The Carmex Carbide Tiny Tool – Threading – MIR – 60° Partial is a compact carbide threading bar designed for small-diameter threads in tight bores. It’s built for professionals who need precise, repeatable results in limited space, making it ideal for engineers, machinists, hobbyists, and technicians tackling precision threading tasks.

With a 4.1 mm minimum bore diameter and a 15 mm reach, this tool handles tight workpieces where space is at a premium. It supports partial-profile threading and is compatible with 55° profiles, enabling clean thread formation across common standards. The tool features two high-performance coated grades: BXC TiN for low cutting speeds on stainless steels, and BMK with a sub-micron, triple coating for enhanced heat resistance and smooth cutting across materials.

  • Coating options for versatile performance: BXC TiN provides reliable cutting at low speeds on stainless steels (ISO P30-P50 / K25-K40) while BMK’s sub-micron, triple PVD coating delivers high heat resistance and consistently smooth cuts across a broad material range.
  • Compact, precise threading geometry: Partial-profile 60° threading with a 4.1 mm minimum bore diameter and 15 mm reach lets you access restricted bores and small workpieces, while maintaining compatibility with 55° profiles for diverse applications.
  • Durable carbide for long tool life: Built on a K20-grade carbide core, this tool offers dependable durability and consistent performance in demanding materials, supporting reliable results across ISO ranges.

When you choose the Carmex Tiny Tool, you gain a dependable threading solution that helps you complete tight-bore projects faster and with fewer reworks. The carbide core, combined with advanced PVD coatings, provides durable performance across stainless steels and other materials, while the compact geometry reduces tool changes and improves access in crowded setups. This leads to smoother workflows, improved part quality, and greater overall productivity in fabrication, maintenance, or repair tasks.
