The Carmex Carbide Tiny Tool is a partial-profile threading bar designed for precise internal threading with a 55° profile. Its compact 6 mm diameter and 15 mm reach let you cut clean, accurate threads in tight bores, including those as small as 1.2 mm (0.05 in). Compatible with 55° thread profiles, this tool is ideal for engineers, machinists, and technicians working in constrained spaces where precision matters.

Designed for versatile performance, the Carmex Tiny Tool is offered in two TNX-grade coatings to match your application. The BXC grade features a PVD TiN coating optimized for low cutting speeds and broad stainless steel compatibility (ISO P30-P50 / K25-K40). The BMK grade uses a sub-micron structure with a triple PVD coating to deliver exceptional heat resistance and a smooth cutting action, suitable for demanding materials and long service life. Both options are built to work across a wide range of materials while maintaining consistent results.

• 55° Partial-threading design: Precisely forms internal threads with a partial-profile geometry that fits into tight bores while delivering consistent thread form.
• Coated for durability and performance: Choose BXC TiN for efficient low-speed cutting in stainless steels or BMK for maximum heat resistance and smooth cutting under tougher conditions.
• Compact, accessible geometry: 6 mm tool diameter with 15 mm reach enables threading in restricted spaces and small bore diameters down to 1.2 mm.

This tool helps you finish internal threads faster with reliable results, reducing rework and downtime. The two coating options provide flexibility to optimize cutting speed, tool life, and surface finish across common stainless steels and other materials, making it a dependable choice for setups that demand precision and repeatable performance.
