Choose your 3 × 21 sanding belts

Start with Cloth A/O for woodworking and compare Zirconia or Ceramic for metal removal. Cloth A/O also offers the finer grit choices on this product. Match the belt to your machine and work material.

Check fit before ordering

These belts are 3 inches wide with a 21-inch total loop length, for sanders that specify 3 × 21 belts. A 3 × 18 or 3 × 24 belt is a different size.

These are belt-size references. A matching size does not approve every abrasive or work material. Follow the exact model manual; some woodworking sanders prohibit metal or wet sanding.

Match both numbers in your machine manual. Follow the machine manufacturer’s instructions for installation, tracking, operating speed and dust collection.

What is in a pack?

Each pack contains 12 belts in one selected material and grit. It is not a mixed-grit assortment. Select separate packs when you need more than one grit.

Plan the next sanding step

Use the coarsest grit needed for the task, then refine its scratch with progressively finer grits. Test the sequence on scrap. Follow the coating or finish manufacturer’s instructions for the final grit.

Before you order

Will this belt fit my sander?

These belts are 3 inches wide with a 21-inch total loop length, for sanders that specify 3 × 21 belts. A 3 × 18 or 3 × 24 belt is a different size.

How many belts come in a pack?

Each pack contains 12 belts in one selected material and grit. It is not a mixed-grit assortment. Select separate packs when you need more than one grit.

Does every material come in every grit?

No. Each material has its own grit options. Compare the material-and-grit table, then use the selector for current availability and price.

Which 3 × 21 sanding belts should I choose for wood?

Start with Cloth A/O, the aluminum oxide option on this product. Select a grit for the amount of removal and the next finish. Zirconia and Ceramic are also offered for suitable metalworking applications; options vary by grit.

Can I use these belts for wet sanding?

Confirm wet-use suitability with Maverick for the exact belt specification and check the machine manual. Do not assume these belts or an electric belt sander are approved for wet use.

What if I need a different belt size?

Choose a product that matches both your required width and full loop length. Browse all sanding belt sizes or request a custom size; confirm the specification and current terms with Maverick.
