Description
Mill-Thread Insert – BSPT 11 TPI, External & Internal
The 40-11 BSPT MT7 Mill-Thread Insert is engineered for producing British Standard Pipe Taper (BSPT) threads using CNC milling machines with helical interpolation. Designed for both external and internal threading, this size 40 insert is ideal for creating 11 TPI tapered threads required in high-pressure gas and fluid systems. With a 20 mm height and 6.3 mm thickness, it delivers robust cutting stability and accuracy for large-diameter threading applications. Manufactured from Carmex’s proven MT7 carbide grade, the insert offers excellent wear resistance, thermal stability, and long tool life under demanding machining conditions.
The insert is fully compatible with SR series toolholders, available in single, twin, and multi-insert formats with options for internal coolant and carbide shanks. These holders ensure secure clamping, enhance rigidity, and provide high repeatability making them ideal for high-precision BSPT threading across various production environments.
