Description
The Carmex Carbide Tiny Tool is a precision profiling and boring tool designed for small parts and intricate shapes. With a 47° profiling geometry, it delivers accurate contours and clean finishes in tight spaces, making it ideal for engineers, machinists, hobbyists, and fabricators tackling miniature components. Built from premium-grade carbide in the TNX grade, this tiny tool combines stiffness and wear resistance you can rely on across a range of materials.
The compact size is paired with an 8.1 mm minimum diameter and 27 mm reach, plus an R0.2 corner radius, enabling access to deep pockets and tight profiles while maintaining rigidity and control.
- 47° profiling geometry for intricate shapes: Enables precise contouring and smooth surfaces on small features, reducing the need for additional finishing passes.
- Premium TNX-grade carbide for durability: Delivers long tool life and consistent edge stability, even in demanding profiling and boring tasks.
- Compact size with deep reach: 8.1 mm minimum diameter, 27 mm reach, and an R0.2 corner radius provide access to tight pockets and sharp corners without sacrificing rigidity.
Designed to deliver consistent, high-quality results in small-profile work, this tool helps streamline setups, reduce rework, and improve overall workflow. Its combination of precise 47° geometry, durable carbide, and compact reach makes it a reliable choice for production runs, prototype development, and maintenance tasks that require careful profiling and boring in restricted spaces.
