High-Performance 4-Inch Turbo Diamond Grinding Cup Wheel for Concrete, Stone, and Ceramic Surfaces - Heavy-Duty Angle Grinder Accessory (Yellow) Review

I needed to remove some concrete for my driveway and it worked beautifully. I use a Makita 4" angle grinder and have had no problems. The product comes with a shim to adjust for a smaller mandrel.

This cup wheel is worth the money. I've used it on stone, brick and concrete and it has never let me down. Works just as well as mugs 3 times more expensive. This size is easy to control with one hand and is great for single parts and small areas.

Suitable for Makita N9514B. I had to remove the hubcap, after that it works fine, I found it works better with wet concrete. It will take time, grind slowly and it should never be necessary to force the tool. Inexpensive sidewalk renovation.

this is not bolted on (no nut welded on) so you will need to secure it with a saw blade nut. Otherwise it is in no way inferior to the Dewalt product. I gave five stars because it's a good buy in terms of value for money.

Used for sanding raised sidewalk edges. It works great with my cheap HFT angle grinder. I'm actually pleasantly surprised. Yes, it takes time and is dusty even when water is added, but it probably saves hundreds of dollars over discontinuation.

Great Product I have a 10 x 10 foot plate that needs sanding. In fact, the blades are worn down to 1/16 inch. Ordered three more to finish. Use wet or dry, I started dry, there was so much dust in the air it looked like a foggy morning. Moisten concrete, leave for 15 minutes. No dust when wet.

Bought two hoping they will wear out over time. These things are useless, it took so much effort to grind a small amount of concrete. Returned both and bought one from their own stock which was significantly more expensive but what a night and day difference. You really do get what you pay for with this product. I would avoid it if I were you.

Does the job. I ordered these to use with my Makita angle grinder to fix a bad concrete pour after we replaced our drainage tiles. I went through 3 blades and emptied the store vacuum 3 times. My first order only received 1 knife. I ordered another time, two blades came. That 4th blade may have done the job.
