About this product
A 190mm circular saw blade for portable saws, designed for first-fix construction work where cut finish matters less than speed and durability. It suits rough timber, softwoods and composites, including re-used or reclaimed wood that may contain embedded nails, thanks to impact-resistant carbide teeth and a wedge shoulder that protects the carbide from nail strikes.
The blade has 40 teeth with Alternate Top Bevel (ATB) grind and a +10° rake angle for a fast, smooth cut with reduced splintering. Ribbed heat vents help keep the blade running cooler, reducing flexing and binding. Bore size is 30mm, plate thickness 1.7mm and kerf thickness 2.6mm, with a 5/8" arbor and diamond knock-out for fitting to different machines.
