The Carmex Thread Mills Carbide Mini Type is a compact, high-performance threading solution designed for UNJ threads. Built for machinists who demand versatility and reliability, it delivers precise threads in hard materials and challenging deep-hole applications.
- Thread forms supported: UNJ family including UNJC, UNJF, UNJEF, UNJS, all achievable with a single tool.
- Size and interface: 3/8 x 16 thread mill with MT7 shank for compatibility with standard milling setups.
- Material and coating: Sub-micron MT7 carbide core with Titanium Aluminum Nitride (TiAlN) multi-layer coating (ISO K10–K20) for exceptional wear resistance and heat management; triple coating extends tool life.
- Flute geometry: Spiral flutes with 3–5 cutting edges deliver a smooth cutting action and help shorten machining times.
- Coolant through capability: Through-flutes coolant design provides efficient cooling and debris evacuation, especially in deep-hole threading.
- Cutting performance: Optimized for medium to high cutting speeds, with a short profile that reduces cutting forces and improves stability in demanding jobs.
- Material capability: Capable of threading hardened materials up to 45 HRC, expanding use in tough alloys and toughened steels.
- Versatility: One tool can produce a wide range of thread sizes and pitches and can create both external and internal threads without changing tools.
- Durability: Special triple coating and robust carbide construction deliver longer tool life in demanding production environments.
By using this single, adaptable thread mill, you reduce tooling inventory and cycle times while achieving consistent, accurate threads. The combination of MT7 carbide, TiAlN coating, and through-coolant design enables reliable performance in deep-hole threading and high-speed operations. This makes the Carmex Mini Thread Mill an ideal choice for precision manufacturing, aerospace components, automotive fixtures, and any application that requires durable, versatile internal and external threading with minimal downtime.
