Carmex Carbide Tiny Tool - Threading - MIR - 60° Partial - BMK Grade - 6mm Minimum Diameter x 22mm Reach

The Carmex Carbide Tiny Tool is a compact internal-threading bar designed for tight spaces and small bore applications. Built for engineers, machinists, buyers, and hobbyists, it delivers precise threading in restricted areas with a 6 mm minimum diameter and a 22 mm reach. This MIR-series tool features a 60° partial-thread profile, enabling accurate cuts in confined bores down to 1.2 mm (0.05 in).

Two advanced coating options are available to boost performance and tool life. The BXC TiN-coated grade is optimized for low cutting speeds and pairs well with a wide range of stainless steels, while the BMK grade uses a sub-micron, triple PVD coating for exceptional heat resistance and smooth cutting across materials. This combination supports reliable results across demanding tasks.

• 60° partial-thread design for tight bores: Designed to access small internal threads with a 6 mm minimum diameter and a 22 mm reach, delivering precise, controlled cuts in space-constrained assemblies.
• Two coating options for durability: BXC TiN coating reduces friction at lower speeds for stainless steels; BMK triple-coated sub-micron grade provides outstanding heat resistance and consistently smooth cutting across materials.
• Wide material compatibility and reliable performance: Works well with a broad range of stainless steels (ISO P30-P50 / K25-K40) and serves as a versatile general-purpose threading tool for many materials.

This tool helps you complete tiny-thread projects with confidence, improving workflow by enabling accurate internal threads in hard-to-reach bores. The combination of precise geometry, proven coating technology, and material versatility supports steady productivity, fewer reworks, and consistent results across a variety of applications.
