Carmex Carbide Tiny Tool – Boring Bar, built on MTR K20-grade solid carbide, is a compact solution for precision boring and light turning. With a 4.1 mm minimum diameter, a 22 mm reach, and a precise R0.05 nose radius, it delivers clean, repeatable cuts in small-diameter bores and intricate features. This tool is designed to cover a range of materials and operations, from stainless steels to general turning tasks.

• Compact bore geometry for tight work: Designed for small-diameter bores, its 4.1 mm minimum diameter, 22 mm reach, and R0.05 nose radius deliver accurate, consistent results in confined spaces.
• Coating options for versatile material support: BXC is a PVD TiN-coated grade optimized for low cutting speeds and stainless steels (ISO P30-P50 / K25-K40). BMK is a sub-micron grade with a triple PVD coating for high heat resistance and smooth cutting across materials (ISO K10-K20).
• Rigid carbide construction for durability: Solid carbide core provides rigidity and wear resistance, delivering steady performance and longer tool life in demanding boring and turning applications.

This Tiny Tool helps you achieve reliable, high-quality holes with minimal setup and consistent results across multiple materials. The coated carbide options manage heat and wear for extended tool life, while the compact form factor fits into tight bores without compromising cutting performance. Ideal for production runs, precision prototyping, and maintenance work where dependable boring and turning performance matters.
