Description

The Carmex Carbide Tiny Tool is a precision UNJ threading cutter designed for small-diameter workpieces. Built for engineers, machinists, and hobbyists who need tight tolerance threads in confined spaces, this MIL UNJ tool delivers reliable, repeatable results on micro-threads.

Crafted from premium-grade carbide, it offers exceptional durability, wear resistance, and long tool life. Its compact size and compatibility with a wide range of machines make it a versatile choice for small-geometry threading tasks.

  • UNJ threading precision: Delivers accurate UNJ thread forms (MIL) with minimal runout, ensuring clean, reliable threads on small components.
  • Premium carbide durability: High-strength carbide resists wear and maintains cutting edges longer, reducing tool changes and downtime.
  • Compact reach and left-hand geometry: 4.9 mm minimum diameter and 15 mm reach in a left-hand configuration, engineered to access tight spaces across diverse machines.

This tiny threading tool helps you complete micro-threading tasks quickly and with confidence. Its durable carbide construction and precise UNJ geometry translate to fewer reworks, smoother finishes, and reliable performance across multiple setups. The compact form factor expands your machining options in tight joints and assemblies, saving setup time and delivering consistent results on small components.
