The Carmex Carbide Tiny Tool is a solid carbide boring bar designed for precision in small-diameter work and general turning. With a 2.1 mm minimum diameter and a 10 mm reach, it lets you access tight bores and confined spaces without sacrificing rigidity.

This tool line features two coating options to optimize your process: BXC TiN-coated grade for low cutting speeds, delivering solid performance with a wide range of stainless steels (ISO P30-P50 / K25-K40); and BMK-grade bars, a sub-micron grade with an advanced PVD triple coating (ISO K10-K20) that delivers extremely high heat resistance and smooth cutting for general-purpose use across all materials.

• Ultra-compact geometry for tight bores: 2.1 mm minimum diameter and 10 mm reach enable precise boring in confined spaces, reducing the need for multiple tools.
• Coating options for improved performance: BXC TiN supports low cutting speeds and stainless steels, while BMK’s sub-micron grade with triple PVD coating provides high heat resistance and smooth cutting across a broad material range.
• R0 edge geometry for clean, consistent finishes: Designed to deliver stable cuts and clean bore walls, helping extend edge life and reduce finishing passes.

By combining compact size with coating-enhanced durability, this tool improves workflow for micro-bore projects and everyday small-diameter turning. It delivers consistent finishes, reduces downtime due to wear, and supports reliable first-pass results across a broad range of materials, including stainless steels. The dual BMK/BXC coating options give you the flexibility to match cutting speed and material, so you can choose the right tool for the job and keep production moving smoothly.
