The iQ Power Tools 16-1/2" Q-Drive Arrayed Segmented Super Hard Concrete Purple Blade (MASQX16-125-QD-HM3) incorporates the latest in diamond tool technology. The iQ arrayed diamonds make for faster, more consistent cutting speeds. When one row of diamonds begins to wear out, there is a second row right behind it that’s ready to cut. This Q-Drive blade is designed specifically for the iQMS362 and cuts up to 40% faster than other masonry blades. It cuts a wide variety of masonry, concrete, and stone products with precision cuts that match the quality of a wet blade.
