This 130mm diameter Irwin Construction Circular Saw Blade features 20 teeth and a 20mm bore, making it suitable for handheld corded saws requiring slightly larger blade diameters. The 20-tooth configuration strikes a balance between cutting speed and finish quality, providing efficient performance across a variety of wood cutting applications. Construction-grade tungsten carbide tips retain their sharpness throughout demanding job site conditions, whilst the fully hardened plate ensures consistent accuracy. Expansion slots integrated into the blade design dissipate heat effectively, preventing warping during extended cutting sessions. The alternate top bevel (ATB) tooth grind excels at both cross-cutting and ripping operations in all wood types. The corrosion-resistant coating protects the blade surface and maintains cutting performance over time. This blade is specifically designed for use with handheld corded circular saws equipped with a 20mm arbor.
