M12 Left-Hand Threading Die

This HSS die cuts M12 x 1.75 left-hand external threads on rods or bars. It suits maintenance technicians and machinists who need to create or repair reverse-threaded fasteners in industrial settings. The 38 mm round body fits standard die stocks and holders.

Simple to fit in a compatible die stock

The 38 mm diameter and 14.5 mm thickness match common holder dimensions for secure clamping. Alignment must be kept square to the workpiece to avoid tapered or damaged threads. Cutting fluid is essential to reduce wear and achieve a clean finish on the material.

For creating or repairing M12 left-hand threads

It suits engineers and mechanics working with reverse-threaded assemblies. Buyers needing right-hand threads or different diameters should select the matching die for their specific pitch and size requirements.

Questions about this item

How can I verify the M12 x 1.75 left-hand die is cutting correctly after setup?

Run the die onto a clean M12 rod; the freshly cut threads should accept a matching M12 x 1.75 left-hand nut with smooth engagement and no binding.

What comes in the package and what must I supply separately?

The box contains one 38 mm diameter HSS threading die; you must provide a compatible die stock or holder, cutting fluid and the M12 workpiece.

Which specification should I match when selecting this die?

Choose this version only if you need a 38 mm outside diameter, 14.5 mm thick die for M12 x 1.75 left-hand metric threads.
