Carmex Carbide Tiny Tool - Boring Bar - MTR - BXC Grade - 5.1mm Minimum Diameter x 10mm Reach x R0.2

The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precision internal work and versatile turning in tight spaces. With a 5.1 mm minimum diameter, a 10 mm reach, and a nose radius of R0.2, this tool delivers accurate, repeatable results in confined bores and hard-to-reach features.

The tool line includes two performance grades to match your material and speed needs. BXC is a TiN-coated grade optimized for low cutting speeds and performs well with a wide range of stainless steels (ISO P30–P50 / K25–K40). BMK offers a sub-micron grade with a advanced PVD triple coating, delivering exceptional heat resistance for maximum performance and smooth cutting across materials.

• Compact bore-ready geometry: 5.1 mm minimum diameter, 10 mm reach, and R0.2 nose radius for precise, repeatable internal features in tight cavities.
• BXC Grade with TiN coating for stainless steel at low speeds: Reduces wear and friction, extending tool life while maintaining consistent cuts on common stainless grades.
• BMK Grade with sub-micron carbide and triple PVD coating: High heat resistance and smooth cutting that supports reliable performance across a broad range of materials.

Designed to improve workflow in small-bore projects, the Carmex Tiny Tool helps you achieve accurate finishes with fewer passes, reduce downtime, and depend on steady performance from part to part. Its robust carbide construction and targeted coatings provide confidence for both seasoned machinists and hobbyists working in confined spaces or intricate geometries.
