Dorian Tool 73310101428 Cxa 71C Cut-off Tool Post Holder

Product Description

The DORIAN TOOL 73310101428 is a Series CXA carbide combination cut-off tool post holder designed for use on engine lathes with a swing range of 14 to 17 inches (350 to 430 mm). Holder number 71C accepts blades from the 26-2 through 26-6 range and accommodates blade sizes from 0.0630 to 0.2030 decimal inch (1.57 to 5.16 mm). The overall height is 2.25 inches and the overall length is 3.75 inches, with a centerline height of 1.6252 inches. This holder is installed by machinists and toolroom technicians requiring a rigid, repeatable cut-off setup on CXA-series quick-change tool posts.

This holder is suited for production and job-shop lathe environments where carbide combination cut-off tooling is required. It fits lathes with a swing in the 14 to 17 inch range and mates with standard CXA quick-change tool post systems. It does not include through-coolant capability, making it straightforward to set up in dry or flood-coolant applications where direct nozzle delivery is used. The 71C designation identifies it within the CXA series lineup for fast cross-referencing when ordering replacement or additional holders.
