Dewalt DW8424H Hp Cutoff Wheel 4-1/2 X 0.045 X 5/8-11

Product Description

The DEWALT DW8424H is a bonded abrasive HP cutoff wheel designed for aggressive cutting of metal and other hard materials using angle grinders. Measuring 4-1/2 inches in diameter with a 0.045-inch thickness and a 5/8 inches-11 arbor mount, this thin-kerf wheel delivers fast, clean cuts with minimal material loss. The HP designation indicates a reinforced, high-performance construction suited to sustained professional use. Electricians, pipefitters, ironworkers, and general tradespeople rely on cutoff wheels like the DW8424H for cutting conduit, rebar, bolts, and structural stock on the jobsite.

This cutoff wheel is suited for use on 4-1/2-inch angle grinders equipped with a 5/8 inches-11 threaded spindle, which is the standard arbor size across most corded and cordless grinders in that disc-size class. Typical applications include cutting metal pipe, sheet metal, angle iron, and threaded rod in both residential and commercial construction, mechanical contracting, and industrial maintenance environments. The thin 0.045-inch profile reduces cutting resistance and heat buildup during repeated cuts.

Installation Notes

Cutoff wheels are installed and replaced by the operator before each use — no licensed trade certification is required, but proper PPE including a face shield and gloves is mandatory. Always power down and unplug or lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before each use and never exceed the maximum RPM rating marked on the wheel. Follow ANSI B7.1 safe-use guidelines for bonded abrasive wheels.
