The Carmex Carbide Tiny Tool is a compact boring bar designed for precision boring and reliable turning. As part of the TNX Grade family, it delivers consistent performance from setup to finish with a 6.1 mm minimum diameter, 30 mm reach, and a 0.2 mm corner radius to access tight bores while maintaining dimensional accuracy.

Two coated grades tailor the tool to different materials and speeds: the BXC grade features a PVD TiN coating for smoother cutting at low speeds and strong results with stainless steels (ISO P30-P50 / K25-K40); the BMK grade uses a sub-micron substrate with a triple PVD coating for excellent heat resistance and a smooth cut across a broad range of materials (ISO K10-K20).

• Ultra-compact boring bar geometry: The 6.1 mm minimum diameter, 30 mm reach, and R0.2 corner radius enable precise, controlled boring in confined bores and tight tolerances.
• Coating options tailored for performance: Choose BXC with TiN for smoother cutting at low speeds on stainless steels or BMK with a sub-micron, triple coating for high heat resistance and versatility across materials.
• Reliable carbide construction for demanding jobs: Solid carbide provides rigidity and consistent cutting action, delivering dependable tool life and stable finishes in turning and boring applications.

Whether you’re tackling tight-feature bores in stainless steel or performing general turning on a variety of materials, this tiny tool supports fast setups, predictable results, and reduced downtime. The TNX Grade family, paired with the two coating options, offers a flexible, durable solution for high-precision machining, improving part quality and workflow efficiency in professional shops and skilled workshops alike.
