Description

The Carmex Carbide Tiny Tool - Grooving - MGL is a precision cutting tool designed specifically for small grooving tasks. Its compact form and specialized geometry enable accurate, repeatable grooves on tiny parts and components, making micro-machining straightforward and reliable. Built for engineers, machinists, hobbyists, and technicians alike, this tool delivers clean results in tight spaces without sacrificing ease of use.

Made from premium carbide (K20 grade), it combines hardness, strength, and exceptional wear resistance for long tool life and dependable performance across a range of materials. With a minimum groove diameter of 7.1 mm, a groove width of 1.59 mm, and a reach of 30 mm in a left-hand configuration, it remains compatible with a wide array of machines and setups, simplifying integration into existing workflows.

  • Micro-scale grooving geometry: engineered to produce precise grooves on small diameters (as small as 7.1 mm) with a 1.59 mm width, enabling accurate, repeatable cuts in tight spaces.
  • Premium carbide construction: built with K20 grade carbide for outstanding wear resistance and long tool life, reducing downtime and maintaining consistent performance.
  • Left-hand design with 30 mm reach: optimized for left-hand cutting with a 30 mm reach, providing improved access and balance when machining deep or challenging grooves on compact parts.

This tiny grooving tool helps you streamline micro-machining workflows by delivering clean, reliable grooves with minimal setup. Its durability and broad machine compatibility translate to fewer tool changes and more consistent results across batches, making it a dependable choice for precision groove work in automotive, electronics, and small-mechanics applications.
