The Carmex Carbide Tiny Tool is a solid carbide boring bar designed for tight bores and precision turning. Primarily built for boring applications, it also handles general turning tasks, giving machinists a compact, reliable option for small-diameter work. It features a 5.1 mm minimum diameter, 30 mm reach, and a left-hand geometry with a 0.2 mm radius to reach into constrained cavities with confidence.

Two coating options provide optimized performance across materials and speeds. The BXC grade uses a PVD TiN coating for low cutting speeds and works well with a wide range of stainless steels (ISO P30-P50 / K25-K40). The BMK grade is a sub-micron, PVD triple-coated option offering extremely high heat resistance for maximum performance and a smooth cutting action, making it a versatile general-purpose choice for all materials.

• Compact size with deep reach: 5.1 mm minimum diameter and 30 mm reach in a left-hand tool profile (R0.2) to access tight bores without sacrificing rigidity.
• Two advanced coating options: BXC PVD TiN supports low-speed cutting on stainless steels; BMK sub-micron with triple coating delivers high heat resistance and smooth cutting for demanding materials.
• Boring-focused with turning versatility: Designed for reliable boring performance while also handling general turning jobs, reducing tool changes and expanding your single-tool capability.

With its solid carbide construction and tailored coating options, this tiny tool delivers consistent, repeatable results across a broad range of materials. The compact geometry enables access to deep features without compromising rigidity, while the coatings help reduce wear and maintain a smooth, clean cut.
