About Product Overview

This 4.5" diamond cup wheel from DEWALT's Extended Performance line is built for grinding down concrete, mortar, and masonry with an angle grinder. The diamond segments hold up under heavy material removal, so you're not swapping wheels every few minutes on a job that requires real grinding, not just surface cleanup.

With a 5/8" arbor, it fits standard angle grinders, and the max speed rating of 13,300 RPM means it's matched to run safely on the tools most contractors already own. The 1.5" thickness gives the segments enough body to grind flat and stay flat, which matters when you're leveling a slab or knocking down high spots in a poured floor.

It ships one per package in clamshell packaging, so it's easy to grab off the shelf and go. Good fit for concrete finishers, masons, and remodelers doing surface prep, coating removal, or leveling work where a standard grinding wheel would wear out too fast.

  • Diameter: 4-1/2 inches
  • Thickness: 1.5 inches
  • Arbor size: 5/8 inch
  • Material: Diamond
  • Max speed: 13,300 RPM
  • Compatible with angle grinders

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
