Dorian Tool 73310101062 Series Ca Tool Post Holder Set

Product Description

The DORIAN TOOL 73310101062 is a Series CA tool post holder set designed for lathes with a swing range of 16 to 20 inches. This 14-piece set provides a complete quick-change tooling solution for manual and CNC lathes in production and job-shop environments. The set includes four holders, four toolholders, five inserts, and a tool post, giving machinists a ready-to-run package. The base width measures 4 inches, and the bolt hole diameter is 22.23 millimeters. The set ships as a single package unit and is well-suited for shops transitioning to or expanding a quick-change toolpost system without sourcing components individually.

This set is intended for use on engine lathes and manual turning centers with a swing of 16 to 20 inches. It is appropriate for both production machine shops and toolroom applications where repeatable tool height and fast changeover are priorities. The Series CA designation indicates a specific holder size class within the Dorian quick-change toolpost system. Licensed machinists and toolroom technicians are the primary installers and users of this system. The included inserts allow immediate use on common turning and facing operations after mounting.

Installation Notes

Installation is performed by a qualified machinist. Before mounting the tool post, ensure the lathe is fully powered down and the chuck is secured or removed per shop safety procedures. The tool post stud should be properly torqued to lathe-manufacturer specifications found in the machine manual, not estimated. Verify tool height alignment with a reference gauge before running cuts, and follow OSHA machine-guarding requirements when returning the lathe to service.
