I purchased all tools new (in a kit)for a home built airplane project. They saw minimum use (quick build kit, 1/2 completed). They have not been used in awhile so I put a drop or two of oil in them and tested. They operated just as last time I used them(very good). There is approximately $2000 worth of tools but I have no need for them so selling. I know there is probably a better forum to sell but figured I would try locally first(maybe a RV builder in the neighborhood). These tools are a steal at $550. Includes ever thing in pictures. Please don't hesitate to ask any questions.
