Carmex Thread Mills Carbide Mini Type MT7 is a compact, high-performance threading tool designed for both internal and external threads. With No. 1 and No. 2 sizes and a 64 mm length, it excels in deep-hole work and tight-spaced assemblies, delivering precise threads in a wide range of Unified thread forms (UNC, UNF, UNEF, UNS).

• Thread forms supported: UNC, UNF, UNEF, UNS with No. 1 and No. 2 sizes for versatile threading in a single tool
• Material & coating: Carbide MT7 with sub-micron grain and a TiAlN multi-layer coating (ISO K10–K20) for outstanding wear resistance
• Flute design: Spiral flutes provide smooth cutting action and efficient chip evacuation
• Coolant through: Through-flutes enable effective coolant delivery in deep-hole applications for better heat management
• Cutting edges: Optimized for medium to high cutting speeds to shorten cycle times
• Threading capability: One tool can produce a wide range of pitches and both external and internal threads
• Hole accessibility: Short profile reduces cutting forces and improves stability in challenging geometries
• Material hardness: Capable of machining hardened materials up to 45 HRc
• Durability: Triple coating and specialized geometry extend tool life, reducing tool changes and downtime
• Reliability: Design minimizes the risk of broken taps, even in demanding high-speed threading tasks

In practical terms, this MT7 mini thread mill helps shops speed up production by eliminating the need for multiple dedicated taps or threading tools. Its through-coolant capability, short profile, and multi-flute geometry enable reliable deep-hole threading with tight tolerances and clean surface finish. Whether you’re setting up for automotive components, hydraulic fittings, or precision-machined parts, this tool offers consistent performance, versatile threading options, and longer life per tool, making it a dependable workhorse for high-speed, high-precision threading tasks.
