Aloris CA-54 Morse Taper Tool Post Holder 4MT Series Ca

Product Description

The ALORIS CA-54 is a Morse taper tool post holder designed for use with Series CA quick-change tool post systems on engine lathes. It accepts a 4MT taper shank, allowing machinists to mount drill bits, reamers, centers, and other Morse taper tooling directly in the tool post without removing the tailstock. The holder stands 2.5 inches overall height with a centerline height of 1.25 inches, placing the tool on center for lathes with a swing of 14 to 20 inches. At 6.25 pounds, the holder is built for rigid, repeatable positioning during turning and boring operations.

This holder fits engine lathes in the mid-size range, specifically those with a 14 to 20 inch swing, when equipped with a Series CA quick-change tool post. Typical applications include production turning, job shop work, and toolroom lathes where operators need fast, repeatable tool changes between Morse taper tooling and standard turning tools. Through-coolant is not supported on this holder.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and bring the lathe spindle to a full stop before changing or seating any tool post holder. Ensure the Morse taper shank and the holder bore are clean and free of chips or oil film before seating to prevent fretting or taper slip under load. Confirm the tool centerline height matches the lathe spindle centerline before taking a cut.
