into a compatible drill driver or holder, ensuring the hexagonal shank is fully engaged and tightened. Start drilling at low speed to allow the threaded guide blade to engage, then increase speed and apply steady pressure appropriate to the metal thickness. Withdraw periodically to clear chips and avoid overheating. Use suitable cutting fluid when drilling thicker or harder metals to extend tool life and improve cutting performance.

Usage recommendations

Use appropriate personal protective equipment, including eye protection and gloves. Select drill speeds and cutting fluids suitable for the specific metal being drilled, and avoid excessive side load to prevent bit breakage. Store the bit in its plastic case when not in use to protect the cutting edges.
