Dewalt DW8720 Type 1 Cut-off Wheel 4 in 60 Grit

Product Description

The DEWALT DW8720 is a Type 1 (01/41) reinforced aluminum oxide cut-off wheel designed for aggressive cutting on steel and stainless steel. At 4 inches in diameter and 0.035 inches thick, it mounts on right-angle grinders and cut-off tools with a 3/8-inch arbor hole. The resinoid bond and 60-grit aluminum oxide abrasive deliver consistent cutting action across a range of ferrous and stainless applications. Rated to 19000 RPM, this wheel is built for fast, controlled cuts in fabrication, maintenance, and field service work. It is installed and used by millwrights, pipefitters, welders, and general metalworkers.

This cut-off wheel is suited for both shop and field use where precise, clean cuts on steel and stainless steel are required. Typical applications include cutting structural steel, pipe, rod, and sheet metal. Its compact 4-inch diameter makes it well matched to smaller angle grinders and pneumatic cut-off tools commonly used in tight spaces or overhead work. The A60T specification indicates a standard aluminum oxide grain, 60 grit, and T hardness grade — a general-purpose combination appropriate for production and repair cutting alike.

Key Features

• Type 1 (01/41) flat wheel profile for straight, plunge, and slot cutting
• 60-grit aluminum oxide abrasive with resinoid bond for consistent cut performance
• Reinforced construction to resist breakage under lateral load
• 19000 RPM maximum speed rating
• 3/8-inch arbor hole fits standard small-grinder spindles
• Rated for steel and stainless steel cutting

Compatibility

Designed for use on right-angle grinders and cut-off tools accepting a 4-inch diameter, 3/8-inch arbor wheel running at or below 19000 RPM. Suitable for cutting steel and stainless steel workpieces.

Installation Notes

Installation should be performed by a qualified operator following ANSI B7.1 safe-use guidelines for abrasive wheels. Inspect the wheel for cracks or chips before mounting and never exceed the marked maximum RPM. Ensure the grinder guard is in place before operation, and allow the wheel to run up to speed before contacting the workpiece. Do not apply side pressure to a Type 1 cut-off wheel.
