The Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide bar designed for precise boring and versatile turning. It’s ideal for engineers, buyers, tradespeople, and hobbyists who need accurate holes in tight spaces, delivering clean, dependable results across a range of materials.

As part of Carmex’s solid carbide tool line, these bars are offered with coating grades that optimize performance for different 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 uses sub-micron carbide with advanced PVD triple coating, delivering extremely high heat resistance for maximum performance and smooth cutting, with general-purpose applicability for all materials. The tool is configured in a left-hand orientation with a 6.1 mm minimum diameter, 15 mm reach, and a R0.2 nose radius, suitable for tight bore work.

• Coating options for versatile material compatibility: BXC TiN coating supports low-speed cutting and excels with stainless steels (ISO P30-P50 / K25-K40); BMK’s sub-micron, triple-coated design delivers high heat resistance and smooth cutting for broad material use.
• Optimized boring geometry with turning versatility: Designed primarily for boring, yet capable of general turning; left-hand configuration with 6.1 mm minimum diameter, 15 mm reach, and a precise R0.2 nose radius for consistent bore finishes in confined spaces.
• Rigid carbide construction for reliable performance: Solid carbide core provides stiffness and wear resistance, enhanced by coatings to minimize wear and extend tool life across demanding jobs.

With these bars, you gain a dependable blend of rigidity, wear resistance, and coating-driven performance that supports accurate bores, smooth cuts, and longer tool life. The compact form factor and precise nose radius help you achieve consistent results in tight spaces, reducing rework and downtime on production runs or maintenance tasks.
