The Carmex Carbide Tiny Tool is a precision profiling and boring cutter designed for tight spaces and exact contours. It’s ideal for engineers, machinists, and hobbyists who need reliable small-diameter profiling in limited envelopes.
Designed with TNX Grade carbide and a compact form factor, it delivers consistent profiles with robust chip control. The tool features a 4.1 mm minimum diameter, 1.2 mm reach, and a nose radius of R0.4, plus an advanced chip breaker and an internal coolant bore to promote efficient chip evacuation when machining stainless steels, super alloys, and other tough materials that tend to produce curly chips.
- Advanced chip breaker with internal coolant bore: The combination keeps chips under control and evacuates them quickly, reducing heat buildup and improving surface finish on difficult materials.
- Compact profiling and boring capability: 4.1 mm minimum diameter, 1.2 mm reach, and R0.4 nose enable precise profiling and shallow bores in tight pockets with consistent, accurate contours.
- TNX Grade carbide for wear resistance: Delivers long tool life and reliable performance in demanding materials, minimizing tool changes and downtime.
This tiny tool helps you complete challenging profiling and boring tasks with confidence, delivering clean finishes in hard-to-machine metals while promoting efficient chip control and dependable durability across jobs. It supports repeatable results, reduces rework, and keeps your workflow moving smoothly in both production and precision environments.
