Diamond Cutting Blade Irwin 230 mm x 22.23 mm Segmented for Concrete, Brick, Granite, Marble

Irwin Diamond Cutting Blade 230 mm x 22.23 mm segmented blade is a purpose-built abrasive tool intended for cutting dense mineral materials. The blade's 230 mm diameter and 22.23 mm bore suit common angle grinders and construction saws with compatible arbors. Its segmented rim and diamond-impregnated cutting edge are designed to remove material efficiently and allow air flow to aid cooling during high-intensity cutting operations on concrete, brick, granite and marble.

Advantages

The segmented design balances rapid cutting speed with durability by combining diamond cutting segments and gullets that clear debris and reduce heat buildup. Compatibility with standard 22.23 mm arbors makes the blade convenient to mount on many angle grinders and site saws. The blade construction is intended to maintain consistent cutting performance on a variety of hard substrates while offering reasonable service life under typical construction and renovation workloads.

Suitable for

• Cutting reinforced and plain concrete panels and blocks
• Trimming and sizing clay and concrete brickwork
• Cutting granite and marble slabs for fabrication or installation
• On-site masonry and renovation work with angle grinders and handheld saws

Key specifications

• Diameter: 230 mm
• Bore (arbor) diameter: 22.23 mm
• Blade type: Segmented diamond rim
• Intended materials: Concrete, brick, granite, marble
• Compatible tools: Angle grinders and construction saws with matching arbor

How to use

Install the blade on a power tool with a 22.23 mm arbor, ensuring the blade is mounted in the correct rotational direction and tightened according to the tool manufacturer's torque recommendations. Use appropriate PPE including eye protection, hearing protection and dust control measures. Operate the tool at the recommended speed range for 230 mm diamond blades and apply steady, moderate feed pressure; avoid forcing the blade through the material. Periodically inspect the blade for wear, cracks or damage and replace it if any structural defects are present.

Usage recommendations

For best results on reinforced concrete, make shallow passes to establish a controlled cut and allow the blade to cool between heavy cuts. Use water cooling where the tool and jobsite conditions permit to reduce dust and extend blade life, and follow local safety guidelines for wet cutting.
