The Carmex Carbide Tiny Tool is a compact internal-threading solution designed for small bores and tight spaces. Its 60° MIR partial threading geometry is compatible with 55° thread profiles, enabling precise, repeatable threads in hard-to-reach areas. With a minimum bore diameter of 1.2 mm (0.05 in) and a reach of 15 mm, this tool is ideal for compact assemblies and precision repair work.

Manufactured with carbide and backed by advanced coatings, this tool line delivers durability and smooth cutting across a wide range of materials. The BMK Grade offers sub-micron carbide with a triple PVD coating for exceptional heat resistance and clean cutting performance. For stainless steels, a BXC TiN-coated option is optimized for low cutting speeds, broad material compatibility, and extended tool life.

• 60° MIR partial threading geometry: Designed to thread internal features in tight spaces while staying compatible with 55° profiles, enabling reliable internal threads in small bores.
• BMK-grade coating with advanced PVD: Sub-micron carbide with a triple-coated finish provides excellent heat resistance and smooth cutting, supporting consistent results across materials.
• Compact reach and access: 5.1 mm minimum diameter with a 15 mm reach lets you reach constrained bores while maintaining rigidity for accurate, clean threading even in challenging layouts.

This combination of small size, robust carbide core, and thoughtfully engineered coatings helps you complete precise threads in restricted spaces, reduces setup and tool-change time, and delivers dependable results in stainless steels and other demanding materials. It’s a practical choice for engineers, machinists, and technicians seeking reliable internal thread performance without sacrificing access or finish quality.
