Carmex Thread Mills Carbide Mini Type - UN (UNC UNF UNEF UNS) - No. 8 x 32 - MT7

The Carmex Thread Mills Carbide Mini Type is a compact, high-performance threading tool designed for precision thread milling in metal parts. Built for engineers and shop floor machinists, it delivers fast, accurate internal and external threads in tight spaces, including deep-hole applications.

• Size and thread forms: No. 8 x 32 thread mill compatible with UNC, UNF, UNEF, and UNS forms for versatile threading in one tool.
• Carbide substrate: MT7 sub-micron carbide with a TiAlN multi-layer coating (ISO K10–K20) for exceptional wear resistance and edge retention.
• Coating and durability: Special triple-coated TiAlN multilayer delivers longer tool life and steadier performance at medium to high cutting speeds.
• Coolant through the flutes: Through-flute coolant directs fluid to the cutting zone, improving chip evacuation and tooling reliability in deep holes.
• Flute design: Spiral flutes provide smooth cutting action and efficient chip removal for clean, accurate threads.
• Number of flutes: 3–5 flutes enable faster material removal and shorter machining times without sacrificing accuracy.
• Machinability across materials: General-purpose threading capable of working with a wide range of materials, including hardened steels up to 45 HRC.
• Deep-hole performance: Short profile and through-coolant design enable threading in deep holes with reduced cutting forces and less risk of breakage.

The MT7 carbide mini thread mill is designed to streamline production by covering multiple thread pitches and both internal and external threads with a single tool. Its combination of high-speed capability, deep-hole through-coolant efficiency, and robust coating makes it a reliable choice for precision threading in demanding assemblies, from aerospace components to precision gear housings. Expect shorter cycle times, reduced tool changes, and consistently accurate threads across a variety of UN thread standards.
