The Carmex Carbide Tiny Tool (MPR) is a precision boring and profiling tool designed for small-feature work. Its compact geometry makes it ideal for engineers, machinists, hobbyists, and technicians who need to shape intricate profiles or bore precise holes in tiny parts.

Made from premium-grade carbide, this tiny tool combines durability with exceptional cutting performance. With a 3.1 mm minimum diameter, 10 mm reach, and an R0.05 radius, it delivers accurate, clean cuts in tight spaces and delicate components.

  • Ultra-compact size with extended reach: The 3.1 mm minimum diameter and 10 mm reach enable access to tight pockets and complex profiles without sacrificing rigidity, delivering consistent profiling and boring in small parts.
  • Premium K20 carbide for long tool life: Crafted from high-quality carbide (K20 grade), this tool resists wear and maintains sharpness for reliable performance across multiple passes in demanding applications.
  • Finely tuned profile radius (R0.05) for smooth finishes: The precise edge geometry with an R0.05 radius produces clean transitions and accurate shapes, reducing post-process refinishing and delivering a smooth surface finish.

Whether you're working with small mechanical components, prototype assemblies, or delicate profiles, this Carmex Tiny Tool helps you achieve precise results with confidence. Its durability and precise geometry support consistent outcomes, minimize rework, and improve overall efficiency on your smallest parts from first pass to final finish.
