Blazer Pro Diamond Hole Saw Size 1'' for Porcelain Tile, Ceramic Tile, Marble, Granite, Glass, Terrazzo, Quartz and Other Hard Surfaces, Metal Bonded Bits for Longer Life (1'')

Blazer diamond hole saws for drilling holes in hard porcelain tile, glass tile, ceramic tile, marble, granite, slate, limestone, terrazzo, quartz and any similar materials. Produce clean and accurate holes in minutes with little or no chipping! May be used for dry or wet drilling. Sizes 1/2"-7/8" do not have a pilot bit in the center and we suggest using a piece of wood as a template. Because this is a top-quality US made product it is backed with a 100% lifetime warranty that also includes free return shipping. If it ever breaks, warps, cracks or shows any sign of a material defect (being used for its intended purpose), or if the bond between the diamond segment and the steel core becomes separated at any time, it will be replaced free of charge!
