The Carmex Carbide Tiny Tool Boring Bar is a compact, solid carbide solution designed for precise small-diameter bores and dependable general turning. With a 4.1 mm minimum diameter, a 15 mm reach, and left-hand cutting geometry, it’s built to perform in confined spaces while delivering consistent depth control and clean finishes.

This tool line offers two coating grades to match your material and speed needs: the BXC grade, a PVD TiN-coated option optimized for lower cutting speeds and broad stainless-steel compatibility (ISO P30-P50 / K25-K40), and the BMK grade, a sub-micron, triple-coated solution (ISO K10-K20) delivering exceptional heat resistance and smooth cutting across a wide range of materials. This versatility makes it suitable for both specialized boring work and general-purpose turning.

• Two advanced coating grades for versatility: Choose BXC TiN for dependable performance at low speeds on stainless steels, or BMK’s sub-micron, triple PVD coating for maximum heat resistance and smooth, consistent cutting across many materials.
• Compact size with long reach for tight bores: 4.1 mm minimum diameter and 15 mm reach let you access confined pockets while maintaining stable engagement and precise depth control in boring and light turning tasks.
• Durable carbide construction for reliable performance: Solid carbide construction plus engineered coatings support long tool life, smoother cuts, and consistent finishes—ideal for demanding applications across materials including stainless.

Designed to streamline machining workflows, the Carmex Tiny Tool delivers reliable, repeatable results with minimal setup and tool changes. Its combination of compact geometry, coating versatility, and robust carbide construction helps you achieve higher-quality bores, faster cycle times, and improved overall productivity in both professional shops and DIY setups.
