The Carmex Carbide Tiny Tool is a precision threading bar designed for micro-threading tasks in tight spaces. With a 6 mm minimum shank diameter and a 22 mm reach, this left-handed tool targets small bore workpieces that demand exacting thread profiles. Built for engineers, machinists, and hobbyists alike, it delivers reliable threading performance on stainless steels and other common materials when working with 60° MIL partial profiles. It can thread bore sizes down to 1.2 mm (0.05 in).

Part of Carmex's versatile line of partial-profile threading bars, this tool blends durability and precision. The BXC Grade uses a PVD TiN coating to reduce friction and wear at lower cutting speeds, helping you extract maximum life from the tool when threading challenging stainless steels. The carbide core provides a stable cutting action and consistent thread form across a range of materials.

• TiN-coated carbide for long tool life: TiN coating on the BXC-grade carbide reduces wear and allows reliable threading at lower cutting speeds, extending insert life and minimizing downtime.
• Micro-threading geometry for tiny bores: Partial-profile design with 60° MIL profile compatibility; 6 mm shank and 22 mm reach let you start and finish threads in bores as small as 1.2 mm (0.05 in).
• Left-hand threading capability: Specifically engineered for left-handed threads, enabling clean, consistent results in specialized assemblies and tight spaces.

With this tool, you can complete micro-threading tasks with confidence in tight bores, reduce setup time, and achieve consistent thread quality across stainless steels and related alloys. The combination of a durable carbide core, protective TiN coating, and precise partial-profile geometry helps you improve workflow, cut cycle times, and deliver reliable results on even the smallest components.
