Dewalt DW3508 Cut-off Wheel 6.5 in 24 Grit Aluminum Oxide

Product Description

The DEWALT DW3508 is a Type 1 (01/41) flat cut-off wheel designed for cutting steel and ferrous metals. It measures 6.5 inches in diameter with a 0.125-inch thickness and a 5/8-inch DM arbor hole. The abrasive matrix is aluminum oxide, bonded with a resinoid bond and reinforced for added burst resistance under load. Rated at 9400 maximum RPM, the DW3508 is built for use with angle grinders and cut-off tools common in HVAC fabrication, plumbing rough-in, and general metalwork. At 24 grit, it removes material aggressively, making it appropriate for cutting stock rather than grinding or finishing.

This wheel is intended for cutting steel in trade and light industrial applications. It fits standard angle grinders and cut-off machines that accept a 5/8-inch DM arbor. Typical uses include cutting conduit, threaded rod, strut channel, sheet metal, and structural steel in the field or shop. The Type 1 flat profile is suited for straight plunge and chop cuts. The A24R specification designation confirms a 24-grit aluminum oxide wheel with R-hardness grade resinoid bond, which balances wheel life against cut rate on ferrous stock.

Key Features

• 6.5-inch diameter Type 1 flat profile for straight cuts on steel
• Aluminum oxide abrasive with resinoid bond and reinforced construction
• 24 grit for aggressive material removal on ferrous metals
• 9400 maximum RPM rating for use with compatible angle grinders and cut-off tools
• 5/8-inch DM arbor hole fits standard grinder spindles
• A24R specification designation for consistent hardness and bond grade

Compatibility

Designed for use on angle grinders and cut-off machines with a 5/8-inch DM arbor that operate at or below 9400 RPM. Rated application is steel cutting.

Installation Notes

Cut-off wheels must be installed and used by personnel familiar with abrasive wheel safety per ANSI B7.1 guidelines. Always verify the tool's rated RPM does not exceed the wheel's 9400 RPM maximum before mounting. Inspect the wheel for cracks or chips before each use and never operate a damaged wheel. Wear appropriate eye protection and a face shield when cutting, and ensure workpieces are secured before beginning a cut.
