Carmex Carbide Tiny Tool - Boring Bar is a compact, high-precision solid carbide bar designed for tight internal bores and general turning tasks. With a 2.1 mm minimum diameter, 10 mm reach, and a nose radius of R0.15, it delivers accurate bore finishes in small parts and challenging geometries. This tool is ideal for engineers, machinists, hobbyists, and anyone working on compact components where precision matters.

Available in high-performance coating grades, the BXC TiN-coated option is optimized for low cutting speeds and performs well with stainless steels (ISO P30-P50 / K25-K40), while the BMK sub-micron grade uses a triple-layer PVD coating for exceptional heat resistance and smooth cutting across a broad material range. Use the grade that best matches your material and speed needs for reliable, consistent results.

• Ultra-compact bore capability: 2.1 mm minimum diameter, 10 mm reach, and R0.15 nose radius enable precise internal bores and smooth finishes in tight spaces, reducing the need for additional operations.
• Coating options tuned for performance: BXC TiN coating enhances wear resistance at low speeds for stainless steels; BMK grade adds sub-micron carbide with triple PVD coating for high heat resistance and versatile cutting across materials.
• Durable construction for long tool life: solid carbide core with advanced coatings delivers consistent wear resistance, minimizes tool changes, and maintains stable cutting in boring and turning tasks.

This tiny boring bar helps you achieve accurate bores, smoother surface finishes, and reliable, repeatable results while simplifying setup and reducing downtime. Its hardened carbide core and coated surface stand up to demanding materials and repetitive use, giving you confidence to tackle tight tolerances and challenging parts without compromising workflow. Whether prototyping or running production, this Carmex Tiny Tool integrates easily with standard tooling setups to deliver dependable performance when it matters most.
