02a) Micro Lathe 4 Jaw Chuck 80mm Diameter 22x1.5mm Threaded Mou

Micro Lathe 4 Jaw Chuck 80mm Diameter 22mm x 1.5mm Threaded Mount

4 jaw 3 1/4" dia. chuck 22mm x 1.5mm threaded mount; jaws adjusted independently (reversible heat treated steel jaws).

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"
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)

Thread size 22mm x 1.5mm
