The Sherline 3.1 inch 3-Jaw Chuck is a larger chuck that takes up no more center-to-center space than the 2.5 inch chuck, but it will hold larger work. It has a clamping range of from 3/32 inch (2 mm) up to 1-1/2 inch (38 mm) diameter with the jaws in the normal position.

With the jaws in the reversed position, work up to 2-3/4 inch (70 mm) can be gripped. The hole through the chuck is 0.687 inch (17 mm). Rotating the knurled ring closes all three jaws simultaneously to quickly grip round or hexagonal stock.

Tommy bars (provided) are used in the holes in the side to tighten and loosen the chuck for more leverage. The chuck has a 3/4-16 thread to fit Sherline’s spindle.

CAUTION: These chucks are not intended for use at speeds above 3000 RPM.

  • 1 x 3.1 inch 3-Jaw Chuck
  • 2 x Tommy bars
