I said the other day that most air tools, no matter what brand you buy, are very rough on the edges. (but they still work reliably, probably because they're simpler than with motors). Then add that, and it's basically an exceptionally well-crafted, refined instrument. It seems to me that the new owners of Craftsman are bringing this name back to its former glory (for which they have a lot to thank). It's super smooth and has a kind of dual circuit system. I assume this is to ensure that the pressure (from the weight) on all parts of the disc is even over a period of time. But it inspires trust. And you set the speed with the airflow knob on the tool, which ranges it from so low it won't move to super fast. And it makes sense to use this function as it says in the manual in order not to damage the workpiece from ultra high speed. You can remove the spindle lock pad as expected. And as you can see, it works with the handle "trigger" system. Plus, it's still a simple tool. So if you take care of it, it will probably last forever. What they've done to make it a little more special is give it a very aesthetic rubber finish, molded for comfort and better detail (in the optics department). While I'm more interested in how the tool works, it's a nice change from very basic tools and feels like you're getting the best you can get. about it (ironic, I know). Unfortunately it's too deep for the lid compartment in my tool box where I keep my caseless air tools. So maybe a box would be nice. And of course 6" self-adhesive grinding discs are rarer than 5" velcro pads in my experience, but I think I like the 6" self-adhesive grinding discs more. Also, there is no option to connect a vacuum cleaner, certainly worth considering, but I usually prefer my air tools including this one when I have the compressor activated.
