This set is mine. When I first used it, I found that the only thing included in the "kit" was a hex wrench to loosen/replace the pilot jet. The 5/64" wrench needed to loosen the yoke to insert the drive pins into the hole saw is NOT included. That's ridiculous. The tools REQUIRED to use this hole saw set are NOT included. Unacceptable. A 5/64" hex wrench can be used but is included. To have one working with this kit I have to BUY a wrench to use the $100 hole saw kit.
