The Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide tool designed for internal boring and general turning tasks. Its precise left-hand geometry and small-diameter footprint make it ideal for tight bores and delicate finishing passes, while delivering consistent, reliable performance across a range of materials.

Built to cover a spectrum of machining needs, it features a robust carbide core with optimized coatings. The BMK grade offers sub-micron structure with a PVD triple coating for exceptional heat resistance and smooth cutting; the BXC grade uses a PVD TiN coating tuned for low cutting speeds and stainless steel performance.

• BMK sub-micron grade with PVD triple coating: Extremely high heat resistance and smooth cutting action for maximum performance across materials, helping you maintain consistent feeds and finishes.
• PVD TiN coated BXC option for stainless steels: Low-friction coating that extends tool life at lower cutting speeds and works well with a wide range of stainless steels (ISO P30-P50 / K25-K40).
• Left-hand bore geometry with 7.1 mm minimum diameter, 22 mm reach, and R0.2 nose: Enables precise, controlled plunges and deep bores in confined spaces with reliable chip evacuation and predictable results.

This tiny carbide boring bar supports reliable, repeatable results in challenging internal features, reducing downtime and improving workflow. Its durable construction and coatings designed for heat and friction help maintain accuracy over long runs, making it a dependable choice for cramped bores, stainless steel work, and general turning tasks.
