Description

The Carmex Carbide Tiny Tool is a precision threading cutter designed for small-diameter threads in tight spaces. Its MIL trapezoidal thread design delivers high-accuracy results on tiny parts, making it ideal for engineers, technicians, and hobbyists who require repeatable, clean threads.

Constructed from premium TNX-grade carbide for outstanding durability and wear resistance, this tool features a 6.9 mm minimum diameter and a 25 mm reach. It is suitable for left-hand threading and is compatible with a wide range of machines and systems, giving you versatile performance across many applications.

  • Compact 6.9 mm minimum diameter: Enables precise threading on small parts in tight spaces, reducing setup time and error.
  • 25 mm reach for access in recessed areas: Lets you thread features that are hard to reach without repositioning the setup.
  • Premium TNX-grade carbide with MIL trapez design: Delivers durable, wear-resistant performance with consistent, high-accuracy thread quality across demanding applications.

In practice, the Carmex Tiny Tool reduces guesswork in small-thread projects. The tight tolerances of the trapezoidal MIL thread deliver smooth engagement and repeatable performance, even on delicate parts. Its carbide composition stands up to wear, extending tool life and cutting cycles, while broad machine compatibility means you can integrate it into existing setups without retooling. For left-hand threading jobs, this tool provides a dependable option that consistently delivers clean, accurate results across demanding applications.
