Description

The Carmex Carbide Tiny Tool (MDL) is a compact carbide cutting tool designed for small thread relief, chamfering, and grooving on miniature parts. With a 6.1 mm minimum diameter, 1.4 mm reach, and a left-hand R0.5 edge, it’s built for tight-access work and precise starts in threading and chamfering tasks.

Made from premium-grade carbide, it delivers consistent cutting performance, excellent wear resistance, and long tool life, so you can rely on predictable results in demanding production and prototyping work.

  • Tiny-diameter design for tight spaces: Enables accurate thread relief, chamfering and grooving on very small parts where larger tools can't reach, helping you complete assemblies faster with fewer setups.
  • Premium carbide for long life and wear resistance: The carbide alloy provides edge retention and durability under demanding cutting conditions, reducing tool changes and downtime.
  • MDL geometry for integrated thread relief, chamfering & grooving: Optimizes cutting action to deliver clean starts, consistent depths, and smooth finishes across multiple operations in a single setup.

This tiny tool helps you tackle delicate threading and chamfering on small components with confidence, improving workflow by enabling quicker setups and more predictable results. Its durable carbide and precisely engineered geometry minimize wear and tool changes, while the left-handed R0.5 edge supports common left-hand thread tasks for reliable, repeatable performance across jobs.
