This 160mm diameter Irwin Construction Circular Saw Blade features 30 teeth and a 20mm bore, offering enhanced finish quality for applications requiring cleaner cuts. The higher tooth count makes this blade well-suited for finish carpentry, cabinetry and trim work, whilst retaining the durability needed for general construction tasks. Construction-grade tungsten carbide tips ensure the blade maintains its cutting edge through repeated use. The fully hardened plate provides consistent accuracy and durability, whilst expansion slots effectively dissipate operational heat to prevent warping. The alternate top bevel (ATB) tooth grind delivers excellent results when cross-cutting and ripping in all wood types. A corrosion-resistant coating protects the blade surface and maintains cutting performance over extended periods. This blade is designed for handheld corded circular saws with a 20mm arbor.
