Description

Meet the Carmex Carbide Tiny Tool for face grooving. This solid carbide bar is engineered to create precise, rounded grooves with a full-radius profile, instead of straight slots. It’s ideal for small-diameter workpieces where edge strength and sealing surfaces matter, delivering consistent results with a 5 mm minimum diameter and a 1 mm groove width.

Designed for a wide range of users—from engineers and machinists to technicians and hobbyists—the BMK-grade carbide provides durable, wear‑resistant performance across common metals. Its compact geometry and right-hand cutting orientation help you reach tight spaces and maintain smooth surface finishes, even in demanding setups or production runs.

  • Full Radius Face Grooving for Rounded Grooves: Produces a consistent rounded groove profile on the workpiece face, delivering better edge strength and sealing capability compared with straight-groove tools.
  • BMK-Grade Carbide for Durability: Built from high-hardness carbide to resist wear and heat, extending tool life and maintaining precision through multiple jobs and materials.
  • Compact Right-Hand Geometry (5 mm min dia, 1 mm groove): Specifically designed for small-diameter work and tight spaces, with predictable chip flow and repeatable results in both production and maintenance tasks.

This tool helps you achieve reliable, repeatable grooves on compact parts, reducing the need for rework and speeding up setup and run times. With its full-radius design, durable carbide, and precise right-hand geometry, you’ll experience improved workflow consistency and better overall performance across a range of projects.
