Sherline 2.5 Inch 4 Jaw Independent Chuck 12 x 1mm 1071

Description: Sherline 2.5 Inch 4 Jaw Independent Chuck 12 x 1mm 1071 Sherline 2.5 Inch 4 Jaw Independent Chuck 12 x 1mm 1071 4 Jaw Chuck 12 x 1mm Sherline offers their 3.1″ 4-jaw self-centering chucks with a 22 x 1.5 mm threaded hole for use on Sherline’s optional ER-16 spindle nose. Also for use with certain other ER-16 spindles that use the 22 x 1.5mm thread for the collet nut. These chucks have four advantages over 3-jaw chucks. Useful for holding irregularly shaped parts With the use of a dial indicator, center parts with a great deal of accuracy Useful for deliberately holding a part off-center They can clamp stock tighter This is a valuable asset when machining cams, crankshafts and similar parts. The main disadvantage of the 4-jaw independent chuck is that the jaws must be set individually, adding considerable setup time. The jaws are reversible to accommodate larger stock. Like the Sherline 3-jaw chucks, the 4-jaw chucks can be used to clamp either externally or internally. Although we recommend the 3-jaw chuck for standard lathe projects, the 4-jaw chuck is considered the accessory that could add the most versatility to your machine. If you feel the 4-jaw chuck would be more useful, and you have no need for the 3-jaw chuck, any lathe “A” package can be ordered with the 4-jaw chuck substituted for the 3-jaw upon request. A clamping groove allows the chuck to hold parts for milling. Jaw Options 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). Add the note “loose jaws” when you order 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) Like the Sherline 3-jaw chucks, the 4-jaw chucks clamp either externally or internally. The spindle thread for this 2.5 chuck is 12mm x 1mm to fit other brand machines. A hex key will tighten each jaw individually. Tommy bars are used in the holes in the side to tighten and loosen the chuck for more leverage. A groove is around the base of the chuck so that angle clamps can mount it to the table of a mill as a holding fixture.
