IN STOCK. Lot of 2 USSR M6 Fluteless Forming Taps

You are bidding on a lot of 2 identical vintage Soviet-era metric fluteless forming taps (also known as roll or thread-rolling/forming taps). Made in the USSR from premium High-Speed Steel (HSS / Russian grade R6M5). True industrial New Old Stock (NOS) items from state reserve storage. Unlike traditional cutting taps, these do not have flutes and do not produce chips. They form internal threads through plastic deformation (cold forming), creating stronger, more precise, and highly wear-resistant M6 threads. Ideal for CNC machining of aluminum, brass, copper, stainless steel, and ductile low-carbon steels. Specifications: - Quantity in lot: 2 pieces (not a standard 1st/2nd step set, both are identical) - Thread Size: M6 (Metric Coarse) - Total Length: 64 mm - Thread Forming Length: 22 mm - Material: Premium Soviet HSS (R6M5) - Design: Fluteless / Forming Type Condition: New old stock (NOS). Excellent vintage condition. Might show minor cosmetic surface darkening/oxidation on the square shank due to decades of storage, but the working threads are intact, never used, and 100% fully functional.
