Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precise small-diameter work. Built for tight bores and close-quarters turning, this left-hand tool features a 6.1 mm minimum diameter, 22 mm reach, and a nose radius of R0.2 to deliver accurate, clean cuts in confined spaces.

As part of Carmex’s line of solid carbide bars, this BXC Grade tool uses a PVD TiN coating optimized for low cutting speeds and versatility with stainless steels (ISO speeds P30-P50 / K25-K40). While primarily intended for boring, its robust geometry and coating also support general turning tasks, providing dependable performance across a range of jobs.

• Small-diameter, long-reach design: 6.1 mm minimum diameter with 22 mm reach and R0.2 nose radius enables precise cutting in tight bores and cavities, while preserving surface finish.
• TiN-coated BXC grade for wear resistance: PVD TiN coating reduces friction at low cutting speeds, extending tool life and delivering consistent results when machining stainless steels (ISO P30-P50 / K25-K40).
• Rigid solid carbide construction: Built for reliable performance in boring and turning, providing stable cuts and predictable tool life across demanding jobs.

This tiny boring bar helps you achieve accurate hole dimensions in tight spaces, reduces tooling downtime through durable wear resistance, and delivers smooth cutting action that enhances finish quality. Its compact geometry and robust coating translate to a more efficient workflow, confident performance on challenging small-diameter workpieces, and reliable results across routine boring and turning tasks.
