The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precision in tight bores and restricted work areas. It’s ideal for engineers, machinists, and hobbyists who need reliable boring and light turning in small spaces, delivering repeatable diameters and clean finishes.

Designed for versatility, this tool features a 5.1 mm minimum diameter, a 22 mm reach, and a precise R0.1 nose. It belongs to Carmex’s family of solid carbide bars and is offered in performance grades that optimize wear resistance and heat handling for a wide range of materials, including stainless steels.

• Ultra-compact boring geometry: The 5.1 mm minimum diameter, 22 mm reach, and R0.1 nose enable precise bore sizing in tight cavities with stable cutting and a clean finish.
• TiN-coated BXC grade for stainless steel: PVD TiN coating improves wear resistance at low cutting speeds, helping extend tool life when machining common stainless steels (ISO P30–P50 / K25–K40).
• BMK grade for high heat and versatility: Sub-micron BMK grade with advanced triple coating delivers exceptional heat resistance and smooth cutting across a broad range of materials.

With its tiny form factor and coated carbide technology, the Carmex Tiny Tool helps you complete boring and small-turning tasks faster and more consistently. The combination of compact geometry and durable coatings reduces setup time, minimizes tool changes, and delivers repeatable diameters and surface finishes across stainless steels and other materials. Built to handle demanding applications while maintaining a smooth cutting action, it supports your workflow from prototype through production with reliable performance.
