2.5″ 4-Jaw Independent Chuck Body – Various Thread
-
Independent chucks can be used to hold irregularly shaped parts, center parts with a great deal of accuracy and hold a part off-center. They can clamp stock tighter than self centering chucks. This is a valuable asset when machining cams, crankshafts and similar parts. The main disadvantage of the 4-jaw independent chuck is that the jaws must be set individually, adding considerable setup time. The jaws are reversible to accommodate larger stock.
