The Carmex Carbide Tiny Tool is a solid carbide bar engineered specifically for face grooving. It creates true rounded grooves with a full-radius profile, helping parts seat securely and reducing the need for additional finishing steps. Designed for a wide range of users—from engineers and machinists to hobbyists—this tool delivers consistent, repeatable results in demanding applications.

Designed for precision in tight spaces, the tool’s compact geometry supports small feature work without sacrificing performance. Its right-hand cutting orientation provides predictable chip flow and reliable results across multiple passes, making it a dependable choice for routine groove machining.

  • Full-radius face grooving profile: Produces true rounded grooves for better mating surfaces, smoother edges, and reduced secondary finishing work.
  • BMK Grade MZR carbide construction: Engineered for wear resistance and long tool life, delivering consistent, repeatable performance on challenging materials.
  • Compact size: 5 mm minimum diameter x 1.5 mm groove width: Enables precise control in tight pockets and small features while maintaining stable cutting and accurate groove width.

This tool helps you complete groove machining with confidence—fewer passes, fewer adjustments, and more predictable outcomes—so you can streamline setups, improve part accuracy, and reduce downtime in your machining workflow.
