Designed for engineers, machinists, and hobbyists alike, this tool handles small-grooving tasks on micro components, electronics housings, and precision parts with ease. The 5.1 mm diameter, 0.79 mm groove width, and 22 mm reach keep operations tight and controlled, while the BMK-grade carbide ensures long tool life and reliable performance through repeated cuts. It is compatible with a wide range of machines and systems, simplifying setup and helping you move from job to job with confidence.

  • Tiny, precise grooving geometry: Enables accurate grooves on small parts with strict width and depth control, including a 0.79 mm groove width and 22 mm reach for tight spaces.
