Carmex Carbide Tiny Tool - Boring Bar - MTR - TNX Grade - 6.1mm Minimum Diameter x 22mm Reach x R0.2

Carmex Carbide Tiny Tool – Boring Bar is a compact, solid carbide bar designed for tight bores and general turning. Specifically built for the MTR - TNX Grade line, this tiny tool delivers dependable performance where space is at a premium, with a 6.1 mm minimum diameter, 22 mm reach, and a precise R0.2 nose radius for clean, accurate cuts.

The tool family includes coated grades to match different materials and speeds. The BXC grade uses a PVD TiN coating for reliable performance at low cutting speeds and excellent results with many stainless steels. The BMK grade adds a sub-micron carbide with a triple PVD coating for high heat resistance and very smooth cutting, providing versatility across a wide range of materials.

• Compact carbide boring bar with precise reach: When space is tight, this tool's 6.1 mm minimum diameter, 22 mm reach, and R0.2 nose give you direct access to small bores and tight interiors, helping you finish accurate features on the first pass.
• BXC TiN-coated grade for low-speed cutting: Optimized for low cutting speeds and a broad range of stainless steels, this coating reduces wear and built-up edge while helping maintain dimensional accuracy in challenging materials.
• BMK sub-micron grade with triple PVD coating: Designed for maximum heat resistance, this grade delivers smooth cutting and reliable performance across materials, supporting higher-speed finishing and general-purpose tasks without frequent tool changes.

With its precise geometry and dual-grade coating options, the Carmex Tiny Tool helps you complete boring and turning tasks more efficiently. Expect cleaner finishes, consistent hole sizes, reduced tool wear, and fewer setup changes, whether you’re working stainless steel, alloy steels, or other common metals. The result is improved workflow, less downtime, and dependable performance in demanding shop environments.
