The Carmex Carbide Tiny Tool – Boring Bar is a compact, solid carbide tool designed for internal boring in tight spaces and light turning tasks. It features an 8.1 mm minimum diameter, 22 mm reach, and a left-hand orientation with an R0.2 corner radius to deliver precise, predictable cuts in confined bores. Available with BXC TiN-coated and BMK triple-coated grades, it offers optimized performance for stainless steels at low speeds and high-heat resistance across materials.
- Compact size with long reach: 8.1 mm minimum diameter and 22 mm reach let you access deep, narrow bores while maintaining rigidity and accuracy. The R0.2 corner radius and left-hand geometry help produce clean, consistent finishes in challenging internals.
- Two coating grades for optimized performance: BXC TiN-coated grade is ideal for low-speed cutting of stainless steels (ISO P30-P50 / K25-K40), reducing wear and extending tool life. BMK sub-micron grade with a triple PVD coating offers excellent heat resistance and smooth cutting across a broad material range (ISO K10-K20).
- Versatile boring bar for turning tasks: While designed for boring, this solid carbide bar handles general turning work as well, enabling a single tool to cover multiple operations and reduce tool changes in mixed workflows.
With the Carmex Tiny Tool, you gain precise control in tight bores, longer tool life through advanced coatings, and versatility that speeds up setups and improves overall workflow. The robust carbide construction combined with optimized geometry helps you achieve consistent finishes across stainless steels and other materials, whether you’re prototyping or running production jobs.
