Product Description

brass top-jawsCertain 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. In place of the standard hardened or optional unhardened (“soft”) steel 1-piece jaws, these new top jaws 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 they can be machined by the customer for custom holding applications. Other materials available by request. *Please note that you must purchase the bottom master jaws before you can use the top jaws.

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 when you place your order. For first time buyers who are buying a new chuck with these Master jaws, your jaws will be ground to match your chuck. Prices shown are for the jaws only (new chuck is not included). When ordering also state whether you are ordering jaws for a 3 or 4 jaw chuck.
