You'll find hundreds of uses for these SANDING SLEEVES from KLINGSPOR'S WOODWORKING SHOP. Getting the desired smoothness on the edges of your workpiece or in a hole can sometimes be difficult. The same high quality material that goes into our premium belts is used in the making of our SANDING SLEEVES. Simply slide the sleeve over an expandable rubber drum with a 1/4" shank and you're ready to go. No gluing, no lapping, no worries.
