The Carmex Carbide Tiny Tool - Boring Bar is a compact solid carbide cutting tool designed for precision boring and small-diameter turning. With a 2.1 mm minimum diameter, a 5 mm reach, and a nose radius of R0.05, it excels at tight bores and fine finishes in a range of materials. This is part of a versatile line that can handle boring as well as general turning tasks.

The tool line offers two coating families to suit different materials and cutting speeds. BXC is a PVD TiN-coated grade optimized for low cutting speeds and especially effective with stainless steels (ISO P30-P50 / K25-K40). BMK is a sub-micron grade with advanced PVD triple coating, delivering high heat resistance and exceptionally smooth cutting for general-purpose use across materials.

• Coating options tailored to material and speed: Choose BXC TiN for reliable performance on stainless steels at low speeds, extending tool life and reducing edge buildup; or BMK’s triple PVD coating for high heat resistance and consistently smooth cuts across a wide range of materials.
• Ultra-compact geometry for precise small bores: 2.1 mm minimum diameter with a 5 mm reach and a fine R0.05 nose radius enables accurate, repeatable boring and turning in tight cavities and complex geometries.
• Solid carbide durability with smooth cutting: Built from hard carbide and finished with PVD coatings to resist heat and wear, delivering steady cutting performance and clean finishes even at demanding speeds.

This tool is designed to improve your workflow by delivering reliable, repeatable results in small-diameter bores and precision turning. Its coating options help extend tool life, reduce downtime, and maintain tight tolerances across stainless steels and other challenging materials, so you can complete jobs faster with confidence.
