Description
Mill-Thread Insert – BSPT 11 TPI, External & Internal
The 30-11 BSPT MT7 Mill-Thread Insert is designed for producing British Standard Pipe Taper (BSPT) threads using CNC milling machines with helical interpolation. Suitable for both external and internal threading, this insert delivers high-accuracy tapered pipe threads commonly used in pressure-tight sealing applications across gas and fluid systems. With a size 30 body, 16 mm height, and 5.5 mm thickness, it ensures optimal stability and cutting performance for heavy-duty threading operations. Constructed from Carmex’s premium MT7 carbide grade, the insert offers long tool life, superior wear resistance, and clean thread profiles under demanding machining conditions.
This single-sided insert integrates seamlessly with SR series toolholders available in single, twin, and multi-insert configurations with options for internal coolant and carbide shanks. These holders enhance threading precision, improve chip evacuation, and reduce cycle times while providing secure clamping and repeatable accuracy for both low- and high-volume production.
