The Carmex Carbide Tiny Tool is a precision solid carbide boring bar designed for tight bores and delicate turning tasks. Built in the MTR family with K20 grade, this compact tool is as versatile as it is capable, making it suitable for engineers, technicians, and hobbyists alike.

With a 5.1 mm minimum diameter, 30 mm reach, and an R0.1 tip radius, it delivers accurate starts and clean finishes in confined spaces, while still handling general turning jobs when needed.

• Compact tiny-tool geometry for tight bores: Designed for tight internal work, the 5.1 mm diameter, 30 mm reach, and R0.1 radius help you maintain precise bore size and smooth finishes in restricted cavities.
• Coating options for versatile performance: Choose BXC TiN coating for low cutting speeds and good results with a wide range of stainless steels (ISO P30–P50 / K25–K40), or BMK sub-micron coating with a triple PVD layer for high heat resistance and smooth cutting across many materials.
• Rigid carbide construction for durability: Solid carbide builds deliver wear resistance and dimensional stability, supporting reliable, repeatable results across boring and general turning tasks.

Together, these features help you complete small-diameter boring and turning tasks more efficiently, with dependable tool life, predictable finishes, and material-ready performance. The dual coating options let you tailor the tool to your material and cutting conditions, while the tight geometry ensures consistent results in confined bores and deep features.
