Air Grinder,4-Inch Air Wet Stone Polisher 5500 Rpm with Rear Exhaust,Air-Powe...

First off, this tool is excellent. I used it to finish the side edges on 7 pieces of quartz stone for trim accents around some custom showers I installed. I have used other grinder/polishers but this was a far better tool for my application. What I appreciated most was the lightweight nature of the tool. I used it with a 29 gallon air compressor. This was a little light for the application, if I had a bigger compressor it would have been better (less waiting between passes for the air pressure to increase). But it did the job and no one would be the wiser that I didn't hire this work out. Doing this on my own saved me a considerable amount of money on fabrication and after a few YouTube tutorials I was ready to go. A couple notes of caution - you likely won't be able to use this right out of the box unless you have a barbed adapter to connect to the fittingless end of the supplied water line. This was a bit of a frustration but was quickly remedied with approximately $10 in fittings from my local big box hardware store. Note I also splurged for a 10ft 1/4" water line hose so that I wouldn't have the weight of a garden hose hanging off the end of the tool. With my plumbing all sorted out I knocked out the work in less than 8 hours and general cleanup of the tool was a breeze. Definitely worth the investment.

great polisher for granite edge polishing,, i have purchased 3 so far and it works well......they last as much as the expensive ones....

This is a great value for the money. Works great and I really like the controls. Both water and speed levers can be moved with the thumb while operating the machine.

My crew and I typically use high-end Alpha brand polishers, with 5” backing pads. However, those are 3x the price. We specifically needed a wet-polisher that we could mount a router-head to, but didn’t want to spend $600 to do it. This litter polisher has held up phenomenally well with that 3/16 routing head on it, and has probably radius’d 1,000+ linear feet of concrete at this point! The controls, hose attachment, and center spindle are all identical to the Alpha models, so if you’re familiar with those you’ll be able to move over very easily. This polisher is a bit more compact than others, and weighs slightly less. Those could be a benefit, indicator of quality, or a detriment if you have big hands. To me, the size and weight differences haven’t seemed to indicate anything in particular.

The surface of the processed polished stone is very good in using, the noise is small, and it’s very efficient. Because of reasonable design of structure, so it’s very suitable for us to use in the stone processing process for a long time, the quality performance is superior, and it can finish well.

Ok

Powerful.
