Dewalt DWA8951H 4.5 in Ceramic Cut-off Wheel Type 1

Product Description

The DEWALT DWA8951H is a Type 1 (01/41) ceramic reinforced cut-off wheel designed for aggressive cutting on steel and stainless steel. Measuring 4.5 inches in diameter with a 0.045-inch thickness and a 5/8-inch arbor hole, it fits standard 4.5-inch angle grinders. The resinoid bond holds the ceramic abrasive grain firmly during high-speed operation, with a rated maximum of 13,300 RPM. At under 0.2 pounds, this thin wheel removes material quickly with minimal drag, making it a practical choice for metal fabrication, pipefitting, and mechanical work where clean, fast cuts matter.

This wheel is suited for cutting ferrous and non-ferrous metals in residential and commercial settings. Typical applications include cutting structural steel, pipe, rebar, sheet metal, and stainless steel components. The Type 1 flat profile is the standard configuration for right-angle grinders used by pipefitters, ironworkers, HVAC technicians, and general mechanical contractors. Its ceramic abrasive construction handles both mild steel and harder stainless steel grades without glazing over.

Key Features

• Ceramic abrasive grain cuts steel and stainless steel efficiently without glazing
• 0.045-inch thin kerf reduces heat buildup and material loss per cut
• Resinoid bond provides consistent grain exposure throughout wheel life
• 13,300 maximum RPM rating compatible with standard 4.5-inch angle grinders
• Type 1 flat profile fits most right-angle grinder guards without modification
• Reinforced construction resists shattering under cutting load

Compatibility

Designed for use with 4.5-inch angle grinders accepting a 5/8-inch arbor. Rated for cutting steel and stainless steel applications.

Installation Notes

Installation and operation should be performed by a qualified tradesperson familiar with angle grinder safety. Always power down and disconnect the grinder before mounting or removing a wheel, and confirm the grinder RPM rating meets or exceeds the wheel maximum before use. Inspect the wheel for cracks or chips prior to each use and never operate a damaged wheel. Ensure the guard is properly seated and all arbor hardware is tightened to grinder manufacturer specifications before starting the tool.
