What is the difference between the three jaw chuck and the four jaw chuck?
The 3-jaw has three jaws and the 4-jaw has four jaws.
What are Chuck Jaws products used for?
Chuck Jaws are used to make sure the things you drill in are really tight. These jaws help support the weight that normal screws just couldn't support.
What are internal lathe chuck jaws?
Internal chuck jaws are designed to hold the work internally whereas external jaws hold the work externally. If we use a cylinder as an example the internal chuck jaws would fit into the hole and apply outward presure to grip the work. External jaws would sit on the outside of the cylinder and apply preasure inward to hold the work.
What is a chuck?
The chuck has three, sometimes four "jaws" that grip the piece to be turned. On a power drill, the chuck holds the bit in place while it turns.
What is a lathe chuck and what are the types of chuck?
A lathe chuck is a device on the driven spindle on the head (headstock) of the machine that holds the workpiece. It grips and spins it. The chuck has "fingers" called jaws that "pinch" the workpiece between them to secure it. Chucks can be 2-, 3- , 4-jaw or more. And the chuck can be self-centering or of the independent type. The self-centering chuck will have a "scroll" of threads behind the jaws that engages them. The scroll is the screw that will close each of the jaws on the workpiece (simultaneously) with the use of a tool to tighten it. And this chuck will automatically center the workpiece in the chuck. Independent chucks will have jaws that must have a tool used on each of them independently to tighten them. And of course, the workpiece will have to be "fooled around with" until it is centered in the jaws. Workholding is a company that sells chucks and has an article with pictures. A link is provided to the site. Additional links are provided to other images. Be sure to at least look at the "6-jaw chuck taken apart" to see the scroll gear that simultaneously closes the jaws. Look closely. The shiney "circles" are not circles at all but are the gradually shaped spiral of the scroll.

What is a 3 jaw chuck on a lathe?
A 3-jaw chuck is the device attached to the spindle of the lathe that clamps and rotates the workpiece for machining. This type of chuck is self-centering which means that the three jaws move in unison at the same diameter when the chuck is opened or closed.
What is the purpose of a 3 jaw chuck and what shapes do they hold?
The three-jaw chuck is a self-centering device used on machine-tools like Lathes. It consists of 3 jaws, set on a round face-plate at an angle of 120 degrees to each other. Each jaw moves away, or towards the centre, taking the other two with it. In this way, the distance from the centre to the three jaws is always equal. The jaws can be rotated to grip work internally (example: a hollow cylinder) or externally (example a solid bar). Because of the geometry of the jaws, they can hold cylindrical work, triangular sections, hexagonal sections etc. For holding square sections or irregular sections, a 4-jaw, independent chuck is available.
