The Carmex Carbide Tiny Tool Boring Bar is a compact, solid carbide tool designed for internal boring in tight spaces. With a 10.1 mm minimum diameter, a 35 mm reach, and a precise R0.2 nose radius, it enables accurate hole creation in small bores while delivering a clean finish. Although optimized for boring, this bar also handles general turning tasks, making it a versatile addition to any shop kit.

• Two advanced coatings for versatile material compatibility: The BXC TiN coating supports low cutting speeds and excels with stainless steels (ISO P30-P50 / K25-K40), while the BMK sub-micron grade uses a triple PVD coating for extreme heat resistance and smooth cutting across materials, providing reliable performance across a wide range of jobs.
• Compact bore-ready geometry for tight spaces: With a 10.1 mm minimum diameter, 35 mm reach, and a 0.2 mm nose radius, this tiny tool reaches into confined bores and delivers precise, controlled cuts with minimal deflection and chatter.
• Solid carbide durability for consistent results: Built from rigid carbide, it maintains stiffness under demanding cuts, helping you achieve repeatable hole sizes and clean finishes across turning and boring operations.

This tiny boring bar is designed to streamline your workflow: it reduces tool changes, supports reliable performance on stainless steels and other materials, and delivers consistent results in tight bores. The combination of specialized coatings and precise geometry helps you cut more efficiently, finish more parts per shift, and trust your bore dimensions every time.
