YS575 - Sic Supreme Belts are designed for back roughening of laminates and calibrating medium to fine sanding of particle boards. Featuring a Silicon Carbide grain and heavy polyester backing, these belts ensure a uniform scratch pattern throughout the belt life with minimal premature grain fracturing. The semi-open coat helps reduce clogging, while the robust construction withstands high grinding pressures, making them ideal for use on high-speed machines.
