Introducing the Carmex Carbide Tiny Tool for small-threading tasks. This MIR-design, full-profile UN 60° threading tool is built for high-precision work on tiny components, supporting UNC, UNF, UNEF, and UNS threads. With a 4.1 mm minimum diameter and 15 mm reach, it fits into tight spaces and across a broad range of machines, delivering reliable results where space is limited.
- Premium carbide for long tool life: Made from high-grade carbide, this tool delivers excellent wear resistance and edge retention, helping you run more cycles between changes and maintain consistent threading performance.
- Full-profile UN 60° geometry for precise threads: The complete UN 60° profile ensures accurate, repeatable thread forms across UNC, UNF, UNEF, and UNS, minimizing rework and improving first-pass quality on small parts.
- Compact size with 15 mm reach for tight workspaces: The 4.1 mm minimum diameter and 15 mm reach let you thread in confined cavities and on miniature components, expanding your application range without sacrificing rigidity.
This tool enables you to produce clean, precise UN threads on small components with confidence. The compact size and extended reach support threading in restricted areas, while the carbide construction minimizes wear and downtime. Compatible with a wide range of machines, it integrates smoothly into existing workflows to enhance throughput and consistent results.
