Dewalt DARB1G0325 Fiber Resin Disc 4.5in 36G 25PK

Product Description

The DEWALT DARB1G0325 is a coated abrasive fiber resin disc designed for aggressive material removal on metal, weld seams, and rough surfaces. Built with aluminum oxide (AO) grain on a rigid fiber backing, the disc delivers consistent cut rates and resists loading under sustained pressure. At 4.5 inches in diameter and 36 grit, it is suited for heavy stock removal, deburring, and surface prep ahead of welding or coating. These discs are sold in a 25-pack, making them a practical choice for shop use or job-site supply. Trade professionals in metal fabrication, HVAC, and mechanical contracting reach for this grit level when scale, rust, or weld spatter needs fast takedown.

The DARB1G0325 fits standard 4.5-inch angle grinders found across commercial and industrial job sites. The 36-grit cut is appropriate for ferrous metals including mild steel and cast iron during initial surface preparation. It is also used on structural steel, pipe ends, and sheet metal in HVAC and plumbing fabrication shops. The 25-pack quantity supports continuous workflow without frequent resupply, making it suitable for service vans, tool cribs, and contractor supply staging.

Key Features

• Aluminum oxide grain for aggressive, fast-cutting performance on metal surfaces
• 36 grit rating targets heavy stock removal, rust scale, and weld spatter
• 4.5-inch diameter fits standard angle grinders
• Fiber resin backing resists flex and breakdown under load
• 25-pack quantity reduces per-disc cost and resupply frequency

Compatibility

Designed for use with standard 4.5-inch angle grinders commonly used in metal fabrication, HVAC, and mechanical trade applications.

Installation Notes

Fiber resin discs are installed and replaced by the operator before use — ensure the grinder is fully powered off and unplugged before mounting or removing a disc. Inspect the disc for cracks or damage before each use and never exceed the maximum RPM rating marked on the disc or grinder guard. Wear appropriate PPE including eye protection and gloves when operating angle grinders with abrasive discs. Follow applicable ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
