Dewalt DARB1G0805 Fiber Disc 80 Grit 4-1/2 Inches 5 Pack

Product Description

The DEWALT DARB1G0805 is an aluminum oxide fiber disc designed for aggressive material removal on metal, weld seams, and surface preparation applications. Built on a resinoid-bonded fiber backing, this 80-grit medium-grade disc delivers consistent cut rate and durability across grinding and blending tasks. The disc measures 4-1/2 inches in diameter with a 7/8-inch arbor hole for standard angle grinder fitment. Rated to a maximum of 13,300 RPM, it handles sustained workloads without glazing. Each package contains five discs, making it a practical choice for contractors and fabricators who cycle through abrasives regularly.

This fiber disc is suited for use on ferrous metals, mild steel, and structural welds in both residential and light commercial fabrication environments. It is commonly used by ironworkers, welders, pipefitters, and general contractors for weld blending, rust removal, and surface conditioning prior to coating or painting. The medium 80-grit rating removes material efficiently without excessive surface scarring, bridging the gap between heavy stock removal and finish work.

Installation Notes

Fiber discs must be mounted on a matched backing pad rated for the grinder speed before use. Always confirm the grinder RPM does not exceed the 13,300 RPM disc rating before starting. Disconnect power or remove the battery from the grinder before changing discs. Inspect each disc for cracks, tears, or moisture damage before mounting, and never use a damaged disc.
