Three-jaw chucks are designed so that all three jaws move together and automatically center round or hexagonal parts or stock to within a few thousandths of an inch. These chucks provide the quickest and easiest way of holding work in the lathe. For this reason, they are the most popular of the Sherline accessories. The Sherline 3-jaw chucks are designed so that they can be used to clamp externally on bar stock or internally on tube stock. The jaws are reversible to accommodate larger stock.
Chucks for Sherline and Other Lathes
The chuck is available in several spindle threads for use on Sherline (3/4-16) and other machines such as old Unimat lathes (12mm x 1mm and 14mm x 1mm) or Sears 6″ lathes (1/2-20).
*Please note that chucks with a thread size other than 3/4″ x 16 are made to order and have a lead time of 5-7 business days.
- For those who have jobs where speed and ease of use are more important than maximum accuracy and want a chuck that is loose right from the start (No extra charge).

- Soft (not hardened or machined) steel jaws are also available when you build your own chuck.
