The Grizzly H7820 is a 4-jaw self-centering wood chuck designed for woodturning on lathes with a 1-1/2″ x 8 TPI spindle. Its dovetailed jaws hold work securely for small bowl and plate turning, helping users mount stock quickly and keep it centered during shaping.
This chuck grips wood in two ways: by clamping around the outside of a workpiece or by expanding into a turned recess. It requires a minimum diameter of 1-1/4″ for external clamping and 1-13/16″ for expansion, making it a practical choice for turners working on smaller projects.
Included accessories such as T-handled wrenches, a wood screw point, and a machined chuck lever make it ready for shop use. It is well suited for hobbyists, woodworkers, and turners looking for a dependable chuck for versatile small-scale spindle and faceplate-style work.
