Diablo's 1/2 x 18 in detail file sanding belts include break-through innovations that improve performance, extend sanding life and increase productivity. Featuring a premium aluminum oxide blend, these belts remove material faster than other sanding belts and offer an extra-long sanding life. The stearate coating reduces build-up while the premium joint connection ensures the belt can withstand a variety of sanding applications such as heavy stock removal, planing and sanding. Clog-SHIELD?, Diablo's own blend of grinding agents, reduces loading while the excellent grain bonding system, ENDURA-BOND?, delivers longer life and extreme durability.
