The best dual action grinder money can buy. I have a 7/32 model and a 5/32. Both are used professionally and you won't hear me complain. Minimum vibration for pneumatic tools. Fits well in the palm of your hand. Aside from the cheap feel, especially for a Hutchins product. These tools are amazing for the money. 7/32 is good for feather edges and liners. In addition, the 5/32 is so well balanced that you will never feel uncomfortable next to the lines of the body.
