Sorby Patriot Chuck

The Patriot is a precision 4-Jaw self-centering scroll chuck made in England by Robert Sorby. The chuck uses a single tilt-away wrench that allows even larger workpieces to be tightened easily. The design of the gearing insures smooth jaw travel for the life of the chuck. A wide range of optional jaws are available.

The Patriot Chuck includes 2 (50mm) jaws that feature a smooth dovetail on the inside and outside. The lower section of the inside has serrations for a better grip on larger workpieces. The 2 Jaws will hold:

Grips: 1-9/16 (42mm) to 2-5/16 (67mm) Expands: 2 (50mm) to 3 (76mm)

This chuck features:

  • 4" Diameter with enclosed back
  • 4-Jaw Self-Centering Scroll Action
  • Precision machining for smooth operation
  • Single Key tightening with Tilt-Away wrench design for larger work pieces
  • Unique Rubber Guard protects the operator
  • Gearing make a secure grip easy to achieve
  • Includes Screw Center for mounting a work using a single pilot 11/32" hole
  • Weight: 4-1/4 pounds

The Patriot Chuck comes standard with a screw center that permits mounting a workpiece easily with an 11/32 diameter pilot hole.

The body of the 33mm Patriot Chuck is threaded directly to fit a 33mm x 3.5 lathe spindle only. This version of the chuck does not use an insert, unlike both the Standard Patriot Chuck and the Compatriot Chuck.
