Will the cup diamond grinding disc remove epoxy paint from a concrete porch?
Asked by: Jimmy7777
Yes, but be aware that you might want a different grinding disc instead. The one in this kit includes a general purpose disc (DC510). You might want to get the DC500 instead which is specifically intended for paint removal. I think the only difference is how much abrasion is provided. The one in the kit will definitely work. The other would probably take off less of the surface.

9.5 Amp Corded 5 in. Surface Concrete Grinder Kit with Concrete Surfacing Attachment is rated 3.7 out of 5 by 11.

It was easy to put together, and initially the results were great. However, the grinding wheel did not last long. I was getting up thinset off our floor. It made it about 80 sq feet before it was worn out. Some areas the amount I was doing was thick, but it should have lasted much longer. The replacement wheels are $100 for this model. Very disappointed in this product by Bosch. Will definitely reconsider buying this brand in the future.

I bought this tool to grind down the heavy mortar mix that adhered the tile to the concrete slab. I used the supplied concrete surfacing attachment and it worked vey well, grinding down the mortar smoothly and without having to exert a lot of downward pressure. I also used the dust control attachment and attached it to a wet/dry vacuum. I put up plastic sheets on furniture, counters, walls, etc., to try and contain the dust. Although that helped keep the dust down, there was still an enormous amount of dust generated, which managed to get out and get all over everything... and I do mean everything! I don't blame the grinder, it's just the result of grinding in general. In the future, I may try something other than grinding. That said, I am very happy with my purchase of this grinder.

If you are buying this tool for concrete grinding, you really want to get the CSG15 instead, even though it is substantially more money. I bought this kit and used it as intended for its intended purpose of concrete grinding and burned the motor out in about 30 minutes. I suspect I probably just got a bad unit though. I didn't use it for any other purpose but it felt like it would make a good general purpose grinder. I ended up buying the CSG15 and it was sooooo much faster and felt like it had all kinds of power compared to this tool. I was able to cover about 3x the surface area in the same amount of time with the CSG15 than I did with this kit, which is based on the 1821 rat tail model. The CSG15 also has some automatic shutoff built-in to prevent overheating that this model didn't have and the CSG15 was generally easier to control. Both kits use the same 5" Bosch diamond grinding wheel.

The motor burnt up with only a couple weeks of use, since it was an online purchase the store could not refund the $25.00 EPP. They did refund the price of the drill. This tool should not be used for use on concrete even though it is advertised that way.

Rated 5 out of 5 by from Grinder Grinding Awesome! I used to grind floors in the Palm Springs area for residents, so I have had previous experience. This little guy does a great job! The deal for all the components is unmatched! Highly recommend this equipment. Thank you very much.
