The DeWALT DW4961 4 in x 2 in Type 11 Masonry Grinding Wheel is a steel-backed cup wheel made for grinding concrete and masonry surfaces. This is a masonry grinding wheel designed for aggressive surface grinding and material removal. Model Number: DW4961. If you need to knock down high spots, clean up rough edges, or prep hard surfaces before the next step, this wheel is built for that kind of work.

What matters here is the wheel recipe and the shape. DeWALT uses an aluminum oxide and silicon carbide abrasive mix for long life and strong material removal, and the Type 11 cup profile gives you more usable contact area on the work. In plain terms, it helps the grinder stay productive on concrete, block, and masonry instead of glazing over too quickly. The extra coarse grit and tough-surface design make it better suited to stock removal and surface prep than finish work.

The build is set up for jobsite abuse. A metal backing adds durability, and the wheel uses fiberglass reinforcement for strength and safety. DeWALT also calls out a proprietary material mix for aggressive grinding action, which fits what you want from a cup wheel in this class: solid bite, decent life, and consistent performance on abrasive material. With a 4-inch diameter, 2-inch wheel height, and 5/8 in-11 threaded arbor, it is sized for common grinder setups used for masonry grinding.

From a practical standpoint, this is the kind of wheel that makes sense when you are working on concrete patch prep, leveling uneven spots, dressing masonry edges, or cleaning up surfaces before coating or repair. The 9,000 RPM max rating gives you a clear operating limit, and the threaded center makes installation straightforward on compatible grinders. It is not a fine finishing accessory. It is for getting after hard material efficiently.

The compatibility side is simple and useful. Source data lists angle grinders, bench grinders, and die grinders as compatible devices, and the wheel uses a 5/8 in-11 center hole thread. That thread size is one of the key buying specs because it tells you whether the wheel will fit your grinder without adapters. For most buyers, the real check is matching the 5/8 in-11 interface and making sure your tool is intended for this style of cup wheel.

Who should buy it? Masonry contractors, remodelers, concrete crews, and serious DIY users who need a dedicated grinding wheel for hard mineral-based material. If your work involves concrete surface prep, masonry edge cleanup, or general grinding where removal rate matters more than finish quality, this wheel is a sensible pick. If you need a smoother final surface, you would typically step to a different wheel after the heavy grinding is done.
