MT5 Sliding Tailstock Die Holder Set (16–65mm) | Metric Lathe Threading Tool for Button Dies

The MT5 Sliding Tailstock Die Holder Set is a precision-engineered lathe accessory designed for accurately cutting external metric threads using standard button dies. Built for smooth operation and perfect alignment, this tool is ideal for both professional machinists and serious hobby users.

The holder features a Morse Taper 5 (MT5) shank that fits securely into the lathe tailstock, ensuring concentric alignment with the workpiece. Button dies are mounted in interchangeable die holders, which fit into the front of a knurled sliding sleeve. The sleeve moves freely on a fixed arbor, allowing the die to follow the thread naturally for clean, accurate results with reduced risk of cross-threading.

This versatile set supports three operating modes—free-hand mode for small threads, pegged sleeve mode for controlled cutting with larger dies, and stop handle mode for added stability when threading tougher materials under power.

Supplied with eight metric die holders (16 mm to 65 mm), this set covers a wide range of threading applications, making it a reliable and efficient solution for workshop and production use.
