Tru-maxx 7109 Abrasive Belt 320 Grit 1x30 in Aluminum Oxide

Product Description

The TRU-MAXX 7109 is a coated abrasive belt designed for dry precision finishing on portable and stationary belt sanders. It measures 1 inch wide by 30 inches long and cuts with 320-grit aluminum oxide, placing it in the extra fine grade range. The closed-coat construction keeps abrasive mineral density high across the full belt face, which supports consistent scratch patterns on metal, wood, and composite surfaces. The polyester cloth backing is rated X-weight, giving it the stiffness and tear resistance needed for production runs and repetitive finishing passes. This belt is a standard choice for machinists, fabricators, and finishing tradespeople working with bench-top or handheld belt sanding equipment.

This belt is suited to light stock removal, surface prep, and fine finishing in dry operating conditions. Common applications include deburring metal workpieces, blending weld seams, smoothing hardwood, and preparing surfaces before coating or inspection. The 1 inch by 30 inch format fits a wide range of narrow-platen and file-type belt sanders used in metalworking shops, maintenance facilities, and light fabrication environments. It is sold individually, with a minimum order quantity of 10 units per purchase.

Installation Notes

Belt installation should be performed with the sander unplugged or power source locked out. Verify belt tracking adjustment after seating to prevent edge contact with the platen or guards. Inspect the belt for tears or glazing before each use and replace when cutting action degrades. Always confirm the arrow or directional marking on the belt aligns with sander drive direction before powering on.
