Carmex Thread Mills Carbide Mini Type - UN (UNC UNF UNEF UNS) - 5/16 x 18 - MT7

The Carmex Thread Mills Carbide Mini Type is a compact, high-precision threading tool designed for versatile UN thread forms (UNC, UNF, UNEF, UNS). Sized at 5/16 x 18 with an MT7 shank, it excels in deep-hole threading and high-speed production without sacrificing accuracy.

• Material & coating: MT7 sub-micron carbide with a TiAlN multi-layer coating (ISO K10–K20) for exceptional wear resistance at medium to high cutting speeds.
• Thread compatibility: Supports UN family threads including UNC, UNF, UNEF, and UNS, enabling a single tool to cover multiple pitch options.
• Hole-depth capability: Through-coolant enabled flute design and spiral flutes deliver smooth cutting and effective cooling in deep holes.
• Flute configuration: Multi-flute geometry (3–5 flutes) reduces machining time and distributes cutting forces for stable, precise milling.
• Internal & external threads: The same tool can produce both external and internal threads, expanding versatility without swapping tools.
• Speed & performance: Engineered for medium to high cutting speeds with short profile to minimize cutting forces and chatter.
• Durability: Special triple coating and robust carbide construction extend tool life, even when machining hardened materials up to 45 HRC.

This tool is ideal for shops performing threaded features in tight tolerances and in hardened materials. It enables quick, reliable threading in deep holes, reduces the risk of broken taps, and supports a wide range of thread pitches with a single, durable carbide mill. Use cases include precision insert cavities, engine components, and mold bases where both internal and external threads are required, all while maintaining efficient cycle times and consistent results.
