The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precise internal bores and small-diameter turning. Its 6.1 mm minimum diameter, 40 mm reach, and R0.2 nose radius give you confident control in tight features, making it ideal for engineers, machinists, and hobbyists who demand accuracy in challenging workpieces. Featuring an MTR - K20 grade option, this bar is built for reliable performance in demanding applications.

Two coating options extend its versatility: BXC is a PVD TiN-coated grade optimized for low cutting speeds and excellent performance with stainless steels (ISO P30-P50 / K25-K40), while BMK uses a sub-micron PVD triple coating for extremely high heat resistance and smooth cutting across a broad material range. This combination lets you tailor the tool to your material and cycle requirements without changing tooling setups.

• Coating versatility for diverse materials: Choose BXC TiN for stainless steels at lower speeds or BMK’s sub-micron PVD triple coating for high-heat, wide-material cutting, giving you reliable performance across many alloys.
• Compact geometry for tight bore work: With a 6.1 mm minimum diameter, 40 mm reach, and a precise R0.2 nose radius, it excels at small internal features and deep pockets with minimal chatter.
• Durable carbide construction: Solid carbide construction delivers long tool life, strong wear resistance, and consistent cuts in demanding boring and general turning tasks.

This combination of versatile coatings, precise tiny-tool geometry, and durable carbide design helps you reduce tool changes, improve hole quality, and maintain steady productivity across stainless steels and other materials. The Carmex Tiny Tool enables reliable, repeatable results in tight tolerances, making it a dependable choice for both professional shops and dedicated home setups.
