I've also used this grinder for an initial treatment on rough barn wood, and it's worked well. Sanding after takes much less time. It's a simple tool that does the job and lasts longer than a grit grinder wheel. So I like it a lot.
We ultimately needed to get one of these, to remedy an issue from our local city office. They mailed out FIX IT Notices for "Uneven sidewalk" segments.
We first tried using those $2 to $4 so-called Masonry/cement grinding wheels. What a waste of money!
Those are the cheap wheels hanging right above the side grinders at homedepot or lowes.
Had I known just How Much better a cupping wheel like this works, I would have bought it initially.
Almost a night and day difference between how this diamond cupping wheel works Vs. an el-cheapo $2 or $3 masonry wheel works.
The concrete and its dust really were something to behold when this wheel went to work on those "uneven edges".
Clouds of dust were produced without hardly any pressure being applied. I just let the cupping wheel float over the area needing to be reduced.
Was easy to get a nice, flat, clean looking concrete junction between the two adjacent concrete segments of my sidewalk.
NOTE: I tried to throw some dollars at local area businesses but their product selection and pricing was just too high.
When I went to Home Depot, I saw only the well known brands like Bosch, Dewalt, Milwaukee cupping wheel grinder pieces.
However, the prices on those also were "premium", starting at like $50 and going up from there.
- cheaper than name brand cupping wheels
- seems to last quite a long time, even when working with cement and/or concrete
- arrival was a mixed bag. Supposed to be available for receipt by week's end, but then was told it would be a few days later. Ultimately it arrived a couple days earlier than the "will be late" message indicated.
Final result: arrived like a day later than first indicated, in time for my needing it, so not a problem for my needs that week.
- can wear down a bit faster if you bear down on it quite a bit. (Another family member took a more aggressive approach than I did and while they finished removing concrete faster than I did, the blade wore down a bit more than when I used it).
- it's probably been said in a thousand places online, but these cupping wheels and use on cement/concrete WILL produce a ton of dust.
When I used it, we were outside and had a nice strong wind. So we just setup upwind from the grinder's dust output. Usage inside a building would definitely benefit from some sort of vacuum system for dust.
- previously when helping a relative install a new kitchen tile floor we used a large handled 9" scraper blade. Which was painful and slow going.
I hadn't known about diamond cupping wheels those many years ago.
Next time we re-tile, I will try a cupping wheel like this to remove old tile, adhesive, grout, etc.
It did create a huge mess, but that's because I used a 4.5" angle grinder rather than a larger tool that can contain the dust. I tried to work wet, but I found that only worked for a few seconds and then the area would dry out and dust would fly anyway. I suggest using plenty of protective equipment, especially a face mask, and seal off the area you are working in to contain the dust cloud. Also set up fans to suck the dust out of aa window if possible.
This grinding cup also did not fit that well on my grinder. As others have noted, its a slightly different size that a standard US 4"/4.5" grinder, although it does come with the washer to adjust it to the correct size. Since it is concave, the disk that holds the grinding attachment on clamped down on the curved surface of the grinding cup, if that makes sense. This combined with the size difference made the grinding cup a tiny bit wobbly on my grinder. During use it wasn't a problem, when you put pressure on it the cup sits flat to the floor regardless.
Overall it did its job very well, at half the price of a similar product at the nearby home improvement store.
