The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precision internal work and light turning tasks. With a 1.2 mm minimum bore size, a 7 mm reach, and a left-hand R0 geometry, it delivers consistent results in tight spaces. This tool is ideal for engineers, machinists, hobbyists, and shops that value reliable performance in confined bores.

Available in two high-performance carbide grades, the tool line covers a wide range of materials and speeds. BXC is a PVD TiN-coated grade optimized for low cutting speeds and stainless steels (ISO P30-P50 / K25-K40), while BMK is a sub-micron grade with a triple PVD coating that provides maximum heat resistance and smooth cutting for general-purpose turning (ISO K10-K20).

• Tiny-diameter bore capability: Delivers precise holes at 1.2 mm minimum diameter, helping maintain tight tolerances and reduce finishing ops.
• 7 mm reach for deep internal work: Lets you access deeper features without repositioning, improving throughput and reducing setup time.
• Two high-performance carbide grades: Choose BXC TiN-coated grade for low-speed cutting in stainless steel (ISO P30-P40 range) or BMK sub-micron grade with triple coating for maximum heat resistance and smooth cutting across a broad range of materials.

By combining small-diameter capability, extended reach, and tailored coating grades, the Carmex Tiny Tool supports precise bore quality, faster setups, and reliable performance across stainless steels and other materials. Its left-hand orientation and robust carbide construction help maintain consistent finishes and reduce downtime in both prototyping and production environments.
