A 4-jaw independent chuck can be identified by having four separate jaws, each with its own adjustment screw and keyhole so that each jaw moves independently. Unlike a 3-jaw scroll chuck (where all jaws move together), a 4-jaw independent chuck does not have a central scroll mechanism and allows precise adjustment—ideal for irregularly shaped workpieces. To confirm, count four jaws, check that each moves alone via its dedicated keyhole, and note the absence of a mechanism linking the jaws. This type of chuck is commonly used for high-precision or off-center work on a lathe.Please read for details《How to id a 4 jaw independent chuck》
