The Carmex Carbide Tiny Tool is a left-hand, 55° partial-profile threading bar designed for precise internal threads in tight spaces. With a compact 3.2 mm tool diameter and a 15 mm reach, it’s ideal for miniature components and hard-to-access bores.

Part of a versatile line of partial-profile threading bars, this tool supports 55° profiles and bores down to 1.2 mm (0.05 in). Built in K20 grade carbide, it aligns with coating options in the family, including BXC TiN-coated grades for low cutting speeds and BMK triple-coated grades for high heat resistance and smooth cutting, delivering reliable performance across stainless steels and a wide range of general materials.

  • 55° partial-profile threading compatibility: Enables precise internal threads in tight spaces by matching the 55° profile and the partial-profile geometry.
  • Compact left-hand design with 3.2 mm diameter and 15 mm reach: Access narrow bores and recessed areas while maintaining consistent thread quality in left-handed operations.
  • K20 carbide with dual coating options: BXC TiN-coated grades for low cutting speeds and BMK triple-coated grades for high heat resistance and smooth cutting, expanding material suitability across stainless steels and general-purpose work.

With its precise geometry, compact form, and coating versatility, this tool helps you complete micro-threading tasks faster and more consistently. The combination of small bore capability, left-hand threading, and robust K20 carbide performance supports efficient workflows, reduced downtime, and repeatable results across a range of challenging applications.
