The Carmex Carbide Tiny Tool is a compact solid carbide boring bar designed for precision work in tight spaces. With a 3.1 mm minimum diameter, a 15 mm reach, and a nose radius of R0.1, it’s built to access small bores and deliver clean, accurate results in turning and boring tasks.
This tool is ideal for engineers, machine shops, tradespeople, and hobbyists who need a reliable, versatile boring bar that performs well on stainless steels and a broad range of other materials. The product family includes two coated carbide grades, each tailored to different cutting conditions: BXC for efficient low-speed cutting on stainless steels, and BMK for high-heat performance and smooth cutting across materials.
- Small-diameter, long-reach geometry: 3.1 mm minimum diameter with 15 mm reach and a precise R0.1 nose radius for accessing tight bores and producing smooth finishes in confined spaces.
- BXC Grade coating for stainless steel performance: PVD TiN coating optimized for low cutting speeds, delivering reliable wear resistance and consistent results on a wide range of stainless steels (ISO P30-P50 / K25-K40).
- BMK grade for high-heat, versatile cutting: Sub-micron grade with advanced PVD triple coating (ISO K10-K20) offering exceptional heat resistance and smooth cutting, making it a solid general-purpose choice for many materials.
This tiny tool is designed to stand up to demanding workloads, providing steady performance, predictable tool life, and minimal downtime. Its coated carbide construction helps maintain sharpness and finish quality over extended runs, giving you confidence to tackle small-diameter boring and turning tasks with precision.
