The Carmex Carbide Tiny Tool – Boring & Profiling (MPL) is a precision cutting instrument designed for small profiling and boring tasks. Crafted from premium-grade carbide, it delivers consistent performance and durable edge life in tight spaces, making intricate profiles on tiny parts and components easier than ever.
This tool is built for engineers, machinists, tradespeople, hobbyists, and anyone needing accurate micro-machining results. Its compact form, combined with a specialized geometry, supports precise profiling and bore operations in confined areas with minimal tool changes.
- Ultra-compact profiling reach: The 4.1 mm minimum diameter and 15 mm reach enable access to tight pockets and complex profiles without repositioning, boosting efficiency on small parts.
- Premium TNX-grade carbide: Exceptionally hard and wear resistant, this substrate delivers long tool life and reliable performance in demanding materials, reducing downtime and replacements.
- Left-hand nose radius (R0.1): Left-hand configuration with a fine R0.1 nose radius provides smooth, consistent cuts and precise profiling for delicate finish surfaces in tight bore work.
Designed to integrate smoothly into existing setups, the Carmex Tiny Tool helps you complete micro-machining tasks with confidence. Its durable carbide edge, compact reach, and refined nose geometry translate to repeatable results, less rework, and cleaner finishes on small parts and assemblies.
