Carmex Carbide Tiny Tool - Boring Bar - MTR - BXC Grade - 2.1mm Minimum Diameter x 5mm Reach x R0.15

Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide tooling option designed for precise internal boring and light turning in tight spaces. With a 2.1 mm minimum diameter, a 5 mm reach, and an R0.15 corner radius, this tiny tool delivers consistent cuts in confined bores while maintaining tool strength and stability.

Available in two advanced grades, it covers a broad range of materials and speeds. BXC is a PVD TiN-coated grade optimized for low cutting speeds and works well with a wide range of stainless steels (ISO P30–P50 / K25–K40). BMK is a sub-micron grade with an advanced PVD triple coating (ISO K10–K20), offering exceptionally high heat resistance and smooth cutting for maximum performance across materials.

• Tiny, precise dimensions: 2.1 mm minimum diameter with a 5 mm reach and R0.15 radius enable internal bores and small-diameter features to be machined with accuracy in constrained spaces.
• Two high-performance grades for versatility: BXC provides reliable cutting at lower speeds on stainless steels, while BMK delivers exceptional heat resistance and smooth cutting for a wide material range.
• Optimized geometry for dependable results: The compact form and proven carbide geometry reduce chatter and improve surface finish, ensuring consistent bore quality and predictable tool life.

This combination of size, coatings, and geometry helps you complete tight-turning applications faster, with fewer tool changes and more consistent finishes. It’s a reliable choice for engineers, machinists, and hobbyists working in constrained setups, whether you’re engraving small features, cleaning up internal bores, or preparing precision components across stainless steels and other materials.
