Hand saw Irwin 10505542, blade length 55 cm, blue/yellow handle

Irwin XPERT 550 mm (22") circular saw blade with hardened coarse teeth, 8T, is designed for heavy-duty ripping and fast material removal in woodworking and construction. The large 550 mm diameter and low tooth count provide aggressive cutting action and high feed rates when used on compatible circular saws. This blade is intended for ripping boards, beams and similar timber where rapid throughput and efficient chip clearance are priorities.

Advantages

The hardened coarse teeth extend wear resistance when cutting soft and hardwoods and reduce the need for frequent re-sharpening. A low-tooth geometry improves chip evacuation and minimizes clogging during deep cuts, while the robust blade body maintains flatness and stability at high rotational speeds. The combination of diameter and tooth design enables fast linear feed and efficient removal of material with fewer passes.

Suitable for

• Ripping softwoods and hardwoods into boards and planks
• Crosscutting of large timber when aggressive material removal is required
• Construction site sawing of beams and dimensional lumber
• Portable or stationary circular saws rated for 550 mm blades

Key specifications

• Diameter: 550 mm (22")
• Tooth count: 8 teeth (coarse geometry)
• Tooth material: hardened cutting edges for increased wear resistance
• Design purpose: aggressive ripping and fast material removal
• Suitable materials: softwood, hardwood, construction timber

How to use

Install the blade on a compatible circular saw following the machine manufacturer's instructions and ensuring the arbor size and mount match. Secure the blade tightly, confirm correct rotation direction, and set appropriate cutting depth. For safe operation, use steady feed rates suitable for coarse teeth: do not force the blade but allow it to cut at its designed aggressive feed. Wear appropriate personal protective equipment and follow all site safety rules.

Usage recommendations

For best results, use this Irwin XPERT 550 mm coarse-tooth blade for long rip cuts and bulk removal tasks rather than fine finishing. Check blade mounting and saw RPM compatibility before each use, and inspect teeth for wear or damage after extended cutting sessions. Avoid cutting materials with embedded metal fasteners to preserve the hardened cutting edges.
