Meet the Carmex Carbide Tiny Tool, a compact solid carbide boring bar engineered for tight bores and precision turning. Perfect for engineers, machinists, and hobbyists, it delivers dependable performance in small-feature work while confidently handling general turning tasks. With an 8.1 mm minimum diameter, a 15 mm reach, and a nose radius of R0.2, this tool provides exacting control in stainless steels and a wide range of materials.

• Compact geometry for tight bores: 8.1 mm minimum diameter, 15 mm reach, and R0.2 nose radius enable access to confined features, reducing secondary operations and fixture changes.
• BMK grade with advanced PVD coating: Sub-micron carbide with a triple PVD coating delivers exceptional heat resistance (ISO K10–K20) and smooth cutting for longer tool life and consistent performance.
• General-purpose performance across materials: While optimized for boring, this bar handles general turning and works well on stainless steels and a wide range of alloys, offering reliable results and fewer tool swaps.

This tiny carbide boring bar is designed to streamline workflows in production and prototyping alike. Access tight internal features with confidence, enjoy durable cutting action under high-temperature conditions, and achieve repeatable diameters and finish quality across multiple jobs—all from a single, compact tool.
