Carmex Carbide Tiny Tools – Small Threading ISO Tool (MIL) is a precision cutting tool designed for micro-threading tasks. Crafted from premium carbide, it delivers the strength and wear resistance needed for reliable, accurate threads in small-diameter parts.

Ideal for engineers, machinists, hobbyists, and technicians who work in tight spaces, this compact tool handles ISO threading standards with MIL/Metric compatibility, making it a versatile choice for a range of machines and setups.

  • Ultra-compact threading for small parts: 4.9 mm minimum diameter and 15 mm reach (left-hand) allow precise internal and external threads on tiny components, even in restricted work areas.
  • Premium carbide for long tool life: carbide construction provides exceptional wear resistance and stiffness, helping you sustain accurate threads through many cycles and tough materials.
  • ISO threading with MIL/Metric compatibility: designed to work with standard ISO thread profiles and MIL/Metric systems, enabling reliable, repeatable results across a wide range of machines and applications.

With its compact form and robust carbide composition, the Carmex Tiny Tool removes guesswork from micro-threading projects. You gain consistent thread quality on small parts, reduced downtime from tool changes, and the confidence that your tooling will perform reliably across different machines and materials. This tool is a practical, durable choice for precision work in electronics, medical devices, aerospace components, or any project requiring accurate small-threading results.
