Mill-Thread Insert – NPT 11.5 TPI, External & Internal

The 30-11.5 NPT MT7 Mill-Thread Insert from Carmex is designed for producing precise NPT (National Pipe Taper) threads using helical interpolation on CNC milling machines. Suitable for both external and internal applications, this insert supports 11.5 TPI conical pipe threads in accordance with American thread standards. Its robust 30-size profile, with a 16 mm height and 5.5 mm thickness, delivers stability and dimensional accuracy even under aggressive cutting conditions in challenging materials. Constructed from Carmex’s advanced MT7 carbide grade, this single-sided insert offers superior wear resistance, prolonged tool life, and a consistent finish across varied production cycles.

For optimal performance, the insert is fully compatible with SR series toolholders available in single, twin, and multi-insert formats with internal coolant and reinforced carbide shank options. These holders are designed to maximize clamping rigidity, reduce cycle times, and enhance thread accuracy, making them ideal for both small-batch and high-volume manufacturing environments.
