Constructed of rugged MT8 carbide with Carmex's exclusive BLU coating, the new FMT thread mill delivers accurate thread geometry and fine surface quality in short cycle times. Unlike conventional taps, the FMT can thread up to the bottom of a blind-hole while delivering the high reliability necessary for complex parts.

FMT's high-speed performance results from the increased number of flutes, which require an extremely heavy-duty carbide grade, as well as advanced coating technology in order to ensure a high degree of performance and
longer tool life.

In a recent test, an FMT thread mill with a 6-flute cutter and internal coolant created a 10mm internal right-hand thread to the bottom of a blind hole in SAE 4340 steel. The cycle time was 1.5 seconds and the tool life was 2,170 threads. In that test, and in any number of other applications, the FMT is emerging as the suitable thread mill for high-production/high-demand applications.
