The Carmex Carbide Tiny Tool Boring Bar is a compact, solid carbide tool designed for precise small-diameter boring and versatile turning. It features a 7.1 mm minimum diameter, a 22 mm reach, left-hand orientation, and an R0.2 nose radius to fit into tight bores and finish-ready holes.

• PVD TiN coating for low-speed stainless cutting: The BXC grade uses a titanium nitride coating that reduces wear and friction at low cutting speeds, delivering longer tool life and stable hole quality on stainless steels in ISO P30-P50 / K25-K40 ranges.
• Small-diameter geometry for tight bores: With a 7.1 mm minimum diameter and 22 mm reach, plus a precise R0.2 nose, it achieves accurate holes in confined spaces while remaining suitable for general turning jobs.
• Left-hand orientation with R0.2 nose for stable cutting: The tool’s geometry supports consistent edge geometry and chip control, helping reduce chatter and produce repeatable finishes on a variety of workpieces.

This tiny carbide tool helps you complete small-hole projects faster with fewer setups, delivering consistent hole geometry and smooth finishes across common stainless steels. The combination of the TiN coating and compact, purpose-built geometry provides reliable performance for daily production, repairs, and prototype work.
