I can concur with the previous reviewer. The exception is we gave Jooltool a call and they replaced the bad abrasives-explained it was a rare occurrence because they only use 3M industrial abrasives and that 3M was replacing the products as they found them... bad batch happens to the biggest of them I guess!

Anyway we also made a change of the abrasives we were using and we could not be happier!

Cal OSHA but love these because they are way safer than a bench grinder... we actually have two Jooltools one dedicated for horizontal use on larger items and one set up vertically for the Ninja discs... We're thinking of getting a third so we can have one with the flex shaft set up all the time-beats the hell out of a dremel!

Thanks Jooltool!

Overpriced....... Had to buy pack of 4 assorted, only needed the coarse grit. Was only able to sharpen one flute on a 2" diameter router bit before the abrasive wore out. I followed JoolTools videos on u-tube. Will keep looking for a better way to sharpen my router bits.

First off I'd like to say that I probably use this tool more than it's rated for. I use it to polish Koroit Opals. The Flexible diamond abrasive, that they only sell on their site, works really well in sanding down the stones. I then follow up with the microfinishing abrasive. Since March, I have purchased FIVE sets of these. They aren't built to do what I need them to do. If you were only working on about a dozen stones a month it might be ok. At this moment I was putting on a new set of abrasives when I decided to write this review. The first two sets worked well. Then the third and forth started breaking down faster. This last set is cut weird and do not fit on the backpads. If you really want to try this machine for whatever purpose buy it used if you can. I wish I hadn't bought it at all. I've spent enough money with JoolTool. I now have a Diamond Pacific Bigfoot and wish I had bought it first. I could have bought a Genie if I didn't waste all this money on the JoolTool.

Expensive. As a replacement, the cost should be less. The offerings of the products outweigh the usage. Best for sharpening knives and cleaning.
