Dorian Tool 73310101290 Bxa Dovetail Drill Chuck Holder

Product Description

The DORIAN TOOL 73310101290 is a BXA series dovetail drill chuck holder designed for use on engine lathes and toolroom lathes equipped with a quick-change tool post system. It mounts to the tool post dovetail and secures a drill chuck for axial drilling operations performed at the tailstock end of the workpiece. The holder measures 2 inches overall height and 4.175 inches overall length, with a centerline height of 1.313 inches. Maximum cutting tool size is 1/2 inch. This is a precision-machined component installed by machinists and tool and die professionals in production and job-shop environments.

This holder is suited for BXA-size quick-change tool post systems used on lathes with a swing range of 13 to 15 inches. It is the Number 35 holder in the BXA series, which corresponds to the dovetail drill chuck holding application. Typical installations involve mounting the holder to a BXA-compatible quick-change post and securing a keyed or keyless drill chuck for center-drilling, spot-drilling, or through-hole drilling operations on turned parts. No through-coolant capability is included in this holder.

Seat the dovetail fully into the quick-change post and secure the locking mechanism before initiating any cutting operation. Verify centerline height alignment with the lathe spindle axis before use.
