Product Description

The DORIAN TOOL 73310101554 is a Series CA Number 2 Boring, Turning, and Facing Tool Post Holder designed for use on engine lathes with a swing range of 16 to 20 inches.

The shank size is 3/4 inch, and the holder accepts cutting tools up to 1-1/4 inches. This holder is intended for installation by machinists and toolroom professionals working with compatible quick-change tool post systems.

This tool post holder is suited for general-purpose turning, boring, and facing operations on mid-size engine lathes. The Series CA designation identifies it as part of a standardized quick-change tooling system, making it appropriate for production and job-shop environments where consistent tool height and rapid changeover are priorities.

Installation Notes

Installation should be performed by a qualified machinist with the lathe fully powered down and brought to a complete stop before any tooling changes. Verify that the tool post and holder series match before mounting to ensure proper seating and centerline alignment. Follow the machine manufacturer guidelines for tightening hardware to avoid distortion of the holder or tool post dovetail. Confirm cutting tool height at centerline before resuming operations.
