The Carmex Carbide Tiny Tool - Threading - MIL - UN (UNC, UNF, UNEF, UNS) - K20 Grade is a precision threading cutter designed for producing small, accurate UN 60° threads on tight-feature parts. Built for engineers, machinists, hobbyists, and production environments, it delivers clean, repeatable results in compact workpieces thanks to its full-profile UN 60° geometry and MIL specification. Crafted from premium K20 carbide, this tool offers excellent wear resistance and long life, making it a reliable choice for demanding small-diameter threading tasks. Its compact form (4.1 mm minimum diameter x 15 mm reach) enables threading in spaces where larger tools can’t reach.

• Ultra-compact threading reach: With a 4.1 mm minimum diameter and 15 mm reach, this tool fits into tight bores and small parts, enabling precise threads in confined spaces.
• Full-profile UN 60° geometry for UNC/UNF/UNEF/UNS: Engineered to create true, consistent threads across common UN forms, improving fit, assembly reliability, and repeatable results.
• Premium K20 carbide for long life: Durable cutting edges provide excellent wear resistance, reducing tool changes and maintaining sharpness for extended production runs.

This tool helps streamline small-diameter threading tasks, delivering reliable, repeatable results with less downtime. Its robust carbide construction handles demanding materials, while the compact reach supports efficient setup and faster cycle times, enabling you to finish tight-tolerance components with confidence.
