Description

Carmex Carbide Tiny Tool — Face Grooving bars are solid carbide cutting tools designed for precise face grooves. Built in K20-grade with an 8 mm minimum diameter and a 1.5 mm groove width, these Tiny Tools deliver straight, repeatable grooves that simplify setup and downstream finishing. Ideal for engineers, machinists, and fabricators working with stainless steels and a wide range of materials, they’re ready to perform in demanding production environments.

  • Straight-groove geometry for consistent finishes: Specifically engineered for face grooving, these bars produce clean, straight grooves with predictable results, helping you reduce finishing steps and improve part consistency.
  • Coating options tailored for speed and material: BXC with PVD TiN coating enhances wear resistance at low cutting speeds for stainless steels (ISO P30-P50 / K25-K40). BMK offers a sub-micron grade with a triple PVD coating for exceptional heat resistance and smooth cutting across a variety of materials (ISO K10-K20).
  • Durable, versatile carbide designed for all materials: As part of the Tiny Tools family, these bars are built for long life and reliable performance, delivering solid tool life and versatile use across different materials with consistent engagement at the 8 mm diameter/1.5 mm groove width specification.

Whether upgrading a production line, standardizing a face-grooving operation, or tackling challenging stainless steels, these Carmex Tiny Tool bars help you achieve reliable groove geometry, extended tool life, and smoother cutting. The dual coating options let you tailor performance to your material and speed, reducing downtime and improving overall workflow with consistent results.
