Description

The Carmex Carbide Tiny Tool - Grooving (MGL) is a precision cutting tool designed for small grooving applications. Made from premium carbide, it delivers clean, accurate grooves on tiny parts and components, even in tight spaces.

With a 23 mm reach (Left Hand), a minimum diameter of 6.1 mm and a groove width of 0.79 mm, this tool is optimized for left-hand grooving on compact parts. It offers broad machine compatibility, making it a versatile addition to shops that run milling, turning, or CNC setups.

  • Ultra-precise small-groove capability: Cuts narrow grooves with a minimum diameter of 6.1 mm and groove width of 0.79 mm, delivering repeatable, clean grooves on small parts.
  • Durable carbide for long tool life: Premium K20 grade carbide provides hardness and wear resistance that help maintain sharpness and reduce tool changes over production runs.
  • Versatile reach and left-hand design: 23 mm reach with left-hand orientation enables stable cutting in tight features and broad compatibility with a wide range of machines and setups.

This tiny grooving tool supports efficient workflows by enabling precise grooves on compact components in fewer passes, reducing cycle times and rework. The durable carbide and proven geometry deliver consistent results across batches, while the broad machine compatibility ensures smooth integration into your existing manufacturing or prototyping processes.
