Carmex Thread Mills Solid Carbide External, Metric 12 mm x 1 with MT7 shank, is a precision external thread milling tool designed for CNC machinists who demand accurate threads and a superior surface finish. Built for metalworking applications, this tool combines spiral flutes with a multi-flute design to deliver both quality and efficiency on demanding production runs.

• Diameter: 12 mm
• Thread pitch: 1 mm
• Shank: MT7 Morse taper
• Material: Solid carbide
• Flute design: Spiral flutes for enhanced surface finish
• Flute count: 3–5 flutes for efficient chip evacuation and rigidity
• Application: External thread milling

The spiral flutes and multi-flute configuration work together to minimize cutting time while maintaining tight dimensional control, resulting in clean, consistent external threads. The solid carbide construction delivers the rigidity and wear resistance needed for precision threading in a range of metals, while the MT7 shank ensures compatibility with standard high-speed milling setups. This tool is well-suited for through-holes, sleeves, and external threading tasks in automotive, aerospace, and general precision engineering projects, helping you achieve reliable thread forms and smooth finishes in fewer passes.
