Carmex Carbide Tiny Tool is a compact profiling and boring cutter designed for precision work in tight spaces. With a 4.1 mm minimum diameter and 0.2 mm reach, it’s ideal for small features, shallow bores, and finishing passes where accuracy matters. The internal coolant bore and advanced chip breaker help manage chips and heat, so you can rely on clean cuts in challenging applications.
- Small-diameter profiling and boring: Optimized for tight bores and fine profiles, enabling precise results in compact workpieces.
- Advanced chip control with internal coolant bore: Helps evacuate chips quickly and keeps the cutting edge cooler for consistent finishes and reduced downtime.
- Left-hand geometry with R0.4 corner radius: Designed for left-hand setups with a controlled corner radius to deliver smooth entry/exit and reliable performance on demanding materials.
Designed for stainless steels, super alloys, and other materials that tend to produce curly chips, this tool combines durability with practical usability. The TNX Grade carbide and sharpened geometry provide long tool life and consistent results, so you can complete profiling and boring tasks with confidence and efficiency from setup through finish.
