Mill-Thread Insert – WHIT 11 TPI, External & Internal

The 30-11 W MT7 Mill-Thread Insert is specifically engineered for producing British Standard Whitworth (BSW/BSF/BSP) threads using CNC milling with helical interpolation. Designed for both external and internal threading, this insert conforms to the 55° Whitworth profile and is ideal for precision thread milling in mechanical, fastening, and hydraulic applications. With an insert size of 30, a height of 16 mm, and a thickness of 5.5 mm, it delivers solid cutting stability and high accuracy for medium to large thread sizes. Manufactured from Carmex’s proven MT7 carbide grade, this single-edge insert provides excellent tool life, wear resistance, and thread consistency under high-load and extended production conditions.

As part of the Carmex Mill-Thread system, this insert ensures fast and reliable threading performance across a wide range of setups. It is also fully compatible with SR series toolholders available in single, twin, and multi-insert formats, featuring internal coolant options and reinforced carbide shanks. These holders ensure secure clamping, maximum rigidity, and high repeatability, making them ideal for demanding thread milling applications.
