M3

When a bolt's threads are damaged or you need to cut fresh external threads on round stock, the right holder makes all the difference between a clean result and a frustrating cross-thread. This Teng Tools unit spans M3 through M12 round dies in a single, lightweight tool that weighs only 127 g.

Two straight handles sit on opposite sides of a central die seat, giving you balanced leverage for smooth, controlled rotation. That symmetry matters: even force on both sides keeps the die tracking straight, which is the single biggest factor in producing accurate, consistent threads. The holder locks the die in place so it cannot rotate inside the seat during the cut.

Metric fasteners from M3 to M12 cover a huge share of the hardware a tradesman encounters daily — small machine screws, mid-range bolts, studs and threaded rod. Having one holder that spans that entire range means fewer tools on the bench and faster changeovers between die sizes. Whether you are rethreading a seized stud on an engine block, cleaning up storm-damaged conduit fittings, or fabricating custom threaded rod in the shop, this tool puts reliable thread-cutting capability in your hands.

The compact size and low weight make it equally at home in a service van, a field kit or a permanent shop drawer. It pairs with any standard round dies in the M3 to M12 range, so you can build your die collection around it over time without replacing the holder.

Organize it alongside your other Teng Tools cutting accessories for a clean, efficient workspace where every tool has a place and every job starts with the right equipment already at hand.
