The Carmex Carbide Tiny Tool – Face Grooving bar is a solid carbide tool engineered specifically for face grooving, delivering straight, true grooves with clean finishes on stainless steels and a wide range of materials. With a 5 mm minimum diameter and a 1.5 mm groove width, this tool is designed for compact setups and tight tolerances, making it a reliable choice for both production and prototype work. Crafted in the Tiny Tools family and offered in MFR K20 Grade, it combines precision geometry with coatings that enhance performance across speeds and materials.

  • Face-grooving optimized carbide geometry: Produces straight, uniform grooves with consistent width, reducing post-cut finishing and ensuring repeatable results on stainless steel and other alloys.
  • Coatings engineered for durability at low speeds (BXC TiN): TiN-coated grade minimizes wear at low cutting speeds, extending tool life and delivering stable, clean cuts during longer runs.
  • High-heat ready BMK coating for demanding materials: Sub-micron grade with advanced PVD triple coating offers exceptional heat resistance and smooth cutting, enabling reliable performance across a broad material range.

This tool helps streamline groove work by combining a purpose-built geometry with durable coatings that resist wear and heat. The result is consistent groove quality, reduced downtime from tool changes, and reliable performance from setup to finish across materials, including stainless steels. With its precise dimensions and trusted Tiny Tools construction, it’s ready for both demanding fabrication jobs and everyday shop tasks alike.
