Dorian Tool 73310101424 Cxa Morse Taper Holder

Product Description

The DORIAN TOOL 73310101424 is a CXA Series Number 5 Morse Taper Holder designed for use on engine lathes with a swing range of 14 to 17 inches. It accepts a 4MT (Morse Taper Size 4) tooling bore and mounts to a compatible CXA quick-change tool post. The holder stands 2.25 inches tall overall with a centerline height of 1.625 inches and measures 4.156 inches in overall length. Weighing 4 pounds, it is built for rigidity in turning, boring, and taper work. Machinists and toolroom technicians install this holder as part of a quick-change tooling setup to reduce tool changeover time at the lathe.

This holder is suited for manual engine lathes in job shop, toolroom, and production environments where a CXA quick-change post is in use. The 14 to 17 inch swing range makes it compatible with mid-size lathes common in trade and industrial settings. It does not include through-coolant capability, making it best suited for dry or flood-coolant applications where coolant is delivered externally. The 4MT bore accommodates standard Morse Taper 4 tooling such as drill chucks, arbors, and live centers.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Always power down the lathe and come to a complete stop before mounting or removing tool holders from the post. Ensure the quick-change tool post dovetail and locking mechanism are clean and free of chips before seating the holder. Verify taper bore cleanliness and seating before securing any Morse Taper tooling to prevent runout or tool ejection during operation.
