The Carmex Carbide Tiny Tool is a compact left-hand threading tool designed to install precise internal threads in tight spaces. With a 5.1 mm minimum diameter and 15 mm reach, it’s built to handle MIL-grade 60° partial-profile workpieces and is compatible with 55° profile geometries, making it versatile for small-bore applications and a range of stainless steels.

Engineered for reliability, the BMK grade uses a sub-micron carbide structure with an advanced PVD triple coating, delivering extremely high heat resistance and a smooth cutting action for consistent thread quality across demanding materials.

• Compact, left-handed 5.1 mm tool with 15 mm reach: Access tight bores and maintain consistent threading depth in small cavities, enabling precise internal threads in restricted spaces.
• 60° partial-profile design with cross-compatibility: Optimized for MIL 60° partial profiles while offering flexibility with 55° profiles to suit a variety of part geometries and reduce tool changes.
• BMK-grade carbide with triple PVD coating: Provides excellent wear resistance and smooth cutting at elevated temperatures, helping extend tool life and maintain surface finish on stainless steels.

This tool delivers dependable performance for engineers, machinists, and hobbyists alike—helping you complete accurate internal threads quickly, reduce downtime from wear, and achieve reliable results across a broad range of materials.
