Magnate Z4X36S10 4" x 36" Sanding Belt - Zirconia Alumina - 100 Grit; Y Weight; 1 Belts/Pkg; Resin Bond Polyester Backings; Closed Coat

This closed coat zirconia alumina belt uses a heavy "Y" weight resin bond polyester backing with grinding aid for a fast cut in heavy grinding, deburring applications. It is suitable for cast iron, nickel, alloy and stainless steel requiring sharp cutting without heat build-up.. Closed Coat Abrasive Grain Coverage - Abrasive grains cover 100% of the coated surface. The greater number of abrasive grains normally results in a better finish and a higher amount of stock removal during the useful life of the product. If loading is not a problem, a Closed Coat product will give you superior life and lower cost. Closed Coat products are widely used in metalworking and woodworking applications. Resin Bond Backings - Resin bond backings offer greater resistance to heat , are more durable in heavy stock removal applications and provide the best all-around bond system. Zirconia alumina is a man made abrasive and its products are typically in green or blue color. A blocky shape grain has a micro-crystalline structure. Zirconia alumina's self-sharpening characteristic gives good life on heavy stock removal applications, i.e. heavy grinding of metals, planing operations for wood.
