The Carmex Carbide Tiny Tool (MDR) is a compact carbide cutting solution designed specifically for small thread relief, chamfering, and grooving tasks. Built for precision on tiny parts, it delivers clean starts, accurate radii, and reliable grooves in tight spaces, with the performance you expect from a premium MDR tool and TNX-grade carbide.

  • Small-diameter precision for tiny features: Engineered to handle thread relief, chamfering, and grooving on miniature parts with controlled cutting action, ensuring accurate starts and smooth finishes.
  • Durable TNX-grade carbide construction: Premium carbide provides exceptional wear resistance and rigidity, delivering long tool life and consistent performance in demanding applications.
  • Compact geometry with exact reach: 6.1 mm minimum diameter, 1.4 mm reach, and an R0.5 radius enable access to tight spaces and repeatable radii for reliable results.

With the Carmex Tiny Tool in your toolkit, you can complete delicate threading, chamfering, and grooving tasks more efficiently and with repeatable quality. The combination of robust carbide, precise geometry, and MDR design helps reduce setup time, extend tool life, and deliver professional finishes on small components across prototypes, repairs, and precision production workflows.
