Carmex Carbide Tiny Tool - Threading - MIL - 60° Partial - BMK Grade - 6mm Minimum Diameter x 22mm Reach (Left Hand)

The Carmex Carbide Tiny Tool is a 60° MIL partial-profile threading bar designed for small-diameter internal threads in tight spaces. With a 6 mm minimum diameter and a 22 mm reach, it’s built for engineers, machinists, and hobbyists who work in confined assemblies. The tool features a left-hand threading orientation and is compatible with 55° profiles to maximize versatility across mixed-thread applications.

Designed for small-bore work, this tool handles bores down to 1.2 mm (0.05 in) and delivers reliable, controlled cuts across a wide range of materials. It’s offered in coating grades tailored for different speeds and materials: BMK grade provides extremely high heat resistance and smooth cutting, while BXC TiN coating supports low cutting speeds and strong performance with stainless steels (ISO P30-P50 / K25-K40).

• BMK and BXC coating options: BMK’s sub-micron grade with triple PVD coating delivers maximum heat resistance and smooth cutting across many materials, while BXC TiN coating is optimized for low cutting speeds and stainless steels, broadening material compatibility.
• Small-bore capability with long reach: 6 mm minimum diameter and 22 mm reach enable precise internal threading in tight cavities, reducing the need for multiple tools and simplifying setups.
• 60° MIL partial-profile geometry with 55° compatibility and left-hand threading: Partial-profile design supports 60° MIL threads while remaining compatible with 55° profiles, and the left-hand orientation adds flexibility for diverse assemblies.

Together, these features translate to reliable, efficient threading performance in challenging spaces. The carbide construction promotes long tool life and consistent results, while the specialized coatings reduce wear and heat buildup. The compact size and reach streamline workflows, minimize tool changes, and help you complete assemblies faster with confidence.
