The Carmex Carbide Tiny Tool is a compact, left‑hand threading bar made in K20 grade carbide for precise internal threads in small bores. It features a 60° partial-profile geometry and a reach of 22 mm with an 8 mm minimum bore diameter (1.2 mm / 0.05 in). Compatible with 55° profiles, this tool is suitable for a wide range of stainless steels and other materials, making it a versatile choice for engineers, machinists, and hobbyists alike.

• TiN-coated BXC grade for smooth, controlled cutting: Optimized for low cutting speeds to reduce wear and maintain consistent thread quality on stainless steels (ISO P30-P50 / K25-K40).
• BMK grade with triple PVD coating for high heat resistance: Sub-micron carbide delivers exceptional heat tolerance and smooth cutting for demanding materials and higher-speed operations.
• Compact 60° partial-profile geometry with precise reach: 8 mm minimum diameter, 22 mm reach, left-hand threading, and compatibility with 55° profiles for tight, accurate internal threads in restricted spaces.

This tool is designed to streamline your threading work by delivering reliable, repeatable results in small bores. The dual coating options provide flexibility across materials, while the compact form and left-handed design help you work efficiently in confined areas, reducing downtime and improving overall workflow.
