Deskripsi
Mill-Thread Insert – UN 8 TPI, Internal
The 40 I 8 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 8 TPI, this insert delivers precise and reliable threading results for mechanical and industrial components using the Unified thread form. With a size 40 profile, 20 mm height, and 6.3 mm thickness, the insert ensures excellent cutting stability, clean thread geometry, and efficient chip evacuation in larger threading operations.
Manufactured from Carmex’s high-performance MT7 carbide grade, the insert provides outstanding wear resistance, consistent machining performance, and extended tool life in demanding environments. 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.
