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

The Carmex Thread Mills Carbide Mini Type MT7 is a compact, high‑performance threading tool built for precision work across a wide range of materials. Designed for professionals who need reliable internal and external threads in tight spaces, it excels at high-speed machining with consistently accurate results.

• Tool material: Carbide MT7 substrate with sub‑micron cutting edges for precise thread profiles.
• Coating system: Titanium Aluminium Nitride (TiAlN) multi‑layer coating, triple‑layer design for enhanced wear resistance and longer tool life (ISO K10–K20).
• Thread forms supported: UNC, UNF, UNEF, UNS; capable of producing No. 8 x 32 threads with internal or external threading in a single operation.
• Flute design: Spiral flutes provide smooth cutting action and efficient chip evacuation; through‑coolant channels improve cooling for deep holes.
• Profile and efficiency: Short tool profile reduces cutting forces; multi‑flute configuration (3–5 flutes) shortens machining time and stabilizes every thread pass.
• Speed and materials: Optimized for medium to high cutting speeds and versatile enough for general materials; capable of machining hardened materials up to 45 HRc.
• Depth capability: Coolant through the flutes enhances lubrication and heat removal, enabling effective threading in deeper bores.
• Versatility: One tool can produce a wide range of thread pitches and sizes, and can create both external and internal threads with the same cutter.

Benefits: The MT7 mini thread mill delivers fast, reliable threading with reduced cycle times thanks to its short profile and multi‑flute geometry. The triple TiAlN coating and carbide substrate maximize tool life under demanding speeds, while coolant‑through flutes minimize heat and chip buildup in deep holes. This makes it ideal for precision manufacturers in aerospace, automotive, moldmaking, and general engineering who need durable, versatile threading tools that can handle hardened materials without compromising thread quality.
