Dewalt DW4546 Type 27 Grinding Wheel 6in 1/4in 24 Grit

Product Description

The DEWALT DW4546 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal surfaces. Built with a 24-grit aluminum oxide abrasive and a resinoid bond, it delivers fast stock removal on steel, iron, and weld seams. The wheel measures 6 inches in diameter and 1/4 inch thick, with a 5/8-11 threaded arbor hole for secure mounting on compatible angle grinders. A reinforced construction keeps the wheel stable at speeds up to 10,100 RPM. This wheel is a standard tool for fabricators, ironworkers, pipefitters, and maintenance mechanics working on structural steel and heavy weld cleanup.

The DW4546 is suited for surface grinding, weld blending, and edge cleanup on ferrous metals in both shop and field environments. The Type 27 depressed center profile allows the wheel face to make flat contact with the workpiece, improving control during flat surface grinding and heavy stock removal passes. It is commonly used in industrial fabrication, construction, and mechanical maintenance applications where a coarse cut rate is needed. The 5/8-11 threaded hub mounts directly to most standard angle grinders without an additional flange nut.

Key Features

• 24-grit aluminum oxide abrasive for aggressive stock removal on steel and ferrous metals
• Type 27 depressed center geometry provides flat-face contact for surface grinding
• Resinoid bond supports high-load grinding and resists heat buildup during sustained use
• Reinforced wheel construction rated to 10,100 RPM maximum operating speed
• 5/8-11 threaded arbor hole mounts directly to standard angle grinders without a separate flange nut
• Black and yellow color coding for quick identification on the jobsite

Compatibility

Designed for use with angle grinders accepting a 5/8-11 threaded arbor. Fits standard 6-inch Type 27 wheel guards. Suitable for grinding ferrous metals including mild steel, cast iron, and weld deposits.

Installation Notes

Installation and wheel changes should be performed by a qualified operator following ANSI B7.1 safety standards for abrasive wheel use. Always inspect the wheel for cracks or damage before mounting and never exceed the 10,100 RPM maximum rated speed. Power down and disconnect the grinder from its power source before mounting or removing the wheel. Wear appropriate PPE including a face shield, gloves, and hearing protection during operation.
