The Carmex Carbide Tiny Tool is a solid carbide boring bar designed for small-diameter holes and tight work envelopes. With an 8.1 mm minimum diameter, 22 mm reach, and a left-hand R0.2 nose, it delivers precise boring and versatile turning in constrained setups, built from MTL K20-grade carbide for durability.

• Small-diameter, long-reach boring: 8.1 mm minimum diameter and 22 mm reach in a left-hand configuration provide precise holes in tight spaces and easy access to deep bores, reducing the need to switch tools.
• Dual PVD coating options for broader material compatibility: Choose BXC TiN-coated grade for stable cutting at lower speeds on stainless steels (ISO P30–P50 / K25–K40), or BMK sub-micron grade with triple PVD coating for excellent heat resistance and smooth cutting across a wide range of materials (ISO K10–K20).
• Rigid carbide construction for reliable performance: Made from solid carbide (MTL K20 grade), this tool delivers a strong edge life and consistent results in demanding boring and turning scenarios.

With the Carmex Tiny Tool, you gain a dependable, single-tool solution for accurate, repeatable boring and turning tasks. The compact 8.1 mm bore capability lets you access tight pockets and fixtures, while the coating option reduces wear and heat, extending tool life and reducing downtime. The left-hand geometry and R0.2 nose promote clean entry and smooth finishes, delivering repeatable hole sizes and better surface quality across stainless steels and other materials. This translates to faster setups, fewer tool changes, and more consistent results in production and workshop environments.
