Dewalt DW8080 Type 1 Cut-off Wheel 4.5 in Aluminum Oxide

Product Description

The DEWALT DW8080 is a Type 1 (01/41) reinforced aluminum oxide cut-off wheel designed for aggressive cutting on ferrous and non-ferrous metal surfaces. At 4.5 inches in diameter with a 3/32-inch thickness and a 7/8-inch arbor hole, this wheel fits standard 4.5-inch angle grinders and die grinders used in fabrication, welding prep, and field cutting applications. The 30-grit aluminum oxide abrasive paired with a resinoid bond and S hardness code delivers clean, fast cuts. Rated at 13,300 maximum RPM, the wheel handles demanding cutting tasks while the reinforced fiberglass construction resists breakage under lateral stress.

The DW8080 is suited for cutting steel and stainless steel in residential and commercial applications, including structural steel fabrication, pipe cutting, sheet metal work, and general maintenance. It is a single-wheel unit commonly used by ironworkers, pipefitters, welders, and general contractors who rely on 4.5-inch angle grinders as a standard shop and field tool. The 3/32-inch thin kerf minimizes material loss and heat buildup during the cut.

Key Features

• Reinforced aluminum oxide abrasive with 30-grit rating for fast metal cutting
• Type 1 flat profile designed for straight-line cutoff work
• Thin 3/32-inch kerf reduces heat buildup and material loss
• 13,300 maximum RPM rating compatible with standard 4.5-inch angle grinders
• Resinoid bond with S hardness code for consistent cut performance on steel and stainless steel
• 7/8-inch arbor hole fits common grinder spindle sizes

Compatibility

Designed for use on steel and stainless steel with standard 4.5-inch angle grinders or die grinders accepting a 7/8-inch arbor and rated at or above 13,300 RPM.

Installation Notes

Mount this wheel on a grinder whose nameplate RPM meets or exceeds 13,300 RPM before use. Always verify the arbor hole fits the spindle securely and that the guard is in place before starting the tool. Do not use this Type 1 flat wheel for grinding or side-loading; it is rated for straight cutoff cuts only. Inspect the wheel for cracks or chips before each use and discard any damaged wheel immediately per ANSI B7.1 safety standards.
