Die Holder 20mm for M3-M6 Round Dies 3/8in Drive 21mm Hex

A 20mm die holder for use with M3 to M6 round dies, giving you a compact way to drive smaller dies with tools you may already have in the kit. The 3/8in square drive and 21mm hex make it a practical alternative to a standard die stock when space is limited.

Used for thread cutting, thread chasing and repair work, this holder suits workshop jobs, garage work, light fabrication and general engineering tasks. It is handy when working in tighter areas where a traditional die stock can be awkward to turn, and it allows the use of a ratchet, extension or T-handle for better access. For anyone carrying out regular servicing, small repairs or fitting work, it gives a straightforward way to keep threading jobs moving without needing a larger holder.

The holder is made to take 20mm diameter round dies covering M3 to M6 sizes. Its compact format helps when access is restricted, while the 3/8in square drive fitting pairs with common hand tools already used for maintenance and repair work. The built-in 21mm hex gives another turning option where that suits the job better. For repeated use on smaller threading tasks, it is a useful piece to keep alongside dies and drive tools so the right setup is close to hand when needed.
