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.
And correct me if I'm wrong but a keyed chuck is the exact same mechanism, the only difference is you're using a little gear connected to a big fulcrum lever (key handle) to turn it a little more than you can by directly turning the collar by hand (keyless)Doesn’t make sense to me, but I’ve never studied them. I assume they are a typical thread which activates the linear wedge motion of the jaws, so anything in the opposite direction would be counterproductive. Maybe the logic is that having it against a detent would be better than freely floating between the detents, but you could do the same by keeping it tight I would think.
This has always made me wonder - why dafuq do we make them this way? Why not have the chuck spin the other direction so that it gets tighter as it is pushed back against the work?Doesn’t make sense to me, but I’ve never studied them.

Are they not? All of mine areI don't understand why all bolt extractors aren't left handed.
Sorry I misspoke. The extractors themselves typically are but the bits that come with them to get them started often are not.Are they not? All of mine are
You have been darn lucky! I usually get stuff already fubared with broken tools in it or similar to the Titanic in terms of corrosion.Sorry I misspoke. The extractors themselves typically are but the bits that come with them to get them started often are not.
I never use conventional extractors anymore. Just lefthanded bits.
Thhere's nothing worse than when you get an extractor or other tool broken off in the thing you were trying to extract... nwo you have schucnk of hardened tool steel in the way to deal with. Thats when the real cussing starts.You have been darn lucky! I usually get stuff already fubared with broken tools in it or similar to the Titanic in terms of corrosion.
