Product Specification


Benchmark Abrasives 2" x 42” Aluminum Oxide Sanding Belts are MADE IN USA. Each belt is made with a durable polycotton blend backing for durability and bi-directional tape joints that allow our belts to be run in either direction. We suggest only dry sanding applications with the A/O belts (Zirconia & Ceramic belts can be used wet/dry).

Our belts are made with the premium aluminum oxide grains and adhered to cloth backing that meets strict European standards, providing both long life and precision cuts.  These belts are designed for use on ferrous metals, composite materials, wood, plastics, and other metals. It features good abrasion resistance, anti-static and anti-clogging.

Aluminum Oxide (A/O) is the most commonly used grain at an economical price point.  If you are looking for more aggressive stock removal or a premium option, check out our Zirconia and Ceramic options.

Safety Tips & Techniques:

  • Start off using a lighter touch to dial in the belt on your material, especially when using the coarse belts.  The coarse grit can remove more material than you are looking to remove.
  • Always wear proper PPE to include (but not limited to) safety glasses, hearing protection, respirator, and hand protection.  Keep all guards in place on your machine.
  • Not every sanding belt machine will work with every size belt.  Make sure to read the machine operating manual to ensure you are purchasing the correct belt for your machine.
  • If you can’t find the size, grain or grit you are looking for, contact us for a personalized quotation.
