The Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide bar designed for precision boring and versatile turning tasks. With a minimum diameter of 1.5 mm, a 6 mm reach, and left-hand geometry, it reaches tight bores and challenging features with stability. This tool is part of the MTL BMK grade family and is offered with two coating options to suit different materials and cutting speeds.

Designed for boring and general turning alike, these carbide bars perform reliably with a wide range of materials, including stainless steels. The BXC coating (PVD TiN) is optimized for lower cutting speeds, while the BMK grade features a sub-micron, triple PVD coating for exceptional heat resistance and smooth cutting performance. This makes the tool suitable for everyday shop use across ISO P30-P50 / K25-K40 and ISO K10-K20 material ranges.

• Dual PVD-coated carbide options: Choose BXC TiN for low-speed cuts on stainless steels or BMK’s triple-coated sub-micron grade for high heat resistance and smoother cuts, delivering dependable performance across a wide material range.
• Left‑hand geometry for boring: Optimized for boring operations, providing stable engagement, cleaner holes, and predictable chip flow in challenging bore geometries.
• Ultra-compact size with deep reach: 1.5 mm minimum diameter and 6 mm reach let you access tight bores and confined features without multiple tools, improving setup efficiency and reducing tool changes.

This tiny yet capable tool helps you complete precise boring and light turning tasks with consistent, repeatable results. The carbide construction resists wear and heat, while the coatings extend tool life in demanding materials. The compact profile and proven coating options streamline setups, reduce downtime, and improve surface finish and dimensional accuracy across your job shop or production environment.
