Why choose it

IRWIN's WIDIA line is built for professionals who demand durability and accuracy. The TCT teeth stay sharp longer than standard steel, reducing downtime for blade changes. The ATB grind produces a smooth finish on both crosscuts and rip cuts, while the expansion slots prevent warping under heat. This blade is a reliable workhorse for high-volume cutting of wood-based materials.

Ideal use cases

• Framing and general construction cutting of softwood and hardwood
• Cabinet making with plywood and MDF
• Flooring installation, including laminate and engineered wood
• Trim work and finish carpentry requiring clean edges

Good to know

The blade's 30 mm bore fits most standard table saws and miter saws, but always check your tool's arbor size before installation. For best results, ensure the blade is properly aligned and the workpiece is securely clamped. Regular cleaning of resin buildup will extend blade life and maintain cutting performance.
