Review on Astro 1221 Grinder Rotary Burr by Jesse Azuse

These tools work as advertised. I like the small size for accessing bottlenecks and the performance was excellent. I'm new to using pneumatic tools so I had a bit of a problem getting the bits into the tool. I didn't have a thin wrench to hold the spindle while tightening the nut. I believe that should come with the kit as I'm sure a lot of people don't have a skinny wrench. I could make a wrench but it would be nice if it came with it. Otherwise I am happy with the purchase and have found the Astro Pneumatic Tools to work as advertised.
