The Carmex Carbide Tiny Tool - Boring Bar, MTR - TNX Grade, is a compact, solid carbide tool built for precision small‑diameter bores and reliable turning in tight spaces.

It features a 5.1 mm minimum bore diameter, 15 mm reach, and a nose radius of R0.1 to deliver consistent hole sizes and smooth finishes. The tool supports demanding jobs across stainless steels and other materials, making it a versatile choice for both production environments and shop floors.

• Tiny-diameter precision for tight bores: With a 5.1 mm minimum diameter, 15 mm reach, and a precise R0.1 nose, you achieve accurate, repeatable holes in confined spaces and maintain tight tolerances across multiple setups.
• Coated carbide versatility for stainless steels and high-heat materials: Engineered with advanced PVD coatings—BXC TiN for low-speed cutting on stainless steels (ISO P30-P50 / K25-K40) and BMK triple-coated for high heat resistance (ISO K10-K20)—to deliver reliable cutting, reduced wear, and smoother finishes across a broad material range.
• Durable carbide core for consistent performance: The solid carbide construction provides excellent wear resistance, stable cutting forces, and long tool life, helping you maintain quality finishes and repeatable results through demanding jobs.

By choosing the Carmex Tiny Tool, you gain a reliable, compact boring bar that reduces tool changes, improves hole quality, and enhances productivity. The dual coating approach protects against wear and heat, while the carbide core delivers consistent performance from first cut to last. In tight work zones and with challenging materials, this tool helps you complete projects faster with confidence and repeatable results.
