Carmex Carbide Tiny Tool - Boring Bar - MTR - BXC Grade is a compact solid carbide bar designed for precise boring and general turning on small parts. With a minimum diameter of 3.7 mm, a reach of 15 mm, and a nose radius of R0.15, it delivers accurate hole creation in tight spaces without sacrificing rigidity.

Part of Carmex's solid carbide bar lineup, the BXC grade uses a PVD TiN coating optimized for low cutting speeds. This coating provides enhanced wear resistance and stable performance when machining stainless steels (ISO P30-P50 / K25-K40), helping extend tool life across jobs.

• PVD TiN-coated BXC grade for low-speed cutting: Improves wear resistance and maintains stable, precise cuts at lower speeds, especially on stainless steels (ISO P30-P50 / K25-K40).
• Compact 3.7 mm diameter with 15 mm reach: Enables access to tight internal features and deep bores in small parts, reducing the need for tool changes.
• R0.15 nose radius for smooth, accurate finishes: Delivers gentle material removal and clean bore walls with good surface finish.

Designed for dependable, repeatable boring performance in small parts, this tool combines hard carbide, precise geometry, and TiN coating to extend life, reduce downtime, and improve hole quality in challenging tasks. It’s a reliable choice for engineers, machinists, and hobbyists who value consistent performance in compact setups.
