Carmex Carbide Tiny Tool - Boring Bar - MTR - TNX Grade - 3.1mm Minimum Diameter x 15mm Reach x R0.1

The Carmex Carbide Tiny Tool is a solid carbide boring bar designed for precision in tight spaces. With a minimum diameter of 3.1 mm and a reach of 15 mm, it excels at deep bore access while maintaining rigidity. The nose radius is 0.1 mm (R0.1), which supports clean entry and accurate material removal for tight tolerances.

Designed primarily for boring, this tool also handles general turning. It comes in TNX-grade coatings optimized for performance across different materials: BXC is a PVD TiN-coated grade tailored for lower cutting speeds and strong compatibility with stainless steels, while BMK is a sub-micron grade with advanced PVD triple coating that offers high heat resistance and smooth cutting across a broad material range.

• Ultra-compact bore capability: 3.1 mm minimum diameter with a 15 mm reach lets you access tight bores and deep features while preserving tool rigidity for accurate, repeatable results.
• Two TNX-coated grades for versatility: choose BXC TiN for stainless steels at lower speeds or BMK with triple coating for high heat resistance and smoother cuts across many materials, extending tool life and reducing wear.
• R0.1 nose radius for precise finishes: the 0.1 mm nose radius delivers clean entry and refined surface finish on small-diameter bores, helping achieve consistent quality across parts.

This tooling combination supports efficient workflows: fewer tool changes, reliable performance across common materials, and the ability to maintain tight bore tolerances with predictable results. The solid carbide construction, paired with specialized coatings, helps you boost productivity while delivering durable, dependable performance in demanding boring and turning applications.
