We hadn’t paid a great deal of attention to Bosch’s quick change hole saw system until we saw it in action on their website. The sweet video demo displays what the quick change system is all about.
From what we saw, it’s pretty simple to snap in a new cup to whatever pilot bit is already loaded into the adapter, so you’re ready to go in no time flat. Of course, you could always carry around a bunch of hole saws with the pilot bits already in them, and re-chuck them when you want a different size — but this seems faster.
The complete quick change hole saw system will run you around $110.
