[QUOTE] The cheap die grinders are *really* air hungry, (so quite expensive to run compared to electric ones) as are most cheap air tools,[/QUOTE] I guessed as much but beggars etc .. [QUOTE] but I had a shiny new Snap-on mini D/A delivered today that uses a mere 2.2cfm @ 100psi. 15000rpm and less than 4mm of "swirl" and it's the quietest air tool I've used. Sweet. My Clarke (Machine Mart) die grinder uses around 10cfm (much the same as yours) and gives me a fucking headache when use it.[/QUOTE] I can't say the tool itself was that noisy as such and it also worked pretty well. [QUOTE] I must say though, it's been as reliable as fuck. 7 years of regular use and nothing more than the occasional squirt of oil.[/QUOTE] Nice. My idea was to test the concept of these tools via the cheapos then buy decent ones as / when / if it turns out I couldn't live without said. Today daughter was working on her MZ (taking off the small / broken screen, replacing the Kawasaki master cylinder with a genuine one) and I nearly fired up the compressor to try the air wrench but remembered I still need to get the PCL connectors.
