Left Hand Thread HSS Die Set - M3 To M30 Metric Left Hand Thread Cutter - USSR/Germany

Need to cut left hand threads?

This die set covers you from tiny M3 all the way up to M30.

These are HSS (high-speed steel) dies, so they're tough and hold an edge.

The thread type is metric standard (M Regelgewinde), and the rotation is left-hand (Links).

They're marked as USSR/UdSSR but made in Germany - interesting history there.

Includes a die holder (Bohrfutterschlüssel) so you're ready to work.

Whether you're restoring old machinery, working on custom fasteners, or need left hand threads for a specific project, this set has you covered.

Brand is UdSSR/USSR, manufacturer number not applicable.

These are new old stock, likely from the Cold War era but unused.

A rare find for machinists and tool collectors.

Cut those reverse threads with precision!
