The Carmex Carbide Tiny Tool Boring Bar is a compact, solid carbide tool designed for precision internal boring and small-diameter turning. With a 6.1 mm minimum diameter and a 22 mm reach, it helps you access tight bores and deep features without swapping in larger tooling.

This bar is offered in BXC Grade, featuring a PVD TiN coating optimized for low cutting speeds. It delivers reliable performance on a wide range of stainless steels (ISO P30-P50 / K25-K40), helping you achieve consistent cuts at slower speeds while extending edge life.

• Compact bore-capable geometry: 6.1 mm minimum diameter and 22 mm reach let you access tight bores and reach deep features without frequent tool changes.
• PVD TiN-coated BXC Grade for low-speed cutting: Optimized for stainless steels, providing stable cuts and predictable performance at reduced cutting speeds.
• R0.05 radius for smooth finishes: A precise edge radius that supports clean, controlled cuts and improved surface finish in boring and turning applications.

Designed for both dedicated boring tasks and general turning, this tiny carbide bar helps you complete small-diameter work with fewer tool changes, reliable results, and consistent finishes across materials.
