Carmex Carbide Tiny Tool is a left-handed threading tool designed for internal threads in tight spaces, using a 55° MIL partial profile. Its compact form—6 mm minimum diameter with a 22 mm reach—lets you access small bores and hard-to-reach cavities with confidence and precision. This tool is part of a versatile line of partial-profile threading bars and supports a minimum bore diameter of 1.2 mm (0.05 in) for small, precise threads.

• Left-Hand, compact reach: The 6 mm minimum diameter and 22 mm reach are optimized for accessing internal threads in tight bores without repositioning the workpiece, improving setup efficiency and reducing handling time.
• Two coating options for versatile performance: BXC TiN coating provides low cutting speeds, ideal for stainless steels (ISO P30-P50 / K25-K40). BMK is a sub-micron grade with advanced PVD triple coating (ISO K10-K20) delivering extremely high heat resistance and smooth cutting across materials.
• 55° partial-profile compatibility with small bores: Specifically designed for 55° MIL partial-profile threads and a minimum bore diameter of 1.2 mm (0.05 in), delivering consistent thread quality in compact assemblies.

With its small footprint and optimized coatings, this tool helps you produce precise internal threads quickly and consistently in tight spaces, reducing setup time and scrap. The dual coatings extend tool life and adapt to stainless steels and other materials, so you can swap between jobs without changing tooling. Built for reliability in busy shops and demanding projects, it supports faster turnaround from prototype to production with dependable, repeatable results.
