Purchased for use on a Makita 4 1/2 grinder (model not sure) which was not an SJS as Makita claims is the only model designed for a sheath. It fitted the grinder perfectly, but to get a comfortable working position I had to cut an extra mounting groove in the aluminum case where the protective cover attaches. With all that, when hooked up to a grinder and shop vacuum, there was literally no dust visible when cutting a concrete block. Haven't used it on the stovetop yet, but I'm sure the result will be the same.
