Sanding Belts

Infinity Tools stocks the Mirka Abranet Max sanding belts and a palm sander replacement belt set (80/100/120 grit 3-piece). Both are available in the sanding belts collection.

Mirka Abranet Max belts use a synthetic mesh backing with an open-lattice abrasive surface that self-cleans as you sand, preventing dust from loading and clogging the belt. This results in a longer cutting life, less heat buildup, and a more consistent scratch pattern compared to conventional paper-backed belts.

Start with 80 grit for heavy material removal or leveling rough surfaces, then step up to 100 or 120 grit for intermediate smoothing. Finish with 150 grit or finer before staining or applying a clear coat. Skipping grit steps leaves visible scratch marks that show through finish.

Belt sander belts are sized by width and length (for example, 3x21 inches or 4x24 inches). Check your sander's manual or the belt currently installed on your machine for the correct dimensions before ordering. Using a belt that is too wide or too narrow will prevent proper tracking.

Use a rubber cleaning stick periodically during sanding to clear loaded resin and wood dust from the belt face. Avoid excessive pressure, which causes heat buildup and glazing, and let the abrasive do the cutting at its own pace. Browse sanding accessories for cleaning tools.

Yes. Sanding belts are effective on hardwoods, though denser species load the abrasive faster than soft or medium-density woods. Using a Mirka Abranet Max belt with dust extraction helps control loading when working with dense hardwoods.

Sanding belts are designed for handheld belt sanders and stationary belt/edge sanders. They should not be used on spindle sanders or disc sanders, which require sleeves and discs respectively. For those applications, see our sanding drums & sleeves collection.

Palm sander replacement belt sets are pre-cut belts sized to fit compact palm-style belt sanders. The 3-piece 80/100/120 grit set available at Infinity Tools provides a progression of grits in one purchase, ideal for keeping your palm sander stocked for project-to-project use.

Always sand parallel to the wood grain with a belt sander whenever possible. Cross-grain passes leave scratch marks that are difficult to remove and highly visible under stain or clear finish. On end grain, diagonal passes are sometimes necessary, followed by a final with-the-grain pass.

After belt sanding, follow up with hand sanding or a random orbit sander at a finer grit to remove any linear scratches left by the belt. Remove all dust with a vacuum and tack cloth before applying any stain or topcoat. Explore our stains, paints & finishes collection for compatible finishing products.
