The Carmex Carbide Tiny Tool is a left-hand, partial-profile threading bar designed for precise internal threads in tight spaces. With a 2.1 mm minimum diameter and 8 mm reach, it’s ideal for small-bore applications where accuracy matters.

This versatile tool fits into a line of partial-profile threading bars and supports two coating grades for different materials. The BXC TiN-coated option reduces friction at lower cutting speeds and performs well on stainless steels (ISO P30-P50 / K25-K40). For highest heat resistance and smooth cutting, the BMK sub-micron grade with triple PVD coating delivers robust, reliable performance across a broad range of materials.

• Coating options for wide material compatibility: BXC TiN-coated for efficient cutting at low speeds on stainless steels, and BMK with a triple PVD coating for maximum heat resistance and consistently smooth cuts across many materials.
• Small-bore threading capability: 2.1 mm minimum diameter and 8 mm reach enable precise threading in tight bores while maintaining solid chip control and thread accuracy.
• Left-hand, 60° partial-profile design: Specifically oriented for left-hand threading with a partial 60° profile, compatible with 55° profiles to fit a range of assemblies and maintain reliable cutting performance.

This tool supports efficient, repeatable internal threading in challenging spaces, helping you complete jobs faster with consistent results. The combination of carbide hardness, protective coatings, and compact geometry reduces dwell time, improves surface finish, and enhances overall reliability across stainless steels and other common materials.
