Introducing Carmex Carbide Tiny Tool, a solid carbide boring bar engineered for precision in tight spaces. Crafted from premium MTR TNX-grade carbide, this compact tool delivers the rigidity and wear resistance you need for accurate boring and reliable turning in confined bores. With a 1.5 mm minimum diameter, 6 mm reach, and a precision R0.1 nose radius, it cleanly enters small cavities while delivering repeatable, high-quality finishes.

Two coated grades give you the right balance of performance for different jobs. BXC is a PVD TiN-coated grade optimized for low cutting speeds and working well with stainless steels (ISO P30-P50 / K25-K40). BMK is a sub-micron grade with advanced triple PVD coating, offering extremely high heat resistance for maximum performance and smooth cutting across a wide range of materials.

• Small-diameter, long-reach geometry: 1.5 mm minimum diameter with 6 mm reach and a precisely rounded R0.1 nose for entering narrow bores and producing clean, accurate corners without extra setup.
• Two coating grades tailored to material and speed: BXC for stable, efficient cutting at low speeds on stainless steels; BMK for high-heat, high-demand cuts across various materials with smooth, consistent performance.
• Rugged solid-carbide construction: MTR TNX-grade carbide delivers stiffness and long tool life, helping you achieve repeatable results in demanding boring and general turning tasks.

This tiny boring bar is designed to boost reliability and productivity in small-diameter work. It supports faster setups, fewer tool changes, and consistent bore quality across stainless steels and other materials, making it a practical choice for engineers, machinists, and hobbyists tackling precision turning and finishing in confined spaces.
