The Carmex Carbide Tiny Tool is a compact boring bar crafted from solid carbide for precise boring and reliable general turning. With a 6.1 mm minimum diameter, a 15 mm reach, and a nose radius of R0.05, it delivers accurate, clean cuts in tight bores.

This tool line is designed for engineers, machinists, and hobbyists who value repeatable results in stainless steels and a wide range of materials. It offers two coating grades to match your cutting conditions: BXC TiN-coated for low-speed work and smoother finishes, and BMK with advanced PVD triple coating (ISO K10-K20) for extremely high heat resistance and versatile, all-material performance.

• Compact carbide boring bar with precise geometry: Delivers tight bore capability and stable cuts in confined spaces thanks to the small 6.1 mm minimum diameter, 15 mm reach, and R0.05 nose radius.
• Two coating grades to match materials: BXC TiN-coated for low-speed cuts and stainless steels (ISO P30-P50 / K25-K40); BMK with triple PVD coating (ISO K10-K20) for high-heat, general-purpose use.
• Designed for reliability and long tool life: Solid carbide construction and advanced coatings reduce wear, extend tool life, and promote smooth cutting, reducing downtime in demanding boring and turning applications.

Together, this tiny tool helps you achieve accurate bore dimensions, smoother surface finishes, and consistent results across a range of materials, while minimizing setup time and tool changes. It’s a dependable choice for production environments and precision work alike.
