Drill bit Proline 92226 — metal drill bit Ø22 mm, length 260 mm, 1 pc

Proline 92226 is a single solid drill bit for metalworking with a nominal diameter of 22 mm and an overall length of 260 mm. The bit is supplied as one piece and is intended for drilling metal sheets, profiles and structural steel. It is suitable for use in hand-held drills and drill presses provided the chuck and rotational speed are appropriate for the diameter and material being worked. The design emphasises centered, accurate drilling and is intended for repair, fabrication and industrial maintenance tasks.

Advantages

The Proline 92226 drill bit features a solid construction that provides mechanical stability when drilling into metal. A specially shaped solid carbide insert increases wear resistance and maintains cutting performance over extended use, helping to deliver accurate centered holes. Its geometry reduces axial load and supports efficient chip evacuation for longer continuous operation. The product is supplied as a single unit, making it suitable for targeted replacements or one-off jobs.

Suitable for

• Drilling holes in metal sheets and thin plate
• Working with metal profiles and structural steel
• Repair and maintenance tasks in workshops and industrial settings
• Fabrication tasks requiring precise, centered holes

Key specifications

• Diameter: 22 mm
• Overall length: 260 mm
• Material type: solid drill bit with carbide cutting insert
• Geometry: double twist for effective chip removal
• Pack: 1 piece

How to use

Secure the drill bit in an appropriate chuck that accepts the shank and ensures concentric clamping. Select a drill speed suitable for a 22 mm metal drill (lower RPMs for harder steels) and apply steady feed pressure without forcing the bit. Use cutting fluid or lubricant as appropriate for metalworking to improve cutting performance and tool life. Clear chips from the hole periodically during deeper drilling to avoid clogging and overheating. After use, clean and store the bit in a dry place to prevent corrosion.

Usage recommendations

Use the Proline 92226 drill bit with compatible drilling equipment rated for large-diameter metal drilling, and match speed and coolant to the workpiece material. For improved life and hole quality, employ proper lubrication and intermittent drilling technique when penetrating thick or hard metal sections.
