The Carmex Carbide Tiny Tool is a precision boring bar crafted from solid carbide. Its compact 2.5 mm minimum diameter, 10 mm reach, and nose radius of R0.1 make it ideal for small-bore work, tight cavities, and delicate turning tasks. While designed primarily for boring applications, it also handles general turning, giving you a single tool that adapts to multiple jobs in a single setup.

Designed for versatility, this tool uses coating grades that optimize performance across materials. The BXC TiN coating supports low cutting speeds and pairs well with a wide range of stainless steels (ISO P30-P50 / K25-K40). The BMK grade features a sub-micron composition with advanced PVD triple coating, delivering extremely high heat resistance and smooth cutting for maximum performance across all materials (ISO K10-K20).

• Coating options for versatility and reliability: Choose BXC TiN for efficient cutting at low speeds with stainless steels, or BMK’s triple-coated, high-heat-resistant design for tougher materials and smoother finishes.
• Compact, precise boring capability: With a 2.5 mm minimum diameter and 10 mm reach, this tiny tool reaches tight bores and deep features while maintaining stable, accurate cuts.
• Durable carbide for general turning: Solid carbide construction provides rigidity and wear resistance, offering reliable boring and capable turning across a wide range of materials.

This tool is built to deliver consistent results, reduce setup time, and help you complete small-diameter boring tasks with confidence. Its robust design supports long runs between tool changes, making it a dependable choice for professional shops and serious hobbyists alike.
