Die Holder 50mm 1/2in Square Drive 25mm Hex for M16-M20 Dies

A practical die holder for using 50mm round threading dies with common 1/2in square drive tools. Built to suit M16 to M20 die sizes, it gives you a straightforward way to cut or chase threads when a standard die stock is less convenient.

Used for thread cutting, thread repair and chasing damaged threads in workshop, garage and general engineering jobs. It suits buyers working on vehicle maintenance, repair work, fabrication and general servicing where larger threads come up, especially when access is tighter or you want to use tools already in your box rather than a separate holder.

The holder accepts 50mm diameter dies and can be paired with a ratchet, extension or T-handle through its 1/2in square drive, giving more flexibility depending on the space available and the way you prefer to turn the die. The 25mm hex form adds another familiar drive option for matching with suitable hand tools. For awkward spots, longer reach setups or steadier control while starting and chasing threads, that makes it a useful option for regular maintenance and repair work.
