The Carmex Carbide Tiny Tool is a precision boring bar crafted from solid carbide, designed for small-diameter bore work and capable of handling general turning tasks. With a 1 mm minimum diameter, 4 mm reach, and a precise R0.05 nose radius, it delivers tight tolerances and clean hole quality in confined spaces.

This tool is offered in two high-performance coating options to match your material and speed requirements. The BXC grade features a PVD TiN coating optimized for lower cutting speeds and excellent compatibility with stainless steels (ISO P30-P50 / K25-K40). The BMK grade uses a sub-micron core with an advanced triple PVD coating for exceptional heat resistance and smoother cutting across a broad range of materials. Together, they provide reliable performance in demanding machining scenarios.

• Ultra-compact size for tight bores: A 1 mm minimum diameter and 4 mm reach enable precise, controlled cutting in small-diameter cavities and short overhangs, improving hole accuracy and surface finish.
• Two high-performance coatings for versatile materials: Choose BXC TiN for steady results at lower speeds on stainless steels, or BMK’s triple PVD coating for high-heat, high-performance cutting across a wider material set.
• Durable carbide with heat-ready coatings: Solid carbide core delivers stiffness and wear resistance, while advanced coatings reduce wear and thermal distortion for longer tool life and fewer tool changes.

Designed for engineers, makers, and professionals who demand consistent, predictable results, this tiny boring bar helps streamline setups, improve throughput, and deliver reliable outcomes across applications—from precision bore work to everyday turning tasks.
