Carmex Carbide Tiny Tool - Boring Bar - MTL - BXC Grade - 6.1mm Minimum Diameter x 22mm Reach x R0.1 (Left Hand)

The Carmex Carbide Tiny Tool - Boring Bar is a compact solid carbide bar designed for precision boring and general turning. With a 6.1 mm minimum diameter, 22 mm reach, and left-hand R0.1 geometry, it delivers stable entry and consistent finishes in tight bores. Available in two advanced coating grades, it adapts to your material and speed needs: BXC with a PVD TiN coating for low cutting speeds and strong performance with stainless steels (ISO P30-P50 / K25-K40); or BMK, a sub-micron grade with a rugged PVD triple coating for high heat resistance and smooth cutting across all materials.

• Compact, tight-bore capability: The tiny tool reaches 22 mm and supports a 6.1 mm minimum diameter, enabling precise boring in confined holes with steady, predictable material removal.
• Two coating grades for versatile performance: BXC TiN coating is optimized for low cutting speeds and excels with stainless steels (ISO P30-P50 / K25-K40); BMK is a sub-micron grade with triple PVD coating for high heat resistance and smooth cutting across materials.
• Left-hand geometry for efficient turning: Left-hand R0.1 nose geometry supports smooth entry and clean finishes in boring and turning operations, reducing setup time and improving surface quality.

This tiny carbide tool helps you achieve precise holes with minimal setup and reliable finishes across stainless steels and other materials. Whether drilling tight bores in production parts or performing finishing passes, the dual coating options provide durability and consistent performance under different speeds and temperatures, while the rigid carbide core and optimized geometry minimize chatter and maximize tool life. It’s a dependable choice for engineers, machinists, and hobbyists who demand repeatable results and efficient turning and boring workflows.
