The Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide cutting tool designed for internal boring and precise small-diameter turning. With a minimum diameter of 1.5 mm and a 10 mm reach, it lets you access tight bores and intricate features with consistent accuracy, even in limited-space setups. This left-hand tool is built for reliability in demanding manufacturing environments.

Available in two high-performance carbide grades, it adapts to your material and speed requirements. The BXC grade features a PVD TiN coating for low cutting speeds and excels with stainless steels (ISO P30-P50 / K25-K40), delivering controlled wear and dependable finishes. The BMK grade uses a sub-micron structure with advanced PVD triple coating (ISO K10-K20), offering exceptional heat resistance and smooth cutting across a broad range of materials. These options provide tailored performance without changing your setup.

• Two advanced carbide grades for versatile material compatibility: Choose BXC for stainless steels at low speeds or BMK for broad-material use with high heat resistance and smooth cutting, giving you predictable results across different jobs.
• Miniature geometry for tight bores: 1.5 mm minimum diameter, 10 mm reach, and a precise R0.1 nose radius enable accurate, repeatable bore finishes in confined spaces.
• Left-hand orientation for straightforward setup: Designed for left-hand cutting applications, helping maintain stable chip flow and consistent results within standard tooling configurations.

This tiny carbide boring bar helps you streamline workflows by delivering precise bores, extended tool life, and reliable performance across common materials. Its specialized coatings and compact geometry reduce wear and chatter, improve surface finish, and minimize downtime, so you can finish parts faster with confidence.
