Carmex Carbide Tiny Tool is a compact 60° partial-profile threading bar designed for precise internal threads in small bores. It’s ideal for engineers, machinists, and hobbyists who need reliable threading in tight spaces, with a reach that helps you access challenging features. The tool supports a minimum bore diameter of 1.2 mm (0.05 in) and a 4.1 mm minimum diameter with a 17 mm reach, and it’s compatible with partial-profile threading and 55° profiles for versatile applications.

It offers advanced coating options to match your material and process needs. The BXC grade uses a PVD TiN coating optimized for low cutting speeds and stainless steels (ISO P30-P50 / K25-K40), while the BMK grade uses a sub-micron structure with a triple PVD coating for exceptional heat resistance and smooth cutting. This dual-gradable approach provides reliable performance across a broad range of materials.

• 60° Partial-Profile Geometry for Tight Bores: Optimized for small internal threads with a 1.2 mm minimum bore, 4.1 mm minimum diameter, and a 17 mm reach to access confined features while maintaining consistent thread form.
• Coating Options for Versatile Performance: Choose BXC TiN for efficient cutting at lower speeds on stainless steels, or BMK’s triple-coated, high-heat-capacity grade for demanding materials and longer tool life.
• Broad Material Compatibility and Reliability: Designed as a general-purpose threading tool across materials, delivering stable, repeatable results and reducing tool changes in mixed-material workflows.

With its precise geometry, rugged carbide core, and tailored coatings, the Carmex Tiny Tool helps you complete small-bore threading tasks more efficiently, improves consistency across parts, and reduces downtime through longer tool life. Its compact reach and compatibility with common profile standards make it a dependable choice for both professional shops and hands-on projects.
