Murray Split Die Thread Chaser Tool

The Murray Tools Split Die Thread Chaser repair system is designed to save you time and money. Because our hex dies are split and utilize our special spring design, you can place our metric and standard thread dies below the damages on your bolt or stud, then using a 6 point deep well socket, chase the threads clean. Our patented system is fast and easy to use, and because you start on clean, undamaged threads, you avoid cross threading.

Due to the ease of use and portability of this professional thread repair system, the Murray Split-Die is a must for repair kits and numerous rethreading applications.
