Dewalt DW4428 Concrete Masonry Cutting Wheel 4x1/8x5/8 in

Product Description

The DEWALT DW4428 is a Type 1 abrasive cutting wheel engineered for cutting concrete and masonry materials. Measuring 4 inches in diameter with a 1/8-inch thickness and a 5/8-inch arbor bore, this wheel mounts to standard angle grinders and cut-off tools. It is designed for straight, controlled cuts through concrete block, brick, mortar, and similar masonry substrates. Weighing 0.25 pounds, it is a lightweight, single-use consumable intended for repeated field use by masonry contractors, tile setters, and general construction tradespeople who require a reliable abrasive wheel on the job site.

This cutting wheel is suited for residential and commercial masonry applications where an angle grinder or handheld cut-off tool is the primary cutting instrument. Typical use cases include scoring and cutting concrete block, cutting through cured mortar joints, trimming brick to fit, and making relief cuts in concrete slabs. The 4-inch diameter and slim 1/8-inch kerf width make it practical for detail cuts and confined-space work where larger blades cannot maneuver effectively.

Key Features

• 4-inch diameter fits standard small-angle grinders and cut-off tools
• 1/8-inch thickness delivers a narrow kerf for precise masonry cuts
• 5/8-inch arbor bore for secure, centered mounting on compatible spindles
• Rated for concrete and masonry cutting applications
• Lightweight at 0.25 pounds for reduced operator fatigue during extended use
• Sold individually — minimum order quantity of 25 units per order

Compatibility

Designed as an OEM-style consumable cutting wheel for use with angle grinders and cut-off tools accepting a 5/8-inch arbor and accommodating a 4-inch diameter Type 1 abrasive wheel.

Installation Notes

Mounting and replacement of abrasive cutting wheels should be performed by qualified personnel familiar with angle grinder safety. Always power down and disconnect the tool from its power source before changing wheels. Inspect the wheel for cracks or damage before each use and never operate above the maximum RPM rating printed on the wheel. Eye protection, hearing protection, and appropriate respiratory protection are required when cutting concrete or masonry per OSHA and ANSI B7.1 guidelines.
