Carmex Carbide Tiny Tool - Boring Bar for MTL - TNX Grade provides a compact, precision solution for small-diameter boring and light turning tasks. With a 5.1 mm minimum diameter, 15 mm reach, and an R0.2 left-hand cutting tip, this solid carbide bar is designed to perform reliably in tight bores and restricted pockets while delivering consistent hole quality.

This product line offers two high-performance coating options to match your material and speed needs. BXC is a PVD TiN-coated grade optimized for low cutting speeds and excels with a wide range of stainless steels (ISO P30-P50 / K25-K40). BMK is a sub-micron grade with advanced PVD triple coating, delivering extremely high heat resistance for maximum performance and smooth cutting across various materials. General-purpose by design, these bars handle a broad spectrum of turning and boring applications with confidence.

• Dual coating options for versatile material support: Choose BXC TiN for steady performance on stainless steels at lower speeds, or BMK’s triple PVD coating for high heat resistance and smoother cuts across a wider material range.
• Compact, precise boring geometry for tight bores: 5.1 mm minimum diameter, 15 mm reach, and left-hand orientation enable access to small cavities and tight pockets with fewer tool changes and consistent hole quality.
• Left-hand geometry with a sharp, durable nose: The R0.2 nose radius paired with left-hand cutting delivers stable cuts, cleaner finishes, and improved chip control in standard turning/boring setups.

Designed for dependable, repeatable performance, the Carmex Tiny Tool helps you achieve accurate bore dimensions while extending tool life. The carbide construction stands up to heat and wear, and the specialized coatings minimize wear, supporting reliable finishes and reduced downtime. Whether you’re a professional machinist or a hobbyist working on precision parts, this tiny boring bar offers consistent results and confidence at every setup.
