Carmex Carbide Tiny Tool - Threading - MIR - 55° Partial - TNX Grade - 6mm Minimum Diameter x 22mm Reach is a compact carbide threading tool designed for internal threads in small bores. The 55° partial-profile tip focuses cutting where it matters, delivering clean, accurate threads in a range of materials. It’s ideal for engineers, machinists, and technicians who need precise internal threading in tight spaces without resorting to multiple tools.

Built on a robust TNX-grade carbide body, this tiny threading tool pairs with specialized coatings to optimize performance. The product line includes coatings that suit different applications: BXC TiN coating for low cutting speeds and good performance with stainless steels (ISO P30-P50 / K25-K40), and BMK sub-micron coating with advanced PVD triple layers for high heat resistance and smooth cutting. The tool accommodates a minimum bore diameter of 1.2 mm (0.05 in) and offers a 22 mm reach from a 6 mm shank, enabling access to deep or hard-to-reach internal threads.

• 55° partial-profile threading design: Enables precise internal threads in tight bores while maintaining reliable engagement and predictable results.
• Coated for durability and versatility: BXC TiN coating supports low-speed cutting on stainless steels; BMK triple coating provides high heat resistance for demanding materials, helping extend tool life.
• Compact reach with ample access: 6 mm minimum diameter and 22 mm reach allow threading in small cavities, with a minimum bore diameter of 1.2 mm supporting a wide range of internal thread sizes.

This tool helps you complete precise internal threads with confidence, improving workflow efficiency, reducing rework, and delivering consistent results across materials. Its compact geometry, strong carbide core, and targeted coatings make it a reliable choice for maintenance, repair, and production environments where tight bore threading is required.
