Carmex Carbide Tiny Tool - Boring Bar is a compact solid carbide tool designed for tight bores and precise turning. With a 6.1 mm minimum diameter, 30 mm reach, and a nose radius of R0.2 in a left-hand configuration, this bar delivers accurate, consistent cuts in small-diameter workpieces. It’s built for engineers, machinists, and hobbyists who need reliable performance in challenging boring tasks as well as general turning.

• Compact geometry for tight bores: The 6.1 mm minimum diameter, 30 mm reach, and R0.2 nose enable precise entry and controlled cutting in confined cavities, improving hole quality and reducing secondary finishing steps.
• Advanced BMK coating for long tool life: Sub-micron BMK-grade carbide with an advanced PVD triple coating delivers exceptional heat resistance and smooth cutting, extending tool life even during demanding operations across a wide material range.
• Versatile, general-purpose performance: Optimized for boring and capable of handling general turning on many materials, making it a reliable, all-around solution for mixed workloads without frequent tool changes.

This tiny carbide bar combines precise geometry with resilient coatings to help you finish small-diameter work with consistent tolerances and a smooth surface finish. The BMK-grade construction supports higher productivity by resisting heat buildup and wear, while its compact size and left-hand orientation give you flexibility in setup and workflow. Whether you’re machining tight bores or performing routine turning jobs, this Carmex tool is designed to deliver dependable performance and repeatable results.
