There are two types of 4 jaw lathe chucks: self-centring lathe chucks and independent lathe chucks.
In self-centring 4 jaw chucks, the jaws move in unison when you turn the knurled ring. Because the jaws move together, the workpiece can be clasped quickly into place. Self-centring chucks are primarily used for square stock, with the interlocking movements of the jaws perfect for rapidly gripping square stock and certain types of round stock.
4 jaw independent chucks have four separate jaws that can be adjusted to grip onto a workpiece. This offers significant advantages. You can use a 4 jaw chuck lathe to safely hold square, hexagonal, wound, and irregular-shaped workpieces, with the independent movement of the jaws enabling accurate adjustment. The pay-off is that they are more time-consuming to set up and configure.
The jaws themselves on both types of 4 jaw chuck lathe can be reversed so that they can hold workpieces by the inside diameter. This offers a much higher range of operation.
