Carmex Carbide Tiny Tool - Threading - MIL - 60° Partial - BMK Grade - 2.1mm Minimum Diameter x 8mm Reach (Left Hand) is a compact, precision threading tool designed for small-diameter work where space is limited. This partial-profile threading bar is compatible with 55° profiles and is built to deliver reliable, repeatable threads in tight bores. It’s a versatile solution for engineers, machinists, hobbyists, and technicians working with a range of materials.

• BMK-grade PVD coating for heat and durability: The BMK variant uses a sub-micron PVD triple coating to provide extremely high heat resistance and smooth, controlled cutting across a broad material range, helping you achieve consistent thread quality.
• BXC TiN coating option for low-speed threading and stainless steels: This TiN-coated grade enhances performance at lower cutting speeds and improves wear resistance when working with stainless steels, extending tool life in demanding applications.
• Compact 60° MIL threading geometry with precise reach: Designed for tight spaces, it features a 2.1 mm minimum diameter and an 8 mm reach (left hand), with minimum bores down to 1.2 mm, and compatibility with 55° profiles for flexible, reliable threading in constrained parts.

Together, these features deliver reliable, high-quality threads in small bores with minimal setup effort. The tool’s compact form and tailored coatings help reduce downtime and wear, while the left-handed, partial-profile geometry expands where and how you can apply threading work. Whether you’re tackling fine-thread work in tight housings or preparing precision components, this Carmex Tiny Tool provides predictable performance and confident results across a wide range of materials.
