This die grinder is very powerful and smooth. I run it at around 110 psi from a small 20-gallon 110V compressor and it works great. Because the tool uses between 20 and 34 SCFM, I can’t run it for a long time. Every now and then, I have to give the compressor a break so that it can keep up. The small size makes it easy to get into small places and move it around a complicated piece of work.
American standard 1/4” and metric 6mm collets are included. If you buy burrs and bits from other countries, you can put them in the chuck with the help of these two different sizes of collets. Other tools I have that are only 1/4 of an inch long “On a 6mm rotary burr shaft, it’s often not tight enough. This one is great.
With it, you get two chuck wrenches. One of them is at an angle, so you can hold it and the tool in one hand while tightening the chuck with the other wrench. A very clever idea.
People who own these tools don’t see any mention of a “built-in regulator,” which is a part of the tool description. I have shown you a picture of it. If you turn the inner screw, the tool changes its speed to match. This is very useful when you’re driving something like a wire brush so it doesn’t go too fast and throw wires all over the place. In order to control, you have to be very careful. There’s a little knob on the regulator that lets me slow it down to a crawl or speed it up to 27K RPM with a little turn.
You should wear hearing protection if you plan to use this tool for a long time. The rear air discharge is diffused and out of the way. It doesn’t blow chips around.
The air tool needs a few drops of oil before you use it and a lot of clean air in the shop. It will work all day. Well-made, heavy for its size, and powerful. There is a lot of value in the quality of the fit and finish at a very low price.
