The Carmex Carbide Tiny Tool is a precision boring bar designed for micro-machining, with a solid carbide construction that excels at tight bores while also handling general turning tasks. Its compact geometry fits into small workpieces, delivering accurate holes and clean finishes in hard metals and tricky materials. The tool is specified for a 1.2 mm minimum diameter and a 7 mm reach, with an R0 nose for maximum precision in miniature work.

To match a range of materials and turning demands, this tool family offers two optimized carbide grades with protective coatings. The BXC grade features a PVD TiN coating optimized for low cutting speeds and excellent wear resistance on stainless steels (ISO P30-P50 / K25-K40). The BMK grade uses a sub-micron, triple-coated PVD process that delivers outstanding heat resistance and smooth cutting, making it a versatile choice for many materials. Together, they provide dependable performance from delicate micro-habits to more demanding turning tasks.

• Tiny-diameter bore capability: 1.2 mm minimum diameter with 7 mm reach and an R0 nose enable precise bores and tight features in small parts, electronics housings, and precision fixtures.
• Coated grades for versatile wear and heat resistance: BXC TiN coating suits stainless steels at low speeds for wear resistance, while BMK’s sub-micron, triple PVD coating delivers high heat resistance and smooth cutting across a broad material range.
• Solid carbide durability and reliable performance: Built from solid carbide for rigidity and long tool life, providing consistent results for boring and general turning with minimal downtime.

Designed to integrate smoothly into professional workflows, this tiny tool helps you achieve consistent hole quality, reduces tool changes, and supports repeatable results across materials. Its rigid construction and advanced coatings protect cutting edges, maintain precision over multiple passes, and deliver dependable performance in micro-bore and precision turning applications—making it a trusted choice for engineers, machinists, and hobbyists alike.
