The Carmex Carbide Tiny Tool Boring Bar in MTL TNX Grade is a compact solid carbide tool designed for precision boring and versatile turning tasks in tight spaces. With a 3.1 mm minimum diameter, 15 mm reach, and a left-hand R0.1 nose, it delivers accurate, repeatable cuts in small bores and intricate features. It’s part of the Carmex Tiny Tool line and offers coating options to suit different materials and speeds, including BXC TiN for stainless steels and BMK triple-coated for high-heat performance.

• Compact micro-diameter with extended reach: The 3.1 mm minimum diameter and 15 mm reach let you access tight bores and features without sacrificing rigidity, enabling precise internal cuts in confined spaces.
• Coatings tuned for performance: Choose BXC with PVD TiN for dependable cutting of stainless steels at lower speeds, or BMK with a sub-micron, triple PVD coating for high heat resistance and smooth cutting across a wide material range.
• Left-hand orientation and precise nose radius: The R0.1 nose radius and left-handed geometry provide consistent surfaces and predictable tool behavior in boring and turning applications.

This tiny carbide tool helps you complete tight-bore jobs faster with fewer tool changes, longer tool life, and reliable finishes across materials. The robust carbide core resists wear under demanding cuts, while the coatings minimize friction and heat, improving productivity and reducing downtime. Whether you’re machining stainless parts or general-purpose components, this tool delivers consistent performance and easy setup for everyday shop needs.
