Dewalt DW4309 Orbital Sanding Disc 5 Inches 80 Grit

Product Description

The DEWALT DW4309 is a 5-inch orbital sanding disc rated at 80 grit, designed for use with random-orbit sanders in professional finishing and material removal applications. The 80-grit abrasive level makes this disc suited for moderate stock removal, surface leveling, and prep work before moving to finer grits. At 0.01 pounds per disc, the DW4309 is a lightweight consumable that integrates easily into standard sanding workflows. Tradespeople and skilled contractors rely on this type of abrasive disc for consistent scratch patterns and controlled material removal across wood, drywall, and painted surfaces.

This disc is appropriate for residential and light commercial finishing work where a 5-inch random-orbit sander is the tool of choice. Common applications include wood floor preparation, cabinet sanding, drywall feathering, and surface prep before priming or coating. The 80-grit designation places it in the medium-abrasive category, making it a frequent first-pass disc in multi-stage sanding sequences. It is sold individually and is a standard consumable for finishing carpenters, painters, and general contractors.

Installation Notes

Mounting and disc changes should be performed with the sander unplugged or the battery pack removed. Ensure the sanding pad backing is clean and free of debris before attaching the disc to maintain proper adhesion. Inspect the disc for tears or uneven wear before each use and replace immediately if damage is present. Discs of this grit are a consumable item and should be rotated out as soon as cutting action degrades.
