Drill bit Proline 92040 — 20 mm diameter, 400 mm length, metal

Proline 92040 — 20 mm diameter, 400 mm length, metal. This single metal drill bit is designed for drilling metal with a 20 mm cutting diameter and 400 mm overall length. It is intended for use with handheld and stationary drills to create through-holes and perform sheet metal and fabrication tasks. The bit is supplied as one precision item suitable for professional and DIY metalworking applications.

Advantages

The Proline 92040 metal drill bit features a robust geometry that promotes accurate centered drilling and efficient chip evacuation. Its construction reduces load during operation, helping to maintain cutting performance over extended use. The 400 mm overall length provides extra reach for deep or hard-to-access holes while the 20 mm diameter delivers a standardized hole size for fittings and fasteners.

Suitable for

• Drilling through mild and hardened sheet metal
• Creating through-holes for bolts, rivets and anchors
• Fabrication and repair tasks in workshops
• Use with handheld and bench-mounted drills

Key specifications

• Cutting diameter: 20 mm
• Overall length: 400 mm
• Material type: metal drill bit (single piece)
• Application: metalworking, through-holes and sheet metal

How to use

Secure the Proline 92040 drill bit in the drill chuck tightening it according to the drill manufacturer's recommendations. Use appropriate drilling speeds and steady feed pressure for a 20 mm metal hole; reduce speed for harder metals and increase coolant or lubrication to extend tool life. Drill in a stable setup, clamp the workpiece, and clear chips regularly to maintain cutting efficiency and avoid overheating.

Usage recommendations

For best results when drilling metal, use cutting fluid or lubricant, clamp the workpiece securely, and start with a pilot hole if precise positioning or reduced cutting forces are required. Match drill speed and feed to the material hardness and inspect the bit for wear before use.
