Carmex Carbide Tiny Tool is a compact, solid carbide grooving tool engineered for precise full-radius grooves in tight spaces. With a 7.1 mm minimum diameter, a 2 mm groove width, and a 22 mm reach, it delivers consistent groove geometry on small-diameter parts while remaining versatile enough for general turning tasks.

This tool family offers two optimized coatings to match different cutting conditions: BXC, a PVD TiN-coated grade designed for low cutting speeds and excellent performance on stainless steels, and BMK, a sub-micron grade with an advanced PVD triple coating that provides outstanding heat resistance and smooth cutting across a broad range of materials.

  • Full-radius grooving precision: Engineered to produce accurate, repeatable full-radius grooves up to 2 mm wide, with a 22 mm reach for access in restricted areas and compatibility with general turning operations.
  • BMK grade for high-heat performance: Sub-micron carbide with triple PVD coating delivers exceptional heat resistance and smooth cutting, extending tool life and maintaining consistent finishes on demanding materials.
  • BXC TiN-coated option for stainless and low speeds: TiN coating reduces friction at low cutting speeds and excels with a wide range of stainless steels (ISO P30-P50 / K25-K40) for reliable, predictable results.

Designed to fit into busy machining workflows, the Carmex Tiny Tool helps you complete precise grooving tasks quickly while preserving part quality. The dual-grade coating options let you tailor performance to the material and speed you’re working with, reducing tool changes and boosting overall productivity on both small-diameter grooves and general turning projects.
