The Carmex Carbide Tiny Tool is a compact solid carbide boring bar designed for precision bore work and reliable turning. With a 4.1 mm minimum diameter, a 30 mm reach, and a nose radius of R0.2, it delivers tight geometries in small bores and consistent performance in demanding materials.

Part of a versatile line, this tool offers two coating grades to match your material and speed. The BXC option uses a PVD TiN coating optimized for low cutting speeds and excellent performance with stainless steels (ISO P30-P50 / K25-K40). The BMK option is a sub-micron grade with an advanced PVD triple coating (ISO K10-K20) that delivers high heat resistance and smooth cutting for broad material ranges. This combination gives you dependable performance from light-duty to more challenging machining.

• Compact, small-diameter design: The 4.1 mm minimum diameter and 30 mm reach let you access tight bores and cramped features while maintaining stable cutting and precise geometry.
• Two high-performance coatings for versatility: BXC TiN supports low-speed cutting in stainless steels, while BMK’s triple PVD coating provides exceptional heat resistance for demanding materials, extending tool life.
• Nose radius of R0.2 for smooth finishes: The fine nose radius helps reduce chatter and deliver consistent, high-quality surface finishes across a range of materials.

This tiny, durable boring bar helps streamline workflows by handling both boring and light turning tasks with consistent results. The dual-coating options offer flexibility across materials, helping reduce tool changes and improve finish quality, so you can achieve reliable performance from setup to part completion.
