Carmex Carbide Tiny Tool – Threading – MIR – 60° Partial – TNX Grade – 5.1 mm Minimum Diameter x 22 mm Reach is a precision micro threading tool designed for internal threads in tight spaces. Built as a compact carbide bar, it delivers reliable threading performance in restricted bores for engineers, machinists, technicians, and hobbyists who work in compact machine setups.

This 60° partial threading tool is engineered for versatility: it supports a 60° MIR partial profile and is compatible with 55° profiles, expanding its use across a wide range of internal-thread tasks. It covers micro-bore threading down to 1.2 mm, with a 5.1 mm diameter and 22 mm reach. Choose from coatings that match material and speed needs: BXC for low cutting speeds on stainless steels (ISO P30-P50 / K25-K40) or BMK with a sub-micron, triple PVD coating for high heat resistance and smooth cutting (ISO K10-K20).

• Ultra-compact micro-threading capability: Access small internal threads and tight bores (down to 1.2 mm) with a 5.1 mm diameter and 22 mm reach, enabling precise work in confined spaces.
• Coating options for diverse materials: BXC TiN coating supports low cutting speeds on stainless steels, while BMK’s sub-micron triple coating provides high heat resistance and smooth cutting for broader material ranges, helping you match performance to the job.
• 60° MIR partial profile with 55° compatibility: Designed for 60° MIR partial threading and compatible with 55° profiles, expanding applicability across common internal-thread tasks without tool changes.

This micro-threading tool helps you achieve consistent internal-thread quality in micro-bores, reduces setup time and tool changes, and supports reliable performance across stainless steels and other materials. The compact design and coating options enable efficient workflows, improve surface finish and thread accuracy, and extend tool life for demanding applications.
