divider 1 Differences Between Three-Jaw and Four-Jaw Lathe Chucks

There are several differences between lathe chucks with three and four jaws. Take a look at some of them below.

Construction and Motion

The primary difference between these two lathe chucks is in movement. Three-jaw lathe chucks are connected using scroll gears. It’s a self-centering chuck and the jaws move simultaneously.

On the flipside, jaws move independently in four-jaw chucks, and you have to center the workpiece.


Four-jaw chucks hold a workpiece in the form of a hexagon or a circle. On the other hand, the three-jaw chuck holds a workpiece in the form of an octagon or a square.

Number of Holes

In the three-jaw chuck, the chuck wrench has only one hole or key. It loosens or tightens the grip. On the flipside, four-jaw lathe chucks come with four holes. They regulate every jaw.

Setting Time

Setting time is the time it takes to rotate a tool or spindle in a drill chuck. Setting up four-jaw chucks takes longer than three-jaw chucks. But a four-jaw chuck can do more than three-jaw lathe chucks.

Gripping Power

Another primary difference between the two lathe chucks is the gripping power. Four-jaw lathe chucks have higher gripping power than three-jaw lathe chucks.

Weight of the Workpiece

The workpiece weight is crucial for the lathe chuck design. A heavier workpiece needs a heavier chuck to ensure it has enough support.

The three-jaw chuck holds small workpieces such as nuts, bolts, and screws. It also has a smaller capacity than the four-jaw chuck. The four-jaw chuck grips large items such as drill bits and chisels.

Here is a summary of the differences between three-jaw and four-jaw lathe chucks:

Three Jaw Lathe Chucks

  • Jaws are connected
  • Grips square and octagonal workpieces
  • One hole
  • Short setting time
  • Less gripping power
  • Supports light and small workpieces
Four Jaw Lathe Chucks
