Description

The Carmex Carbide Tiny Tool is a compact, solid carbide bar engineered for deep face grooving. Built for machinists, engineers, and hobbyists alike, it delivers precise, reliable grooves in tight spaces. It features a 15 mm minimum diameter, a 3 mm groove width, and a 27 mm groove depth, making it ideal for demanding deep-groove applications where standard tools struggle.

Note: This product line doesn’t contain bars for left-hand operations. The MVR grade uses a K20 carbide structure to provide robust wear resistance and consistent cutting performance across a range of materials, helping you achieve long tool life and dependable results in real-world production.

  • Deep-face grooving geometry for efficient cuts: Designed for deep grooves with a 27 mm depth and 3 mm width, plus a 15 mm minimum diameter, enabling clean, consistent grooves in confined spaces and reducing secondary finishing passes.
  • K20-grade carbide for durability: High-hardness carbide maintains sharpness and resists wear during extended runs, delivering reliable performance and longer tool life on challenging materials.
  • Versatile across materials with smooth cutting: Optimized for demanding grooving tasks while providing smooth cutting action and predictable results across a broad range of materials, helping you keep workflows on schedule.

Choosing the Carmex Carbide Tiny Tool means faster, cleaner groove creation with fewer tool changes and rework. Its dedicated geometry and durable MVR K20 carbide deliver consistent, high-quality results, improving overall productivity and providing confidence from setup to part finish.
