H&R Mfg 82-3.5 Serrated Soft Lathe Chuck Jaws 4" OAL 1-3/4" OAW Set of 3

This is a new, factory-sealed set of 3 H&R Manufacturing model 82-3.5 soft steel lathe chuck jaws, sourced via MSC Industrial Supply (MSC #99558421). The jaws feature a serrated (knurled) top surface on the mounting face for positive location and repeatable positioning when bolted to master jaws, with two mounting holes per jaw spaced 1.181" center-to-center. Each jaw measures 4" overall length (OAL) and 1-3/4" overall width (OAW); the "3.5" in the part number designates compatibility with an 8" chuck (approximate chuck size designation used by H&R Mfg). Soft jaws of this type are machined by the end user to a specific bore diameter, making them suitable for precision chuck work on CNC and manual lathes where repeatable, damage-free workholding of finished or delicate parts is required.
