The Carmex Carbide Tiny Tool – Boring Bar is a compact, precision carbide tool designed for internal boring on small-diameter workpieces. It features a 6.1 mm minimum diameter, 40 mm reach, and a left-hand orientation with an R0.2 corner radius, enabling deep access and tight control in narrow bores.

Designed for versatility, it also handles general turning tasks. The BXC grade uses a PVD TiN coating optimized for low cutting speeds, delivering reliable performance with a broad range of stainless steels (ISO P30-P50 / K25-K40) and helping maintain a smooth surface finish even at demanding feeds. This makes it a dependable choice for precision shops and job sites that require consistent results from a single tool.

• Compact internal-boring capability: 6.1 mm minimum diameter, 40 mm reach, and left-hand orientation with an R0.2 corner radius—built for deep access and precise, repeatable cuts in tight bores.
• BXC TiN-coated carbide for stainless steels at low speeds: PVD TiN coating reduces wear and extends tool life while delivering clean finishes on a wide stainless steel range (ISO P30-P50 / K25-K40).
• Versatile, reliable performance for multiple materials: Although optimized for boring, the design supports general turning tasks, giving you a flexible tool that maintains consistent results across common metals.

With this tool, you can complete small-bore projects more efficiently, reduce setup adjustments, and achieve repeatable finishes on stainless steels and other materials. The combination of compact reach, a proven coating, and precise geometry translates to higher productivity, fewer tool changes, and reliable results in demanding shop environments.
