The Carmex Carbide Tiny Tool is a TNX-grade, partial-profile threading bar built for 55° MIL internal threads in tight bores. Its compact 6 mm diameter and 22 mm reach (Left Hand) make it ideal for hard-to-access locations, with the ability to thread bores as small as 1.2 mm (0.05 in). This tool is designed for engineers, machinists, and hobbyists who need reliable internal threading in confined spaces.

• 55° partial-profile threading design: Delivers precise internal threads in small bores with minimal overhang and reduced tool deflection, enabling clean, accurate fits in restricted cavities.
• Coatings tailored for versatility: Choose BXC TiN for low-speed cutting in stainless steels (ISO P30-P50 / K25-K40) to reduce wear, or BMK with a sub-micron, triple PVD coating for outstanding heat resistance and smooth cutting across a wide material range.
• Compact reach with left-hand configuration: A 22 mm reach in a 6 mm tool footprint and a left-hand orientation expand accessibility to deep or awkward threads, improving setup flexibility and reducing repositioning.

This tiny threading tool combines robust carbide durability with coating versatility to deliver consistent thread quality, lower maintenance, and broad material compatibility. Its thoughtful geometry and reach help you complete tight-bores threading tasks more efficiently, with confidence in repeatable results across demanding applications.
