Depends on the tool. They have multiple suppliers.
IR
Chicago Pneumatic
Florida Pneumatic
Professional Tool
Most of the blue plastic colored ones seem to be supplied by the latter two companies.
Well, I don't know who makes it, but I just snagged a new CAT520 for $39.99 shipped. It lists on the Cornwell site for $120.
I was really looking for an angled die grinder, something compact, but this is a full size. I couldn't pass it up for the price. I surely could have used it today when I was cleaning up gasket surfaces on a head and block with a red Scotch Brite pad, brass wire wheel in an angle grinder, acetone and a rag. That took waaaayyy too long.

They are made by Professional Tool Products, and they are well made and durable. I would say you have bought a bargain.

Where did you happen to get this $39.99 deal on said air tool bull? You have me interested.
