Carmex Carbide Tiny Tool - Boring Bar - MTR - BXC Grade - 6.1mm Minimum Diameter x 15mm Reach x R0.2

The Carmex Carbide Tiny Tool is a compact boring bar designed for precision in tight spaces. With a 6.1 mm minimum diameter, a 15 mm reach, and a 0.2 mm nose radius, it delivers controlled material removal in small bores and close-tolerance turning.

This tool family offers two coating grades to match your material and speed needs: BXC—the PVD TiN-coated option optimized for low cutting speeds and stainless steels (ISO P30-P50 / K25-K40)—and BMK, a sub-micron grade with a triple PVD coating for outstanding heat resistance and smooth cutting across a wide range of materials (ISO K10-K20).

• Compact, precise boring capability: Access tight bores and hard-to-reach areas with confidence, thanks to the small diameter and 15 mm reach that keep tolerances tight and finishes clean.
• Coated for longevity in stainless steel: BXC TiN coating reduces friction and wear at low speeds, helping the tool last longer on stainless alloys.
• High-heat versatility for all materials: BMK grade delivers excellent heat resistance and smooth cutting across many materials, reducing downtime and improving consistency.

Whether you’re a shop engineer, a foreman, or a hobbyist, this tiny tool helps you complete small-bore projects with repeatable results, quicker setups, and fewer tool changes. Choose BXC for stainless steel tasks at lower speeds or BMK when you’re cutting multiple materials or pushing the tool to higher temperatures—either way, you’ll enjoy dependable performance and predictable outcomes.
