The Carmex Carbide Tiny Tool is a compact threading bar designed for partial-profile threading in tight spaces. It’s ideal for engineers, machinists, and hobbyists who need precise, repeatable threads in small bore workpieces, including stainless steels.

This versatile tool supports a minimum bore diameter of 1.2 mm (0.05 in) and a reach of 22 mm, and it is compatible with 55° profiles, making it suitable for demanding small-bore threading tasks.

• Coatings for versatile performance: BXC TiN-coated grade enables reliable cutting at low speeds and pairs well with a wide range of stainless steels (ISO P30-P50 / K25-K40).
• High-heat, long-life BMK grade: Sub-micron BMK with advanced PVD triple coating delivers extremely high heat resistance and smooth cutting across demanding materials (ISO K10-K20).
• Compact geometry for tight bores: 8 mm minimum diameter and 22 mm reach, compatible with 55° profiles, enable precise threading in small bore geometries down to 1.2 mm.

When you choose this tool, you get reliable, repeatable threading performance across a wide material range, with longer tool life thanks to advanced coatings and optimized cutting speeds. The compact design improves access in confined spaces and helps streamline setups, so you can complete projects with consistent quality and fewer interruptions.
