3 Pieces Diamond Cup Grinder 4 Inch Concrete Turbo Diamond Grinding Cup Wheel 12 Segs Heavy Duty Angle Grinder Wheels for Angle Grinder

Worked well, seems durable, nothing more to say but I liked it enough to leave a review.

I purchased this to grind down some uneven spots in a concrete sidewalk. Was blown away with the quality of this item. Finished the entire job and barely made a dent on the first grinder. Highly recommend. Excellent product for the price.

These diamond cup wheels get the job done. I used them on concrete with a standard angle grinder, and they removed material quickly without bogging down. The 12-segment design gives good grinding power, especially for leveling and smoothing rough spots. You do get a decent amount of dust (as expected), so definitely use proper protection. They’re not top-tier professional grade, but for the price—especially getting a 3-pack—they’re a great value for DIY or occasional use. They seem to hold up well so far, but I’d say they’re best suited for lighter to moderate jobs rather than all-day heavy commercial use. Pros: • Good material removal • Fits standard angle grinders • Great value for a 3-pack Cons: • Dusty (normal for concrete work) • Not premium-grade for heavy daily use Overall, solid performance for the money.

These are working quite well. I'm installing large patio blocks and using these to clean up edges and make both inside and outside curved cuts and these have performed great.

Used to grind down concrete for an epoxy coating. These diamobd cup grinding wheels held up great and only had to use one wheel on a 700 square foot area. Would buy again.

Redoing the tile floor in our bathroom. Tile came up good but left all mortar attached to the concrete floor. Needed something to remove the mortar. These disc work great. Came in a timely manner. Used 1 disc to get floor perfectly flat and clear of old mortar. Will definitely use again. One caution: there will be an extreme amount of fine dust from the mortar.

Grinder wheels worked great- and last a long time- have been using them to grind down concrete bumps and cracks.

For the price, it is definitely worth it!

Buena calidad, durable, lo recomiendo

Se ve bien el producto El no venir empaquetado adecuadamente con el sello del fabricante me causa un poco de desconfianza
