Description

The Carmex Carbide Tiny Tool - Profiling & Boring 47° - MQR is a precision cutting tool designed for small profiling and boring applications. This tiny tool is built from premium K20 carbide, delivering exceptional durability, wear resistance, and long tool life. It’s optimized for intricate shapes on small parts, making it ideal for engineers, machinists, and hobbyists who need predictable, repeatable results. With a minimum diameter of 8.1 mm, a reach of 27 mm, and a 0.2 mm corner radius, the 47° MQR geometry enables accurate profiling and clean transitions even in tight pockets.

  • 47° MQR Profiling Geometry: Provides precise profiling and accurate edge definition on small features, delivering repeatable results with minimal tool deflection.
  • 27 mm Reach in a Compact Tool: Access deep or recessed features without repositioning the part or changing tooling, boosting productivity and reducing setup time.
  • Premium K20 Carbide with R0.2 Corner Radius: Combines high hardness and wear resistance with a small, controlled corner radius for smooth finishes and extended tool life.

Designed to improve workflow on micro-machining projects, the Carmex Tiny Tool helps you achieve tight tolerances, crisp edges, and consistent finishes across batches. Its durable carbide and optimized geometry reduce downtime from tool wear and rework, giving you confidence to tackle delicate profiling and precise bores in demanding materials.
