    1. Great sanding belt

      Have always had great success with Empire products. on Oct 14th 2018

    2. Saves and does the Jobs

      Using these belts on some Cedar. Been holding up if not doing better than the outrageous prices at Lowes, HD , etc. Empire is also very customer friendly and even over one or three belts. If they made a mistake they are about taking care of you! Even if it's on you they are awesome! on Aug 1st 2018

    3. Perfect fit in my DeWalt belt sander

      Doing some avocational production work making wood key tags from old growth pine, and the 220 and 400 grit belts save at least 50% of production time compared to the palm sanding jigs I used previously. Buy a few extra belts, the finer grits load up fairly quickly when working with resinous stock. I’ll definitely work with Empire Abrasives in the future. on Mar 24th 2018
