Carmex Carbide Tiny Tool - Boring Bar - MTR - BMK Grade - 1.5mm Minimum Diameter x 6mm Reach x R0

The Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide bar designed for precision boring and versatile turning tasks. With a 1.5 mm minimum diameter and a 6 mm reach, it excels in tight bores, small pockets, and cramped setups while delivering stable, consistent cuts. The R0 nose radius supports precise hole profiles and clean finishes, making it suitable for engineers, machinists, hobbyists, and shop floors alike.

This tiny tool is offered in two specialized coating grades to match your material and speed needs. The BXC grade features a PVD TiN coating optimized for low cutting speeds and excellent performance on a wide range of stainless steels (ISO P30–P50 / K25–K40). The BMK grade uses a sub-micron core with a triple PVD coating (ISO K10–K20), delivering exceptional heat resistance and smooth cutting for maximum performance across all materials. Both options are built to minimize wear and extend tool life in demanding environments.

• Ultra-compact bore-ready design: Slim 1.5 mm diameter with a 6 mm reach fits into tight bores and restricted spaces, reducing setup time and increasing stability for precise hole quality.
• Two coating grades for versatile material handling: Choose BXC TiN for stainless steels at lower speeds, or BMK for high-heat, all-material capability, giving you reliable performance across a broad range of jobs.
• R0 nose radius with solid carbide core: The sharp nose and robust carbide construction deliver clean finishes, reduced chatter, and predictable, repeatable results in both boring and general turning.

By providing a purpose-built solution for small-diameter bores and demanding materials, the Carmex Tiny Tool streamlines your workflow: fewer tool changes, longer tool life, and consistent surface finishes across projects. It’s a reliable, precision-focused option for professionals who need dependable performance in tight spaces, whether you’re drafting prototypes, performing maintenance work, or delivering high-precision production parts.
