The Carmex Carbide Tiny Tool – Boring Bar is a compact, solid carbide bar designed for precise small-diameter boring and reliable turning. It’s built for a wide audience—from engineers and shop floor technicians to hobbyists—offering a predictable, repeatable bore with a 6.1 mm minimum diameter, 15 mm reach, and a refined R0.05 nose. Ground on a K20-grade carbide core, this tool delivers strong wear resistance and steady performance in demanding materials.

• Compact, high-precision geometry: 6.1 mm minimum diameter, 15 mm reach, and a fine R0.05 nose enable accurate bores and smooth entry in tight spaces.
• Coatings engineered for durability: Choose BXC TiN for low-speed stainless-steel work or BMK’s sub-micron, triple-coated grade for extreme heat resistance and consistently smooth cutting—extending tool life.
• Dual-purpose performance: While optimized for boring, this solid carbide bar handles general turning as well, delivering reliable results across a broad material range.

This combination of a rigid K20 carbide core, purpose-built geometry, and advanced coatings helps you complete bore work more efficiently, with fewer tool changes and a cleaner finish. Whether you’re producing tight bores in stainless components or performing finishing passes on challenging metals, the Carmex Tiny Tool delivers dependable, repeatable results you can trust in everyday machining.
