The Carmex Carbide Tiny Tool is a precision threading cutter designed for small-diameter MIL UNJ threads. Built for engineers, machinists, hobbyists, and technicians working on micro components, it delivers consistent, high-accuracy results in tight spaces.

Made from BMK-grade carbide, this compact tool combines toughness and wear resistance to maintain a sharp cutting edge through demanding threading tasks. With a 3.2 mm minimum diameter and a 15 mm reach in a left-hand configuration, it’s ideal for threading small parts and fittings that are difficult to access with larger tools.

• UNJ Threading Precision: Delivers MIL UNJ thread profiles (UNJC, UNJF, UNJEF, UNJS) with tight tolerances to ensure accurate mating and smooth assembly.
• BMK-Grade Carbide Durability: Premium carbide resists wear and chipping, maintaining cutting geometry for longer tool life and fewer replacements.
• Compact Reach for Tight Spaces: 3.2 mm minimum diameter with 15 mm reach and left-hand threading enables clean cuts in small cavities and restricted work areas.

This tool helps you streamline small-threading tasks by enabling precise, consistent cuts in hard-to-reach areas. Its durable carbide and compact geometry reduce downtime, improve part quality, and support reliable performance across a range of machines and applications.
