Introducing the Carmex Carbide Mini Thread Mill MT7, a versatile UN-threading tool built for precision work in tight spaces. This carbide mini mill handles UNC, UNF, UNEF, and UNS with a single, durable tool designed for deep holes and high-speed threading.

• Grade & coating: MT7 sub-micron carbide with Titanium Aluminium Nitride (TiAlN) multi-layer coating (ISO K10–K20) for exceptional wear resistance at high speeds
• Thread forms supported: Optimized for UN threads including UNC, UNF, UNEF, and UNS
• Size & compatibility: 7/16" diameter with MT7 shank; designed for 14 TPI thread applications
• Through-coolant & deep-hole threading: Coolant through the flutes provides effective cooling in deep-hole work, aided by spiral flutes for smooth cutting
• Flute count & geometry: Multi-flute design (3–5 flutes) short profile reduces machining time and lowers cutting forces for stability
• Material capability: Capable of machining hardened materials up to 45 HRc, expanding its usable range
• Versatility & practicality: A single tool that can produce a wide range of thread pitches and both external and internal threads, reducing tool changes and setup time

This MT7 carbide mini thread mill delivers reliable, repeatable threads in tight spaces and across a broad material spectrum. Through-coolant flow and a spiral flute geometry minimize heat and chatter, yielding clean, accurate threads and longer tool life in challenging alloys. With the ability to cover multiple thread profiles and both internal and external threads, it reduces setup time, lowers inventory needs, and helps maintain consistent quality in deep-hole applications. A solid choice for precision shops tackling UN-threaded components with demanding standards.
