Carmex Thread Mills Solid Carbide - External - UN (UNC UNF UNEF UNS) - 12mm x 20 - MT7

The Carmex Thread Mills Solid Carbide external thread mill is designed for precise, reliable external threading on metal workpieces. Built for machinists who demand clean thread profiles and repeatable results, it supports UNC, UNF, UNEF, and UNS standards with a robust MT7 shank for secure in-machine mounting.

• Material: Solid carbide for high rigidity, wear resistance, and long tool life in demanding threading operations.
• Threading compatibility: External thread milling capable of generating UNC, UNF, UNEF, and UNS threads with consistent tolerance control.
• Size: 12 mm diameter with a 20 mm cutting length, suited for through- and blind-hole applications on compact parts.
• Shank: MT7 Morse taper for secure, precise retention in compatible spindle tooling.
• Flute design: Spiral flutes in a 3–5 flute configuration optimize chip evacuation and deliver a superior surface finish on threaded features.
• Machining efficiency: Multi-flute geometry reduces the number of passes and overall cycle time, increasing productivity on production runs.

This tool excels in production environments and precision workshops where repeatable thread quality and smooth thread surfaces matter. Use it for fastener threads on brackets, housings, adapters, and other components requiring exact external threads. The combination of spiral-flute geometry and carbide rigidity helps minimize vibration and maintain consistent results across multiple parts.
