The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precision in small-diameter work. With a 6.1 mm minimum diameter and a 15 mm reach, it fits tight bores while delivering steady cutting performance for boring and light turning tasks.

Two PVD-coated carbide grades expand its versatility: BXC TiN-coated grade optimized for low cutting speeds and stainless steels (ISO P30-P50 / K25-K40), and BMK grade with a sub-micron structure and triple PVD coating, delivering exceptional heat resistance and smooth cutting across a wide range of materials. The tool features a left-hand orientation and a refined R0.2 corner radius for consistently clean finishes in restricted setups.

• Compact bore-ready geometry: Access tight bores with a 6.1 mm minimum diameter and 15 mm reach, while maintaining rigidity for stable, repeatable cuts in small-diameter work.
• Two coating grades for versatile materials: BXC TiN-coated grade minimizes wear at low cutting speeds and pairs well with stainless steels (ISO P30-P50 / K25-K40); BMK sub-micron grade with triple PVD coating delivers high heat resistance and smooth cutting across most materials, giving you reliable performance across tasks.
• Left-hand edge with R0.2 corner radius: The left-handed cutting geometry and tight R0.2 corner promote clean finishes and predictable results when used in standard left-hand boring setups.

Designed for professionals and hobbyists alike, the Carmex Tiny Tool helps you finish small bores with confidence and consistency. The rigid carbide bar, combined with specialized PVD coatings, supports smooth cutting, clean finishes, and stable performance across stainless steels and other materials. Easy to set up in standard boring and turning setups, it helps reduce setup time and rework, improving overall workflow and results in everyday machining tasks.
