I have just received my AIRCAT 6275-A. THE SIZE OF THE DISTRIBUTOR IS 3/8, NOT 3/4 LIKE SOMEONE SENT. The tool runs quietly and is ideal for hard-to-reach places. Ideal for breaking metal and cutting welds. Very easy to cut straight lines with a smooth, clean cut. I already have an Aircat 90 degree grinder and a saber saw. Will buy more Aircat tools.
