    I have a set of holesaw with screw on mandrel, and every time I use one of the bigger sizes the damn thing gets stuck, and need a wrench or impact driver to separate them. Tried to oil the threads but didn’t help at all.

    Other than getting a set with quick attach mandrel, any ideas on keeping it from happening to begin with?

    So your mandrel doesn’t have a sliding collar like this?

    Same darn issue here. I have two hole saws permanently set up because the mandrels seized a long time ago

    No I don’t have the collar and the two pins to hold hole saw in place, the mandrel screws onto the hole saw until it bottoms out.

    Try an impact driver with right sized socket for the hex shaft, makes removing it a lot easier.

    That type just gets tighter when you use them…nature of the beast. The quick connect type a better about this, but the plug can still get stuck.

    I used to have the same issue with an older hole saw set that I used but ever since I switched to the DeWalt set I haven’t had any issues since it has the pin system and seems to release pretty easily. Having said that I haven’t been super impressed with how the DeWalt set cuts, the teeth clog up pretty quick. I’ve borrowed a Lennox set before and really liked that.

    Do you drill relief holes to let the sawdust fall out? If not that could help.

    I do the same thing with that style hole saw. I got fed up using a vise and a big bar to get the mandrel free. The pin type is so much easier. I think the screw on style is the “economy” version for some mfg’s.

    No I haven’t but I should try that. The Lennox set that I used was by far my favorite, it cut super quick and no plugging with sawdust. I’ll try the relief holes next time I use my set and see if it helps, thanks for the tip.

    I have to agree about the Lenox saws. They are top notch. If a plug gets stuck in the saw it is easily leveraged out with a screwdriver…other brands claim that they are easy to clear, but only the Lenox actually makes good on that claim, IMO.

    That design is the only one that won’t stick . It’s the best way to change hole saw bites . I only buy Lenox .

    Always willing to learn .

    Does anybody have any Bosch hole saw sets?

    Yes, the fix to this problem is the new arbor with the two pins.
    I have the Milwaukee hole saws, they have a lifetime tooth warranty so if I break a tooth I get a new saw.
    @doobie I just got some recently but have not had the chance to use them yet. The multi constructions saws I got have a 1/2 inch quick change arbor with no threads.

    I was gonna redeem for some of their sets at one point, but I ended up seeing a good deal on a Milwaukee set a few months back.

    I’d love one of those carbide multi-construction sets, but they are super expensive and very limited in sizes.

    Bosch does have a bi-metal set.

    I have a set of Milwaukee hole saws with the pins in the collar, sold the olds ones at a lawn sale after getting them.

    I found a couple sizes on eBay for pretty cheap, I think they were less than $20

    You can try a small dab of anti sieze lube on the threads but in reality you just need to go buy the better quick release arbor. It was invented to solve this exact issue.

    I wouldn’t mind one either. Bosch does make good cutting tools of all types.
