With the Fein sanding belt abrasive R, you achieve heavy stock removal on stainless steel and high-alloy steel. Thanks to coarse 36 grit and tough zirconium oxide, you can grind down heavy weld seams and remove stubborn burrs quickly and effortlessly. An additional top layer reduces heat buildup during grinding, protecting your workpieces from thermal discolouration. The tear-resistant backing made of extra-heavy polyester fabric ensures excellent stability and durability under high contact pressure. This 10-pack of 150 x 2250 mm sanding belts is designed for stationary belt grinding machines such as the Fein Grit gir and gi 150 units.
