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.

    I recently bought a the cheaper and simpler Dewalt quick change mandrel. The saws have a threaded center hole that spins onto the mandrel, then a pair of spring-loaded pins lock the saw in place. It’s not as quick as the Bosch system, but it’s less expensive and the saws are less bulky since the don’t each require their own quick change adapter to make them work with the system.

    I tried the dewalt rig and it doesn’t work with other competitive cups. So, I could only buy dewalt cups and hardly anyone carries them.

    The Bosch works with almost every cup and as I mentioned in the previous hole saw post, their carbide cups kick ass!

  3. The video does a pretty good job of showing the quick change system, but I got a little tired of the announcer constantly selling and using marketing speak. Just show us what your product can do and if it’s a good product we’ll buy it already.

    Drive pins are nothing new on hole-saw mandrels – and sometimes getting the plug out is more time consuming than any quick change. Feed rate for hole saws is also notoriously slow and requires steady feed pressure.

    As I’ve previously commented – if you are boring joists/studs and want to speed up the process of drilling the hole – not just changing the hole saw – then use selfeed bits with an appropriately sized drill. We have holesaws on our plumbing trucks – but hardly ever take them out for rough-in work.

    For steel door hanging – our carpenters will say that’s a different kettle of fish.

    By the way – we’ve been doing more fiber cement siding lately – and think that the Bosch carbide tipped hole saws are great for this application

    I have several sizes of Starrett holesaws that I’ve had for over 20 years that look quite similar to the DeWalt mentioned by BJN.

    PS: 4 1/4″ is perfect for dryer vent

    Most of ours are probably Starrett bi-metals too. We use their carbide grit edged holesaws for installing access holes for plumbing in tilework. The mandrel for these includes a carbide-tipped center drill bit.
    Hitachi makes similar tools – and Dewalt has some with diamond grit.
    My electrical sub – likes really big Rem-Grit and Greenlee hole saws for cutting in recessed ceiling fixtures

    Hole saws work best for thin wood, sheetrock, plaster, metal framing studs/joist.

    Another good use is for notching hard/tough spots. Holesaw a few times in area, chip out with chisel or big screwdriver.

    I use other bits for rough-in boring. Sometimes holesaws for flooring too.
