Chris Chris' Tips
In 2011 I visited the factory that makes these air tools in Taiwan. We saw a great demonstration of world-class manufacturing. Every step is documented and the workers always have the book in front of them. Quality checks are made at each step in manufacturing.

They make tools for all the big names in air tools (including LittleMachineShop.com?).
