Dewalt DW4429 Concrete Masonry Grinding Wheel

Product Description

The DEWALT DW4429 is a depressed-center grinding wheel designed for cutting and grinding concrete and masonry surfaces. Measuring 4 inches in diameter with a 1/4 inch thickness and a 5/8 inch arbor bore, it mounts directly to small angle grinders commonly used in the field. The wheel is built for aggressive material removal on hard mineral substrates including poured concrete, block, brick, and mortar. Masonry contractors, tile setters, and concrete finishers reach for this wheel when they need consistent stock removal without changing tools. At 0.3 pounds, it adds minimal weight to the grinder during extended use.

The DW4429 is suited for residential and light commercial masonry work where a compact 4 inch grinder is the tool of choice. Typical applications include grinding down high spots on slabs, cleaning up mortar joints, beveling concrete edges, and surface prep before patching or coating. It is sold individually and is well-matched to corded and cordless small-diameter angle grinders with a standard 5/8 inch arbor.

Installation Notes

Grinding wheels of this type are installed and serviced by masonry contractors, tile installers, and concrete finishers. Before mounting, confirm the grinder is unplugged or the battery is removed and the spindle is fully stopped. Inspect the wheel for cracks or chips before each use and never operate a damaged wheel.
