This 190mm saw blade has a 20mm bore making it suitable for both Makita and other brands of circular saws. The Deep Tooth design makes the blade especially tough and hard wearing. It is an ideal choice when dealing with reclaimed timber or cutting shuttering or very knotty timber. The blade can cope with the odd embedded nail or screw without damaging the teeth. Makita Specialised Blade: 190mm x 20mm x 40T, kerf 2mm.
