The DEWALT DW4772T XP Turbo Diamond Cup Wheel is a 4-inch professional-grade wheel built for aggressive dry grinding and finish work on concrete and masonry. It features high diamond concentration, large grinding segments, and a heat-treated steel body for long life. The double rim design adds durability and speeds up material removal, making it a reliable choice for smoothing uneven surfaces, leveling, and shaping masonry. With a 5/8-11 arbor and a maximum speed of 15,000 RPM, this wheel fits most angle grinders and delivers consistent performance on demanding jobs.
The 4-inch size is ideal for working in tighter areas, around corners, and on smaller projects where a 5-inch wheel is too bulky. It remains powerful enough for grinding concrete blocks, patching mortar, and removing thin-set. The compact footprint gives you control and visibility for detailed work.
Use the DW4772T to dry grind concrete, masonry, and stone. Smooth out uneven surfaces, remove form lines, and shape edges. The double rim design ensures consistent wear and a longer usable life, even under tough conditions.

The DW4772T's 4-inch diameter strikes a balance between control and coverage. It is easier to handle in tight spots and works well for detail grinding. If you need wider passes on a large slab, step up to a 5-inch version like the DW4777T. Both wheels share the same XP Turbo construction, so you get consistent performance across sizes.
To get the most from your DW4772T, avoid putting excessive pressure on the grinder. Let the diamond segments do the work, and move in a steady, sweeping motion. This reduces heat buildup and prevents glazing, keeping the wheel sharp for more jobs.
No, this wheel is designed for dry grinding only. Using it wet may damage the segments or the steel body.
The double rim increases the surface area of the rim, which extends the lifespan of the wheel and allows for faster material removal compared to a single rim.
Yes, the wheel has a 4-inch diameter and a 5/8-11 arbor, which fits most 4-1/2 inch angle grinders. Always check your grinder's arbor size and maximum RPM before use.
This diamond cup wheel is intended for concrete and masonry. For metal grinding, use a dedicated metal grinding wheel.
Works fast, no fuss.
I used this on a small concrete repair. It removed material quickly and the dust didn't clog. Good wheel.
I grind a lot of concrete for my foundation work. This double-rim wheel lasts longer than the single-rim ones. It does generate a lot of dust, so wear a mask. The 5/8 arbor fit my grinder perfectly. I like that it doesn't wobble at high speed. It's a bit pricey but worth it for the life.
I use it to sharpen edging on stone steps. It's aggressive but manageable.
Perfect for smoothing concrete patches. Highly recommended.
