The Carmex Carbide Tiny Tool is a solid carbide boring bar engineered for micro-machining tasks. With a 1 mm minimum diameter and 4 mm reach, it is ideal for small bore work and tight-detail turning. The short, rigid geometry and an R0.05 nose radius help you achieve clean holes and precise features in compact parts. Although designed primarily for boring, it also handles general turning jobs, making it a versatile addition to small-part machines and multi-function setups.

The BXC grade uses a PVD TiN coating optimized for low cutting speeds and a broad range of stainless steels. This coating reduces wear, promotes smoother cutting, and delivers reliable performance in ISO ranges P30–P50 and K25–K40, helping extend tool life in tough materials.

• Ultra-compact geometry for micro bores: 1 mm minimum diameter, 4 mm reach, and an R0.05 nose radius let you access tight cavities and small through-holes with consistent diameter and clean finishes.
• PVD TiN-coated BXC grade for stainless steels: The TiN coating reduces wear at low cutting speeds and works well across a wide range of stainless steels (ISO P30–P50 / K25–K40), giving longer tool life and steadier performance.
• Versatile for boring and lightweight turning: Although built for boring, this bar handles general turning, reducing tool changes and simplifying setups without sacrificing precision or surface finish.

Use this tiny tool to improve your workflow by enabling precise micro bores in small parts, reducing setup time, and delivering consistent finishes across materials. The combination of carbide rigidity, TiN coating, and tailored geometry helps you achieve predictable results, lower downtime, and better part quality in tight-space applications.
