Drill bit Proline 92030, metal, Ø20 mm, length 300 mm, 1 piece

Proline 92030 metal drill bit is a single-piece cutting tool with a 20 mm diameter and 300 mm overall length, intended for drilling through metal. The bit features a standard cylindrical shank for secure chuck clamping and is suitable for use with drill stands and handheld drills that accept long bits. It is designed for fabrication, maintenance and installation tasks where deep or through holes in steel and other metals are required.

Advantages

The solid one-piece construction ensures consistent concentricity and reliable transfer of torque during use. A standard shank allows fast, secure mounting in three-jaw chucks and drill stands. The 300 mm length enables drilling of deep or through holes without the need for extension accessories. The 20 mm diameter delivers a balance between hole size and material removal rate appropriate for many metalworking applications.

Suitable for

• Drilling through steel plates and structural metal components
• Creating deep holes in metal workpieces when using a drill press or long-reach handheld drill
• Maintenance, fabrication and installation tasks in workshops and construction sites
• Preparing holes for bolts, rivets or dowels in metal assemblies

Key specifications

• Material compatibility: metal (steel and similar metals)
• Diameter: 20 mm
• Overall length: 300 mm
• Shank type: standard cylindrical shank for chuck clamping
• Pack quantity: 1 piece

How to use

Secure the drill bit in a suitable chuck, ensuring the shank is fully inserted and clamped to minimize runout. Select an appropriate spindle speed and feed rate for the metal being drilled, and apply steady axial pressure. When drilling deep holes, periodically withdraw the bit to clear chips and allow cooling; use cutting fluid as needed to extend tool life and improve chip evacuation. For best results when precision is required, use a drill press or drill stand to maintain alignment.

Usage recommendations

Use suitable cutting fluid and moderate speeds when drilling hardened or stainless steels. Inspect the bit for wear or damage before use and replace if cutting edges appear dull or chipped. For safe operation, secure the workpiece and wear appropriate eye and hand protection.
