The Carmex Carbide Tiny Tool is a dedicated profiling and boring cutter built for precision in tight spaces. Featuring a 5.1 mm minimum diameter, a 3.2 mm reach, and a nose radius of R0.8, this compact tool is designed to access small cavities and complex geometries with consistent results. Its advanced chip breaker and internal coolant bore work together to manage chips and heat, helping you maintain steady cuts and clean finishes.
- Efficient chip control and evacuation: An advanced chip breaker paired with an internal coolant bore reduces chip curling and chip buildup, keeping the cut clear and minimizing downtime.
- Optimized for profiling and boring in tight spaces: The small diameter, short reach, and precise R0.8 nose radius enable accurate profiling and smooth transitions in challenging features and deep pockets.
- Durable TNX-grade carbide for reliable performance: Built to withstand demanding materials like stainless steels and super alloys, delivering long tool life and consistent results under tough cutting conditions.
This tool is designed to improve workflow by delivering predictable, high-quality finishes on difficult materials. The combination of precise geometry, robust carbide, and efficient chip management helps reduce cycle times, minimizes tool wear, and supports repeatable results across production runs.
