Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide tool designed for small-diameter boring and general turning. It features a 6.1 mm minimum diameter, 35 mm reach, and a precise R0.2 tip radius, enabling accurate holes in tight spaces with a clean finish.

Part of the Carmex MTR line, this tiny boring bar is available in two coating grades to match your material and cutting conditions. BXC Grade uses a PVD TiN coating optimized for low cutting speeds and performs well with a wide range of stainless steels (ISO P30-P50 / K25-K40). BMK Grade employs a sub-micron grade with an advanced PVD triple coating, delivering extremely high heat resistance and smooth cutting for general-purpose use across materials.

• Compact, tight-pocket boring capability: With a 6.1 mm minimum diameter, 35 mm reach, and a clean R0.2 radius, this tool reaches into confined bores and corners while maintaining rigidity and consistent hole quality.
• Coating options for versatile material performance: BXC TiN coating protects the tool in stainless steels at low speeds, while BMK with triple PVD coating provides high heat resistance and smooth cutting across a wide material range, extending tool life and reducing finishing passes.
• Durable carbide for reliable results: Solid carbide construction delivers repeatable dimensions and steady performance in boring and turning, minimizing downtime and ensuring consistent results across jobs.

Together, these features help you complete precision holes and smooth finishes more quickly, improve workflow efficiency, and rely on a tool engineered for longevity. Whether you’re in a high-mix shop or a dedicated production environment, the Carmex Tiny Tool offers predictable performance and confidence across stainless steels and other materials.
