About the Interchangeable Jaws
Brass top jaws with bottom master jaws.
Certain delicate parts require gripping with softer jaw materials. Other operations require chuck jaws that do not transmit particles of rust to the part being held. To accommodate these special circumstances, Sherline now offers 2-piece chuck jaws with interchangeable top jaws made from special materials, and bottom master jaws*. In place of the standard hardened or optional unhardened (“soft”) steel 1-piece jaws, these new top jaws are .600” tall and come in soft materials like Delrin, Teflon, and Nylon, plus harder but non-rusting materials like brass and aluminum. The replaceable top jaws are fastened to the hardened steel bottom jaws with two countersunk socket head screws. They are not stepped so the customer can machine them for custom holding applications. Other materials are available by request.
*Please note that you must purchase the bottom master jaws before you can use the top jaws.

Tall Top Jaws
We also offer taller jaws with heights of 1” and 1-1/2”. The tall jaws are made of aluminum and mild steel. These taller jaws were developed for a customer who uses our lathe for custom jewelry design and can be machined to hold custom work, as seen in the photo to the right.

NOTE: To customers who are buying these jaws for an existing chuck, please measure the width of your current chuck jaws with a pair of mics so we can grind your master jaws to match. State your current jaw width in the comments box above. For first-time buyers who are buying a new chuck with these Master jaws, your jaws will be ground to match your chuck. The prices shown are for the jaws only (new chuck is not included).
