The SM301 PCD Thread Milling Tool is a precision thread-milling cutter engineered for high-performance machining of threads in challenging materials. It utilises a PCD (polycrystalline diamond) cutting face (or brazed PCD segments) combined with a robust body/substrate (e.g., carbide or steel) to obtain exceptional wear resistance, low tool-wear, and high dimensional accuracy of thread profiles. Thread milling, rather than tapping, means the tool moves in a helical or circular path around or into the hole, cutting the thread profile. The PCD version is particularly suited for abrasive, non-ferrous, or composite materials where conventional tools wear rapidly. For example, one manufacturer of PCD thread-mills claims “10 × tool life compared to carbide tools” for abrasive materials. The SM301 would typically be specified for a particular thread form (e.g., M, UN, ACME, BSP), pitch, diameter range, and cutting direction (RH/LH). It will often be offered with a “solid PCD” or “braised PCD insert” design, optimized geometry (flutes, chip evacuation), and possibly internal coolant provisions.

PCD Full Face Inserts are cutting tools in which the entire cutting surface is a continuous layer of polycrystalline diamond. Unlike tipped inserts (which have only a PCD edge), full-face designs offer maximum wear resistance, consistent cutting action, and exceptional surface finishes. They are ideal for high-speed machining of non-ferrous metals, aluminum alloys, copper, magnesium, graphite, ceramics, and composite materials where tool life and precision are critical.
