The three-jaw powered chuck is the standard work holding device for most  lathe users. This type of chuck is versatile enough to be used in a wide range of turning applications. However, it's not the best chuck for all jobs. The Collet chuck is an alternate work holding device that, like the jaw chuck, also uses mechanical force to hold the part being turned. While a Collet chuck lacks the capacity for the same wide range of work piece sizes that a jaw chuck can accommodate, it offers advantages related to speed, accuracy and productivity that may be crucial for certain jobs.

Collet chucks cater for standard stock material such as 6 mm, 8 mm etc round bar.
