So is the Beall really worth twice the price of the PSI for the complete system? I'm getting ready to buy a full set but I just can't figure out why the price is so different beyond just brand name.
Can anyone give me the rundown?
Also with a collet chuck, do you have to be the exact size of the collet? i.e. 3/4 will only clamp on 3/4 or will it clamp down on slightly smaller as well.
Thanks!
Here is my take, I have both the Beall and PSI chucks;
I like the Beall best, it offers a smaller nose area to get in a little closer with your hands and tools. The PSI knurled ring is a lot bigger than it would need to be to be functional, and it gets in the way a bit.
I have a slight issue with vibration with the PSI above 1000 rpms, also.
The Beall runs butter smooth, no matter rpm.
Price difference is where it's made, likely. and the quality specs given to manufacture. I think the Beall is a tad overpriced, but am happy with mine and would recommend them to anyone.
These both take ER32 series collets, and the collapse range is generally specified at 1mm maximum, (.03937 inches).
Never ever expand a collet. it is a recipe for runout, and it can cause breakage.
So, a 3/4" collet will chuck from .750 down to appx. .710.
