Cutting Disc for Metal Irwin 230 mm x 1.8 mm x 22.23 mm

Flat cutting disc for metal Irwin 230 mm x 1.8 mm x 22.23 mm is designed for abrasive cutting of steel and other metallic materials on angle grinders. The disc features a 230 mm diameter and 1.8 mm cutting thickness, with a 22.23 mm centre hole for secure mounting. It is intended for straight, fast cuts in metalwork, fabrication and repair tasks when used with the appropriate guard, speed limits and personal protective equipment.

Advantages

The thin 1.8 mm cutting profile minimises material loss and reduces grinding time while delivering a precise cut. Designed for high cutting performance on steel and common metal alloys, the disc balances durability and cutting speed to support repetitive industrial and workshop use. The standard 22.23 mm bore ensures compatibility with most angle grinders when fitted with the correct flange and guard.

Suitable for

• Cutting steel sheet, bars and profiles
• Fabrication and metal assembly tasks
• Workshop and on-site repair work on metal components
• Removal of rivets, bolts and fasteners where a thin kerf is required

Key specifications

• Disc diameter: 230 mm
• Cutting thickness: 1.8 mm
• Centre bore diameter: 22.23 mm
• Application material: steel and common metal alloys
• Tool compatibility: angle grinders with matching arbor and suitable guard

How to use

Fit the disc to an angle grinder with the correct flange and tighten according to the tool manufacturer’s instructions. Verify the grinder’s no-load speed does not exceed the disc’s maximum permitted RPM before starting. For effective cutting, steady the workpiece and use a straight cutting motion with light to moderate pressure; avoid twisting the disc in the cut. Always use the grinder’s protective guard, and allow the disc to cool between prolonged cuts to preserve its abrasive properties.

Usage recommendations

Wear eye protection, gloves, hearing protection and suitable respiratory protection. Do not use the disc for grinding or on materials other than those specified. Replace the disc if cracked, chipped, or excessively worn. Follow the angle grinder and disc safety instructions for mounting, speed limits and permitted operating positions.
