Tru-maxx 7307 Abrasive Belt 100 Grit 4x132 in Aluminum Oxide

Product Description

The TRU-MAXX 7307 is a coated abrasive belt designed for high-volume material removal and finishing on stationary and portable belt sanders. It measures 4 inches wide by 132 inches long and runs at 100 grit, placing it in the fine grade range — suited for final stock removal, surface prep, and light finishing passes on metal, wood, and composites. The belt uses an aluminum oxide abrasive grain bonded to a heavyweight polyester cloth backing rated at X-weight, which provides flexibility and tear resistance under sustained dry operation. Closed coat density keeps grain coverage high for consistent scratch patterns across the full belt surface.

This belt fits wide-format belt grinders, floor-standing belt sanders, and industrial finishing machines that accept 4 inch by 132 inch belts. The 100 grit fine grade makes it appropriate for prep work ahead of painting or coating, weld seam blending, and deburring light stock on ferrous and non-ferrous metals. It is also used in woodworking shops for final dimensioning and surface smoothing on hardwoods. Dry operation only — this belt is not rated for wet grinding applications. Typical users include metal fabricators, machinists, welders, and production woodworkers.

Key Features

• 100 grit fine grade — effective for surface prep, blending, and light finishing
• Aluminum oxide abrasive grain provides consistent cut rate on metal and wood
• X-weight polyester cloth backing resists tearing and flexing fatigue during extended runs
• Closed coat density delivers uniform scratch pattern and high material contact
• Dry operation design — no coolant or water exposure required
• 4 inch by 132 inch format fits a wide range of stationary industrial belt sanders

Compatibility

Designed for use on stationary and portable belt sanders and grinders that accept a 4 inch by 132 inch abrasive belt. Verify platen and tracking system dimensions before installation.

Installation Notes

Belt sander installation should be performed by qualified shop personnel with the machine unplugged or locked out per OSHA lockout/tagout procedures. Confirm belt tracking direction matches the arrow printed on the belt backing before tensioning. Inspect the platen and contact wheel for wear or damage before mounting a new belt. Do not run this belt in wet or coolant-flooded conditions — it is rated for dry use only.
