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-performance threading tool designed for machinists who need fast, precise internal and external threads in deep holes. With a 5/16 x 18 UNC size and an MT7 shank, it delivers reliable performance across materials at medium to high cutting speeds.

• Thread forms and access: Supports UNC, UNF, UNEF, and UNS thread forms and can machine both internal and external threads with the same tool.
• Carbide MT7 with TiAlN coating: Sub-Micron MT7 carbide with a multi-layer TiAlN coating (ISO K10–K20) for high hardness, heat resistance, and extended life.
• Through-coolant for deep holes: Coolant through the flutes provides efficient cooling and chip evacuation in deep-hole pockets, improving surface finish and tool life.
• Flute design and pitch: Spiral flutes deliver smooth cutting action; 3–5 flutes reduce machining time and enhance chip control for better performance.
• Depth capability: Optimized for deep-hole threading, enabling accurate threads in challenging geometries without frequent tool changes.
• Material versatility: General-purpose threading capable of machining hardened materials up to 45 HRC and a wide range of other materials.
• Reliability and lifecycle: Short profile minimizes cutting forces and chatter, contributing to fewer tool failures and longer overall tool life.
• Size and compatibility: 5/16 x 18 thread size with MT7 shank compatibility for a broad set of CNC machines and setups.

This tool is ideal for production environments where quick setup, versatility, and durable threading performance matter. Use it to replace multiple dedicated taps and to streamline threads in engines, manifolds, hydraulic components, molds, and other assemblies that require consistent, high-quality threads. The combination of through-coolant, multi-flute geometry, and advanced coating makes it a dependable choice for high-speed threading across a range of materials, including hardened steels.
