Carmex Carbide Tiny Tool - Boring Bar - MTL - BXC Grade - 3.1mm Minimum Diameter x 10mm Reach x R0.05 (Left Hand)

The Carmex Carbide Tiny Tool is a solid carbide boring bar designed for precision internal work and general turning. With a compact 3.1 mm minimum diameter, a 10 mm reach, and a left-hand orientation at R0.05, it fits tight spaces while delivering clean, repeatable cuts.

This tool family offers two coating options to match your material and speed requirements. The BXC grade features a PVD TiN coating optimized for low cutting speeds and excels with a wide range of stainless steels (ISO P30-P50 / K25-K40). The BMK grade uses a sub-micron, advanced PVD triple coating for extremely high heat resistance and smooth cutting, making it a versatile general-purpose choice for all materials.

• Ultra-compact bore capability: Designed for small-diameter boring with a 3.1 mm minimum diameter and 10 mm reach, enabling precise internal cuts in confined spaces.
• Versatile coating options for material range: Choose BXC TiN for stainless steels at lower speeds or BMK’s triple PVD coating for high heat resistance and smooth cutting across a broad range of materials.
• Left-hand geometry with a precise edge: Left-hand orientation paired with a controlled R0.05 radius supports consistent toolpaths and reliable finishes in boring operations.

This tiny carbide tool helps you achieve accurate, repeatable internal cuts in tight spaces while offering coating choices that optimize performance for stainless steel and multi-material work. Its solid construction and carefully engineered geometry provide dependable results, making it a solid choice for engineers, machinists, and hobbyists tackling small-bore challenges.
