The Carmex Carbide Tiny Tool - Threading - MIR - 60° Partial - BMK Grade is a compact, precision threading tool designed for micro-bore work. It’s ideal for engineers, machinists, and hobbyists who need reliable 60° threads in tight spaces, with a minimum bore diameter of 1.2 mm (0.05 in) and 6 mm reach, and compatibility with 55° profiles.

• 60° Partial-Profile threading geometry: Designed for micro-bores and tight access, this tool delivers accurate 60° threads with a 6 mm reach in bores as small as 1.2 mm, and it remains compatible with 55° profiles for common standards.
• BXC TiN-coated carbide for low-speed cutting: The PVD TiN coating reduces wear and friction, extending tool life and delivering stable threading performance in stainless steels (ISO P30–P50 / K25–K40) at lower speeds.
• BMK sub-micron grade with triple PVD coating: Advanced coating provides extremely high heat resistance, smooth cutting action, and reliable performance across a wide material range; a strong general‑purpose choice for micro-threading tasks.

Designed to empower precise micro-threading in confined bores, this tool helps you finish projects faster, reduce downtime from tool changes, and achieve consistent thread quality across stainless steels and other materials. The combination of partial-profile geometry and advanced coatings supports reliable performance in demanding shop environments, whether you’re prototyping, repairing small fasteners, or completing production runs.
