Dorian Tool 73310100006 Quick Change Tool Post 16-20in

Product Description

The DORIAN TOOL 73310100006 is an indexable quick change tool post designed for metal lathes with a 16 to 20 inch swing capacity. Built to Series CA specifications, this tool post provides a centerline height range of 1.75 to 2.50 inches and a tool post height of 7.525 inches, making it a precision fit for mid-size engine lathes. The 24-position indexing system allows for rapid, repeatable tool changes without losing reference position. At 35 pounds, the unit is built for rigidity under continuous cutting loads. Machinists and tool room technicians install this post as a direct upgrade over standard lantern-style tool posts.

This quick change tool post is suited for production and job shop environments running mid-range engine lathes. The 16 to 20 inch swing range covers a broad segment of manual metalworking lathes commonly found in machine shops, maintenance departments, and vocational facilities. The 3/4 inch bolt hole diameter fits the mounting stud found on lathes in this swing class. Series CA tooling holders are compatible with this post, allowing machinists to build out a holder set for turning, boring, threading, and cutoff operations without removing the post from the compound.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Before mounting, power down and lock out the lathe per shop safety procedures.

Torque the locking nut firmly against the compound to prevent movement during cuts, but follow the lathe and tool post manufacturer guidelines for final fastening practice.
