The Carmex Carbide Tiny Tool is a solid carbide boring bar engineered for precision in tight spaces. While its primary design is for boring applications, it also handles general turning tasks with confidence. With a 3.1 mm minimum diameter, a 10 mm reach, and a nose radius of 0.1 mm, this compact tool delivers clean, repeatable holes and smooth cutting in confined bores—perfect for engineers, machinists, and hobbyists who demand reliable results in small, tricky work areas.

• Tiny, rigid boring capability: Access constricted bores and intricate pockets with a compact 3.1 mm diameter and 10 mm reach, while the 0.1 mm nose radius maintains precise, stable cuts for consistent hole quality.
• Coated carbide for durability and smooth cutting: Choose BXC with PVD TiN for low-speed cutting and stainless steels (ISO P30–P50 / K25–K40), or BMK with a sub-micron grade and triple PVD coating for outstanding heat resistance and very smooth operation across materials.
• Versatile, general-purpose performance: Although optimized for boring, this tool line is well suited for general turning tasks, enabling reliable results across a broad material range and reducing tool changes in mixed-production workflows.

This tiny boring bar is built to support precise hole quality and repeatable performance across demanding applications. Its robust carbide construction, paired with advanced coatings, helps minimize wear, extends tool life, and maintain consistent finishes even in stainless steels and other tough materials. The result is faster setup, fewer passes, and improved overall productivity for your manufacturing or workshop projects.
