Description

The Carmex Carbide Tiny Tool is a solid carbide bar engineered specifically for deep face grooving. With a practical footprint of 15 mm minimum diameter, a 3 mm groove width, and a 43 mm groove depth, it enables deep cuts in a single setup for faster, more consistent grooves. This BMK-grade option uses sub-micron carbide and an advanced PVD triple coating to deliver reliable performance across a range of materials.

  • BMK Grade with PVD Triple Coating: Sub-micron carbide with an advanced PVD triple coating provides exceptional heat resistance and a smooth cutting action, helping maintain edge quality and consistent results through demanding grooving tasks.
  • Optimized Deep Face Grooving Geometry: Designed for deep grooves with precise dimensions (15 mm min diameter, 3 mm groove width, 43 mm groove depth), enabling efficient material removal and fewer passes for faster cycles.
  • General-Purpose, Reliable Performance: Built for versatility across materials, offering dependable cutting performance and long tool life in a wide range of grooving applications.

This tool supports smoother workflows by delivering stable cuts, reducing setup time, and producing repeatable, high-quality grooves. Whether you’re optimizing production runs or tackling precision grooves in varied materials, the Carmex Carbide Tiny Tool provides a confident, consistent result every time.
