Carmex Carbide Tiny Tool - Boring Bar is a compact solid carbide solution designed for precision boring in tight spaces. With a 2.1 mm minimum diameter, 10 mm reach, and a left-hand orientation, this tiny bar is ideal for small-diameter bores and delicate turning tasks. Its rigid carbide construction delivers consistent finishes and long tool life in demanding shop environments.

Two coated grades are available to optimize performance across materials and speeds. BXC is a TiN-coated grade designed for low cutting speeds and works well with a wide range of stainless steels (ISO P30-P50 / K25-K40). BMK is a sub-micron grade with advanced PVD triple coating, offering extremely high heat resistance for maximum performance and smooth cutting operation. General purpose for all materials.

• TiN-coated BXC grade for low-speed stainless steel work: Optimized for low cutting speeds and stainless steels to reduce wear and heat buildup, helping maintain a clean bore finish and longer tool life.
• BMK sub-micron grade with triple PVD coating for high-heat performance: Delivers outstanding heat resistance for dependable performance across a broad range of materials with smooth cutting action.
• Compact, versatile boring bar for boring and turning: Solid carbide design provides rigidity and precise results in tight bores and small-diameter turning tasks, enabling reliable operation with minimal setup.

Whether you’re finishing fine bores, performing general turning, or working in limited-access areas, this tiny tool helps you achieve accurate diameters, smooth surface finishes, and consistent results. Tailor performance to your material and speed with the two coatings, and count on Carmex’s proven carbide tooling for reliable, repeatable results across jobs.
