Dewalt Accessories DWA4511H Metal Grinding Wheel 25 Pack

Product Description

The DEWALT ACCESSORIES DWA4511H is a high-performance metal grinding wheel designed for aggressive stock removal on hard metal surfaces. Measuring 4.5 inches in diameter and 1/8 inch thick with a 5/8-11 arbor bore, this wheel fits standard angle grinders used across fabrication, maintenance, and industrial applications. The abrasive grain is high-concentration aluminum oxide, formulated for a softer bond that keeps the wheel cutting freely without glazing. Three full sheets of fiberglass reinforcement provide structural integrity under load. This package contains 25 wheels, making it a practical supply for busy shops or service contractors.

This wheel is suited for cutting and grinding ferrous metals including mild steel, structural steel, and iron. It is commonly used in metal fabrication shops, welding operations, pipefitting, and general industrial maintenance. The 5/8-11 arbor size is the standard thread found on most 4.5-inch angle grinders, making these wheels a drop-in fit for the tools already on the job. The 1/8-inch profile handles grinding and light notching tasks where a thin kerf is not required.

Installation Notes

Abrasive wheels must be installed by a qualified operator following ANSI B7.1 and applicable OSHA standards for abrasive wheel machinery. Inspect each wheel for cracks or damage before mounting and never use a damaged wheel. Confirm the grinder RPM rating meets or exceeds the wheel maximum RPM before operation, and ensure the guard is properly in place. Wear appropriate PPE including eye protection and a face shield during use.
