Drill bit Proline 26638, metal, Ø 38 mm, length 150 mm, 1 pc

Single Proline 26638 metal drill bit with a 38 mm diameter and 150 mm overall length. Designed for drilling through metal and heavy materials, this solid one-piece bit is intended for workshop and industrial use where large-diameter holes are required. The tool features a ground point and cutting blade for precise centering and stable cutting performance; it is supplied with a hexagonal shank and packaged in a protective plastic case.

Advantages

The ground center point improves accuracy on contact and reduces wandering when starting holes, while the robust blade geometry supports clean chip removal in thicker materials. The hexagonal shank ensures secure clamping in chucks or holders designed for hex drives and reduces slippage during high-torque operations. Being a single solid piece, the drill bit offers consistent concentricity and durability in repeated heavy-duty use.

Suitable for

• Drilling large-diameter holes in metal plates and structural steel
• Creating openings for pipes, conduits or fasteners in workshop settings
• Industrial maintenance and fabrication tasks requiring precise centering

Key specifications

• Material suitability: metal and heavy workpieces
• Diameter: 38 mm
• Overall length: 150 mm
• Shank type: hexagonal
• Point and blade: ground center point with cutting blade for precise centering and effective chip evacuation
• Packaging: supplied in a protective plastic case

How to use

Select a drill or holder compatible with a 38 mm bit and hexagonal shank, and ensure the machine’s power and chuck capacity are suitable for heavy-duty drilling. Secure the workpiece, mark the drilling position, and start at low speed to engage the ground center point for accurate centering. Apply steady pressure and reduce speed as needed when cutting thicker or harder metal to avoid overheating. Clear chips periodically and use appropriate cutting fluid for metal to extend bit life and improve hole quality.

Usage recommendations

Use appropriate personal protective equipment, clamp workpieces securely, and confirm that the drill and holder are rated for the bit diameter and expected torque. For prolonged drilling or hard metals, use cutting fluid and moderate speeds to maintain cutting performance and reduce wear.
