Description

The Carmex Carbide Tiny Tool is a precision boring and profiling tool designed for small features and tight spaces. It’s ideal for engineers, machinists, technicians, and hobbyists who need accurate profiles and clean bores in miniature parts and components. Crafted from premium carbide, this tool pairs sharp cutting edges with dependable durability for repeatable results in demanding tasks.

  • Ultra-precise profiling and boring in tight spaces: Delivers accurate geometry and smooth edges on small parts, enabling intricate shapes and precise bore work where room is limited.
  • Premium carbide for long-lasting performance: Built from high-grade carbide to resist wear and chipping, delivering consistent cuts across multiple jobs and materials.
  • Compact, versatile geometry for hard-to-reach features: With 5.1 mm diameter, 22 mm reach, and a 0.2 mm nose radius, it accesses confined pockets and tight cavities without compromising finish or control.

This Tiny Tool helps streamline workflows by reducing the need for multiple tools in tiny-profile projects. Its durable construction and precise geometry translate to fewer tool changes, less deburring, and reliably repeatable results, making it a dependable choice for both professional shops and serious hobbyists working on compact components.
