Carmex Carbide Tiny Tool - Boring Bar - MTL - TNX Grade - 8.1mm Minimum Diameter x 15mm Reach x R0.2 (Left Hand)

The Carmex Carbide Tiny Tool is a compact solid carbide boring bar designed for precise, small-diameter bore work and light turning tasks. With an 8.1 mm minimum diameter, a 15 mm reach, and a 0.2 mm nose radius, this left-hand tool fits snug into tight features while delivering clean, repeatable results.

Built for versatility, it belongs to the TNX grade family and supports two coating options to match your material and speed needs: the BXC variant with PVD TiN for low cutting speeds and stainless steels (ISO P30-P50 / K25-K40), and the BMK variant with a sub-micron grade and advanced PVD triple coating for maximum heat resistance and smooth cutting across a wide range of materials.

• Compact micro-boring geometry: Optimized for small-diameter holes with an 8.1 mm minimum diameter, 15 mm reach, and a 0.2 mm nose radius, enabling precise entries and exits in tight features.
• Coatings for durability and performance: Choose BXC TiN for reliable wear resistance at lower speeds on stainless steels, or BMK’s triple PVD coating for excellent heat resistance and smooth cutting across materials.
• Left-hand carbide design for reliable cutting: Specifically engineered for left-handed machining, ensuring steady chip flow, predictable cuts, and consistent surface finish.

This tiny carbide tool helps you tackle boring and turning tasks in confined spaces with confidence, reducing tool changes and delivering repeatable bore quality. The combination of precise geometry, robust coatings, and a hardened carbide core translates to longer tool life, steadier cutting performance, and improved workflow efficiency across a range of materials.
