The Carmex Carbide Tiny Tool is a solid carbide boring bar built for precision boring and dependable turning in a compact form. With a minimum diameter of 6.1 mm, a 40 mm reach, and an R0.2 corner radius in a left‑hand configuration, it excels in tight bores and close‑tolerance work. While designed primarily for boring, these bars also handle general turning, making them a versatile choice for engineers, technicians, and hobbyists who value consistent results in constrained spaces.

Coated for durability and broad material compatibility, this tool line offers two advanced grades. The BXC grade uses a PVD TiN coating optimized for lower cutting speeds and pairs well with a wide range of stainless steels (ISO P30-P50 / K25-K40). The BMK grade employs a sub‑micron structure with a triple PVD coating for exceptionally high heat resistance and smooth cutting performance, providing a reliable general‑purpose option for all materials.

• Coated carbide versatility: Two advanced PVD coatings (BXC TiN and BMK triple coating) extend tool life and deliver reliable performance across stainless steels and other materials, even at varied cutting speeds.
• Compact, long‑reach geometry: 6.1 mm minimum diameter, 40 mm reach, and R0.2 corner radius enable precise bore profiles in tight spaces while maintaining a clean, consistent finish.
• Left‑hand configuration for efficient setups: Left‑hand orientation simplifies toolpaths and enhances cutting stability in boring and turning tasks, helping reduce setup time and chatter.

This combination of small size, durable carbide, and purpose‑built coatings delivers consistent, dependable results day after day. You’ll achieve accurate bore diameters, smoother cuts, and longer tool life, with the flexibility to tackle both dedicated boring work and general turning without swapping tools.
