The Carmex Carbide Tiny Tool is a compact solid carbide boring bar designed for tight internal bores and precision turning. With a 2.1 mm minimum diameter, 5 mm reach, and a left-hand orientation (R0.05 nose radius), it fits into narrow cavities and small-scale projects while delivering clean, accurate finishes.

Designed primarily for boring, it also handles general turning with dependable results. The BXC-grade coating uses a PVD TiN finish to support low cutting speeds and works well with a wide range of stainless steels (ISO P30-P50 / K25-K40), helping you maintain consistent performance across challenging materials.

• Compact, precise geometry for tight interiors: Access 2.1 mm bores with a 5 mm reach and a 0.05 mm nose radius to achieve controlled cuts in confined spaces and consistent surface finish.
• BXC-grade TiN coating for low-speed cutting: PVD TiN coating reduces wear at low cutting speeds, enhancing reliability and tool life when working with stainless steels.
• Left-hand orientation for compatible setups: Specifically designed for left-handed tooling scenarios, improving cutting stability and chip control in miniature boring and turning tasks.

This tiny boring bar helps you complete small-diameter work with fewer tool changes and consistent results. Its focused geometry and TiN-coated performance support smoother cuts, better surface finishes, and reliable operation in tight spaces, making it a trusted choice for precision machining, micro-fabrication, and hobbyist projects alike.
