H&R Manufacturing HR-112-2.0 Serrated Lathe Chuck Jaw PK3

H&R Manufacturing HR-112-2.0 serrated lathe chuck jaws are precision-ground hard steel clamping elements designed for three-jaw lathe chucks. The part number 112-2.0 decodes as part 112 size 2", providing aggressive grip without marring workpieces in high-production setups. New in original factory packaging from MFG Supply, Inc., this three-piece set features hardened steel bodies with evenly spaced serrations for repeatable clamping and minimal runout. These jaws are commonly used in manual and power lathe operations for holding round, hexagonal, and irregular stock 2" diameter chuck configurations. H&R Manufacturing is a specialized producer of replacement chuck jaws and toolholding components; these jaws are direct replacements for standard three-jaw independent or self-centering chucks marked for 112-2.0 specifications.
