Description
The 4 jaw chuck is the most versatile of all the chucks. It can hold round and square shaped materials. Unlike the 3 jaw chuck (self centering) each jaw on the 4 jaw chuck is adjusted independently of the others.
Some features of the 4 jaw chuck are
- Hardened steel jaws with steps
- Reversable range 1/8 to 3 1/4 inches
- Jaws are independently adjusted in pairs
- Setting a workpiece off center creates crankcase and cam shapes
- Parts may be machined to run very true (this will require more time to center than a self centering 3 jaw chuck)
