Carmex Carbide Tiny Tool is a compact, solid carbide boring bar engineered for precise small-diameter bores and reliable general turning. Designed for tight spaces, it features a 4.1 mm minimum diameter, 10 mm reach, and an R0.1 tip radius—perfect for micro boring and finishing passes where steadiness and precision matter. Built in BMK Grade, it delivers exceptional heat resistance and smooth cutting performance, making it a versatile general-purpose option for all materials.

• BMK Grade with PVD triple coating: Sub-micron structure and advanced PVD triple coating (ISO K10–K20) provide outstanding heat resistance and smooth cutting, helping maintain edge quality and extend tool life across a wide range of materials.
• Small-diameter, long-reach geometry: With a 4.1 mm minimum diameter, 10 mm reach, and an R0.1 nose radius, it excels at tight bores and precise finishing in confined spaces.
• Versatile boring and turning capability: Primarily designed for boring but capable of general turning, offering a single dependable tool for multiple machining tasks and reducing tool changes.

This tool supports efficient workflows by delivering consistent hole quality and smooth finishes, even on challenging materials. The durable BMK coating reduces wear and friction for reliable performance over long runs, while the compact form factor simplifies setup and alignment in crowded setups—helping you complete micro-bore projects with confidence and repeatable results.
