Drill bit Proline 72292, metal, Ø22 mm, length 920 mm, 1 pc

Proline 72292 is a single metalworking drill bit with a 22 mm diameter and a 920 mm length, supplied as one piece for tasks requiring extended reach. Designed for drilling metal, this long-sized bit fits drills that accept large-diameter, long shanks and is intended for professional or heavy-duty metal drilling where through-holes or deep penetration are needed.

Advantages

The Proline 72292 drill bit offers a long working length that enables drilling of deep or hard-to-reach metal components without repositioning the workpiece. Its 22 mm cutting diameter provides a stable hole size for fittings and fasteners. The single-piece design reduces the risk of joint failure and simplifies setup, while compatibility with standard heavy-duty drills ensures use in industrial and workshop environments.

Suitable for

• Drilling through metal plates and structural steel
• Creating deep holes in machine parts and assemblies
• Workshop and industrial maintenance requiring extended-reach drilling
• Applications where a single, long-diameter bit is preferred over extensions

Key specifications

• Material application: metalworking
• Diameter: 22 mm
• Overall length: 920 mm
• Quantity in package: 1 piece

How to use

Secure the drill bit in a compatible heavy-duty drill or drill press that can accept long, large-diameter bits. Clamp the workpiece firmly and mark the drilling point. Start at a low speed to establish the pilot and increase speed as appropriate for the material and drill capacity. Apply steady, even pressure and allow the bit to cut without forcing. Retract occasionally to clear chips if necessary and use cutting fluid when drilling harder metals to reduce heat and extend tool life.

Usage recommendations

Use appropriate personal protective equipment, secure long workpieces to prevent movement, and ensure the drill spindle and chuck are rated for the bit's length and diameter. For best results on hard metals, use cutting lubricant and moderate drilling speeds; avoid excessive side loads to preserve the bit geometry.
