Round Die Holder 25mm M3-M12 3/8in Square Drive 21mm Hex

A round die holder for 25mm threading dies, used for cutting new threads or cleaning up damaged ones on bolts, studs and threaded bar. The holder suits dies from M3 to M12 and gives you a straightforward way to drive them with common hand tools rather than relying on a traditional die stock.

Used for garage work, workshop repairs and general maintenance, it helps when threading jobs need better access or a steadier turning action. Mechanics, engineers and DIY users can use it for thread repair, recutting worn threads and cutting fresh threads where space is limited or where a ratchet setup is easier to control. It is also useful when working in tighter spots where a standard holder can feel awkward.

The holder takes 25mm diameter round dies and covers a practical M3 to M12 size range for everyday threading work. A 3/8in square drive allows use with a ratchet, extension or T-handle, which can help with reach and handling depending on the job. There is also a 21mm hex on the body, giving you the option of turning it with a spanner when that suits the setup better. The dual drive arrangement makes it easier to adapt to different access positions and helps avoid switching between tools more than necessary during regular thread repair work.
