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

Sherline 2.5 Inch 4 Jaw Independent Chuck 12 x 1mm 10714 Jaw Chuck 12 x 1mmSherline 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 partsWith the use of a dial indicator, center parts with a great deal of accuracyUseful for deliberately holding a part off-centerThey can clamp stock tighterThis 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 OptionsFor 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 orderChucks for Sherline and Other LathesThe 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 internal
