The ones our customers buy most.Description
The Carmex Carbide Tiny Tool is a profiling and boring cutter built for precision in tight spaces and on challenging materials. Its advanced chip breaker paired with an internal coolant bore delivers efficient chip evacuation, helping maintain a clear cutting zone and steady performance—ideal for stainless steels, super alloys, and other materials that tend to form curly or stringy chips. The tool features a 4.1 mm minimum diameter, 1.2 mm reach, and left-hand R0.4 geometry in TNX grade for reliable, repeatable results.
- Advanced chip control with an internal coolant bore: The chip breaker design works with internal coolant to evacuate chips quickly, reducing heat and re-cutting so you can maintain steady cuts and longer tool life even with difficult materials.
- Optimized for profiling and boring in hard-to-machine materials: Specifically engineered to handle stainless steels, super alloys, and other curly-chip materials, delivering stable entry, consistent diameters, and predictable finishes.
- Compact left-hand TNX-grade carbide with precise geometry: A small-diameter tool designed for tight pockets and long reach scenarios, offering enhanced wear resistance and reliable performance across repeated jobs.
With this tool, you gain more predictable cycle times, fewer tool changes, and cleaner surface finishes. The combination of a compact form factor, efficient chip evacuation, and the wear-resistant TNX-grade carbide helps you achieve reliable results across multiple profiling and boring tasks, reducing downtime and improving overall productivity.
