Metal Lathe round threading die holder

This 3D model features both MT1, MT2 and MT3 mandrels for alignment in lathe threading operations. The threading die holder is for standard round dies.

A threaded insert and holding screw provide reliable retention of the die, preventing unwanted movement or slippage during threading operations.

Knurling has been added to the holder's surface to improve grip and user control

The design balances durability with ergonomic convenience, making it ideal for applications requiring precision and repeatability.
