I do use a hole saw occasionally. good info thanks.Keyless chucks are nice for quick tool changes. They suck when using hole saw and the likes. They will lock up on you. So depends on what your primary work is going to be.
There’s a difference between a cheapo keyless and a good one like an Albrecht. Or course they can have problems too, but man they are so nice to use 99.99% of the time.I got an albrecht keyless chuck with my mill and it made me never want another keyd chuck. I think we have a Jacob’s keyless at work, it’s gotten locked up a time or two and had to be broken loose with a large pair of channel locks. They both seem to hold bits great even larger diameter.
