Description

The Carmex Carbide Tiny Tool – Grooving (MGR) is a compact precision cutting tool designed for small groove operations. Crafted from premium-grade carbide, it delivers accurate, repeatable grooves on tiny parts with a clean edge and long tool life.

Designed for engineers, machinists, hobbyists, and fabricators, this tool reaches tight spaces with a minimum diameter of 5.1 mm, a 1 mm groove width, and a 15 mm reach—enabling reliable grooves in miniature components without sacrificing rigidity.

  • Compact, precise geometry: Engineered for tiny grooves with a 5.1 mm minimum diameter, 1 mm groove width, and 15 mm reach, delivering controlled cuts in tight spaces and reducing chatter.
  • Premium K20 carbide construction: Durable, wear‑resistant carbide provides long edge life, helping you run longer between tool changes in demanding micro‑grooving tasks.
  • Broad compatibility with machines and systems: Designed to fit a wide range of setups, simplifying procurement and speeding integration across diverse workshop environments.

By delivering precise grooves on micro‑scale features, this tool helps you achieve consistent results with fewer reworks and less waste. The compact design opens up hard‑to‑reach pockets, while the K20 carbide extends tool life in tough materials. Its broad machine compatibility supports standardized tooling and faster changeovers, boosting overall workflow and reliability across projects.
