Meet the Carmex Carbide Tiny Tool, a compact solid carbide boring bar designed for precise internal work. While designed primarily for boring, it also handles general turning, making it a versatile choice for engineers, technicians, and hobbyists who need consistent bore diameters and smooth finishes.

With a 5.1 mm minimum diameter, 22 mm reach, and a left-hand geometry with an R0.05 nose radius, this tool is tailored for tight bores. It comes with two coating grades—BXC (PVD TiN) for low cutting speeds and stainless steels (ISO P30–P50 / K25–K40), and BMK (sub-micron with PVD triple coating) for maximum heat resistance and smooth cutting across all materials.

• Coating options for versatile materials: BXC TiN supports low-speed cutting and works well with stainless steels; BMK provides extreme heat resistance and smooth cutting, making the tool suitable for a wide range of materials.
• Compact, precise geometry for tight bores: 5.1 mm minimum diameter, 22 mm reach, and an R0.05 nose radius enable accurate internal cuts in confined spaces with reliable finishes.
• Left-hand cutting geometry for stable boring: The left-hand orientation helps deliver consistent chip flow and predictable bore finishes in typical internal turning setups.

Designed for reliability and efficiency, the Carmex Carbide Tiny Tool helps you achieve precise bore diameters and smooth finishes across materials, while delivering steady performance in tight applications. The dual coatings extend tool life and resistance to heat, supporting longer runs between tool changes, and the compact geometry simplifies setup for internal operations, helping you complete jobs faster with repeatable results.
