Drill bit Proline 22 mm x 600 mm model 92260 – metal drilling

Proline Drill Bit model 92260 is a single metal-cutting bit with a 22 mm diameter and 600 mm overall length, intended for long-reach drilling in metal. Designed for industrial and professional applications, this drill bit is made to be used with compatible drills and holders where deep-hole capability is required for tasks such as structural steelwork, pipe penetration and maintenance operations.

Advantages

The solid carbide insert is specially shaped to improve durability and maintain high cutting effectiveness during prolonged use. Accurate centered drilling reduces wandering and contributes to cleaner holes, while the double-twist flute design helps with faster chip evacuation and reduces load on the tool during penetration. These characteristics support consistent performance in demanding metal-drilling environments.

Suitable for

• Drilling through structural steel and thick metal plates
• Penetration of pipes and tubing in installation and maintenance work
• Long-reach or deep-hole drilling where standard-length bits are insufficient

Key specifications

• Diameter: 22 mm
• Overall length: 600 mm
• Intended material: metal
• Tip: solid carbide insert for metal cutting
• Flute design: double-twist for efficient chip removal
• Application level: industrial and professional use

How to use

Select a drill and holder rated to accept a 600 mm long, 22 mm diameter bit and ensure the chuck or collet secures the shank firmly. Mark the drilling point and, if needed, center-punch to help initial alignment. Use appropriate cutting speeds and feed rates for the metal being drilled, apply steady pressure and allow the double-twist flutes to clear chips. Maintain coolant or lubrication as required for the workpiece material to reduce heat and extend tool life.

Usage recommendations

Inspect the shank and carbide tip for damage before use, clamp the bit securely, and use suitable personal protective equipment. For best results in deep-hole metal drilling, use controlled speeds, intermittent withdrawal to clear chips if necessary, and cooling or lubrication to preserve cutting performance and tool life.
