The Carmex Carbide Tiny Tool is a solid carbide boring bar designed for precision work in tight spaces. Ideal for engineers, machinists, hobbyists, and shop-floor technicians, this compact tool delivers consistent, accurate bore finishing and reliable turning performance in a variety of materials.

• Dual coating options for broad material coverage: Choose BXC for low cutting speeds on stainless steels (ISO P30-P50 / K25-K40) with a PVD TiN coating, or select BMK for ultra-high heat resistance and smooth cutting across a wide range of materials, thanks to its advanced PVD triple coating. This gives you optimized performance whether you’re working slowly on hard steels or pursuing faster, heat-tiered operations.
• Small-diameter precision with practical reach: With a 2.1 mm minimum diameter and a 5 mm reach, plus a defined R0.05 corner radius, this tiny boring bar fits into tight bores and maintains accuracy while delivering clean, consistent finishes.
• Premium TNX-grade solid carbide for reliability: Built from high-quality carbide and engineered for durability, this tool minimizes deflection and wear, providing stable cuts and extended tool life in demanding turning and boring tasks.

This compact, versatile boring bar helps you finish tight bores with confidence, improves material compatibility across stainless steels and other alloys, and supports a reliable, repeatable workflow from setup to finish. The combination of precise geometry, robust carbide, and coating options translates to better surface finishes, reduced rework, and longer intervals between tool changes.
