Diamond contour blades are used most often by fabricators to cut out round and oval sink holes in granite and marble countertops. Concave type core makes these blades ideal for cutting circular openings; such as sink holes and curve type cuts. This new design has segments which extend lower and protrude outward to prevent binding. Great for use on concrete. Used with circular saws or small right-angled Grinders. Marble / Limestone contour blade uses electroplated technology. For straight cuts use our Premium Granite Blades.
