Dewalt DARB1G0305 Fiber Resin Disc 4.5in 36G 5PK

Product Description

The DEWALT DARB1G0305 is a coated abrasive fiber resin disc designed for heavy material removal on metal, weld seams, and other hard surfaces. Built on a fiber backing and bonded with a resin system, these discs use aluminum oxide (AO) grain at 36 grit for aggressive stock removal. At 4.5 inches in diameter, they fit standard right-angle grinders commonly used by HVAC fabricators, pipefitters, plumbers, and sheet metal workers. Each pack contains five discs, making them practical for jobsite use where discs cycle through quickly under heavy grinding loads.

These discs are suited for grinding and deburring ferrous metals, structural steel, pipe ends, and weld beads in both residential and commercial mechanical applications. The 36-grit cut is coarse enough to handle scale, rust, and excess weld material before transitioning to finer finishing steps. Tradespeople who work with angle grinders on pipe prep, flange face cleanup, and rough surface conditioning will find these discs useful across a range of daily tasks.

Key Features

• Aluminum oxide grain for consistent, aggressive cutting action on ferrous metals
• 36 grit for fast stock removal and weld bead grinding
• 4.5-inch diameter fits standard right-angle grinders
• Fiber backing with resin bond for durability under load
• Sold in a 5-pack for extended jobsite use

Compatibility

Designed for use with standard 4.5-inch right-angle grinders equipped with an appropriate fiber disc backing pad and center nut assembly.

Installation Notes

These discs are installed and serviced by tradespeople using right-angle grinders. Always ensure the grinder is disconnected from power and the disc is fully seated on a compatible backing pad before securing the center nut. Inspect each disc for cracks or damage before use and never exceed the maximum RPM rating marked on the disc. Wear appropriate PPE including eye protection and gloves when grinding.
