Dewalt DW8427 Thin Cutting Wheel 7x0.045x7/8 in

Product Description

The DEWALT DW8427 is a bonded abrasive thin cutting wheel engineered for fast, clean cuts through metal and ferrous materials. Measuring 7 inches in diameter, 0.045 inches thick, and with a 7/8-inch arbor bore, this wheel mounts on standard 7-inch angle grinders used by electricians, plumbers, pipefitters, and general trade contractors. The thin kerf profile reduces material loss and heat buildup during cutting, making it well-suited for sheet metal, conduit, pipe, and strut work on the job site.

This cutting wheel is intended for use with 7-inch angle grinders in residential and commercial trade applications. It is a single-use consumable that is replaced as part of routine tool maintenance. Common install scenarios include cutting EMT conduit, copper and steel pipe sections, threaded rod, unistrut, and light structural steel. The 7/8-inch arbor fits the most common grinder spindle configurations used across trades.

Key Features

• 7/8-inch arbor bore accommodates the most common grinder spindle size
• Bonded abrasive construction suited for metal and ferrous material cutting

Compatibility

Designed for use with 7-inch angle grinders accepting a 7/8-inch arbor. Confirm maximum RPM rating of the grinder meets or exceeds the wheel rating before mounting.

Installation Notes

Cutting wheels must be installed and operated by qualified tradespeople following tool manufacturer guidelines and applicable ANSI B7.1 safety standards for abrasive wheel use. Always power down and disconnect the grinder before changing wheels. Inspect the wheel for cracks or damage before each use and never exceed the rated maximum RPM. Eye protection, gloves, and appropriate PPE are required when operating angle grinders with abrasive cutting wheels.
