Cutting Disc for Aluminium Irwin 125 mm x 1.6 mm x 22.23 mm

Flat cutting disc for aluminium by Irwin, 125 mm diameter, 1.6 mm thickness and 22.23 mm bore. Designed specifically for cutting aluminium and other non-ferrous metals on angle grinders, this thin disc enables precise, narrow kerf cuts with reduced material loss and minimal burr formation. The disc's profile and abrasive composition are optimized for clean, fast slicing of sheet metal, profiles and castings while maintaining consistent cutting performance during repetitive tasks.

Advantages

The Irwin Cutting Disc for Aluminium offers a thin 1.6 mm kerf for accurate cuts and less scrap, improving efficiency when trimming panels or preparing parts for assembly. Its formulation reduces clogging and heat buildup common when cutting soft metals, which helps preserve edge quality and prolong disc life under normal operating conditions. The 125 mm diameter provides a balance of cutting depth and manoeuvrability on standard angle grinders.

Suitable for

• Cutting aluminium sheet, plates and profiles
• Trimming and sizing non-ferrous metal components
• Workshop fabrication and on-site metal maintenance
• DIY projects involving aluminum window frames, gutters and trims

Key specifications

• Diameter: 125 mm
• Thickness (kerf): 1.6 mm
• Bore (arbor): 22.23 mm
• Type: Flat cutting disc for aluminium and non-ferrous metals
• Compatibility: For use with 125 mm angle grinders

How to use

Mount the disc on a compatible 125 mm angle grinder with a 22.23 mm arbor, ensuring the disc is correctly seated and the grinder is unplugged or the battery removed during installation. Tighten the clamping flange securely following the tool manufacturer's instructions. When cutting, run the grinder at the recommended speed, apply steady, even feed pressure and let the disc do the work without forcing. Use short, controlled passes for thin sheet metal to avoid deformation and to achieve a straight, clean cut. Replace the disc if it becomes worn, cracked or compromised.

Usage recommendations

Use appropriate personal protective equipment including eye and face protection, hearing protection and gloves. Secure the workpiece before cutting and avoid side-loading the disc. Allow the disc to cool between extended cuts to prevent overheating and changes in performance. Follow all safety and operating instructions for both the disc and the angle grinder.
