Carmex Carbide Tiny Tool - Threading - MIL - 60° Partial - BXC Grade - 3.2mm Minimum Diameter x 14mm Reach (Left Hand)

The Carmex Carbide Tiny Tool is a compact, precision threading solution designed for small-diameter work and tight spaces. This left-handed, 60° partial MIL threading tool has a 3.2 mm minimum diameter and a 14 mm reach, making it ideal for threading tasks in confined bores. It’s compatible with 55° thread profiles to help you start and finish cleanly in challenging geometries.

This tool is part of a versatile line offered with two coating grades to match different materials and speeds. The BXC grade uses a PVD TiN coating optimized for low cutting speeds and works well with a wide range of stainless steels (ISO P30-P50 / K25-K40). The BMK grade is a sub-micron option with an advanced PVD triple coating, delivering extremely high heat resistance and smooth cutting for general-purpose use across materials. Minimum bore compatibility remains 1.2 mm (0.05 inch).

• Partial-profile, left‑hand threading for tight bores: Designed for 60° MIL partial geometry and 55° profiles, enabling precise left‑hand threads in confined spaces with minimal tool intrusion.
• BXC TiN-coated option for low-speed cutting: Optimized for low cutting speeds on stainless steels, reducing wear and extending tool life while maintaining consistent thread quality.
• BMK triple-coated option for high heat resistance: Sub-micron grade with advanced PVD coating delivers superior heat tolerance and smooth cutting across a broad range of materials for reliable, all‑purpose performance.

In practice, this tiny carbide tool helps you achieve repeatable, accurate threads in tight bores, with options to match material and cutting conditions. Its compact size, specialized geometry, and durable coatings work together to reduce setup time, lower downtime, and improve surface finish and threading reliability across demanding tiny-part applications.
