Description
Mill-Thread Insert – UN 5 TPI, Internal
The 30 I 5 UN MT7 Mill-Thread Insert is specifically engineered for internal threading of Unified National (UN) profiles on CNC milling machines using helical interpolation. Designed to cut at 5 TPI, this insert delivers precise and reliable threading results for large-pitch Unified threads commonly used in industrial and mechanical assemblies. With a size 30 profile, 16 mm height, and 5.5 mm thickness, the insert ensures cutting stability, clean thread geometry, and optimal chip evacuation in heavy-duty operations.
Manufactured from Carmex’s high-performance MT7 carbide grade, the insert provides excellent wear resistance, consistent performance, and extended tool life across production runs. For maximum threading efficiency, this insert is compatible with Carmex’s comprehensive range of SR series toolholders available in single, twin, and multi-insert formats, with options for carbide shanks and internal coolant supply. These holders are designed to match insert sizes and ensure secure clamping and high-performance machining.
