Dewalt DARB1G0825 Fiber Resin Disc 4.5in 80 Grit 25PK

Product Description

The DEWALT DARB1G0825 is a coated abrasive fiber resin disc designed for aggressive material removal on metal and other hard surfaces. Measuring 4.5 inches in diameter and rated at 80 grit, this aluminum oxide disc delivers consistent cut rate and durability across a wide range of grinding and blending tasks. The resin-over-resin bond construction supports the abrasive grain under load, helping maintain disc integrity during sustained use. This disc is sold in a 25-pack, making it a practical choice for contractors, fabricators, and trade professionals who run angle grinders regularly on job sites or in the shop.

The DARB1G0825 is suited for use on mild steel, stainless steel, and other ferrous metals in both residential and commercial applications. Typical use cases include weld blending, rust removal, surface prep before coating or welding, and edge deburring. The 80-grit aluminum oxide formulation sits in a medium-aggressive range, making it appropriate for stock removal work where a finer finish is not the primary objective. Electricians, pipefitters, ironworkers, and HVAC sheet metal technicians commonly keep this grit range on hand for general metalwork and ductwork fabrication.

Key Features

• 4.5-inch diameter fits standard angle grinders commonly used in trade work
• 80-grit aluminum oxide abrasive for medium-aggressive material removal
• Resin-over-resin bond construction supports grain retention under load
• Fiber backing provides structural rigidity and resistance to disc flex during use
• 25-pack quantity reduces reorder frequency on active job sites

Compatibility

Designed for use with 4.5-inch angle grinders and disc grinders that accept fiber resin abrasive discs. Verify arbor size and grinder RPM rating against the disc specifications before installation.

Installation Notes

Installation should be performed by the operator before each use with the grinder unplugged or battery removed. Inspect each disc for cracks, tears, or damage before mounting — never use a damaged disc. Follow the grinder manufacturer guidelines and applicable ANSI B7.1 safety standards for abrasive wheel mounting and guarding. Always wear appropriate eye, face, and hand protection during grinding operations.
