Carmex Carbide Tiny Tool is a compact threading solution designed for precision inside small bores. The 60° partial-profile tip and a 4.1 mm minimum diameter with a 15 mm reach let you form threads in tight spaces and short components with consistent results. It’s built to work with standard 55° thread profiles, making it a practical choice for a wide range of internal-threading tasks.

This BMK Grade variant uses a sub-micron carbide with advanced PVD triple coating to deliver high heat resistance and smooth cutting across materials, including stainless steels. With a minimum bore capability of 1.2 mm (0.05 in), this tool is suited for general-purpose threading in small features where reliability matters.

• Compact form factor for tight bores: 4.1 mm minimum diameter and 15 mm reach let you thread inside small cylindrical features and short housings without repositioning the workpiece.
• BMK Grade carbide with advanced PVD triple coating: Sub-micron grade delivering extremely high heat resistance and smooth cutting, providing reliable performance across materials (ISO K10-K20) and general-purpose use.
• 60° partial-profile geometry for compatibility with 55° threads: Form precise 60° partial threads while remaining compatible with common 55° profiles, enabling versatile use across many internal-threading jobs.

By combining a small, high-precision form with BMK-grade coating and 60° partial-profile geometry, this tool helps you complete tight internal threaded features faster, reduces tool changes, and delivers consistent results across stainless steels and other materials. The high heat resistance and smooth cutting translate to longer tool life and fewer interruptions in production, improving workflow and overall performance.
