Cutting tools are our home turf — Crystallume PVD was born from RobbJack, a premium cutting-tool maker. The right coating, matched to your workpiece material and operation, can dramatically extend tool life, raise cutting speeds, and hold tolerance. Here is how each coating in the line maps to the job.
Built for the requirements that matter.
Every coating below is matched to the realities of cutting tools & tooling — and applied on modern equipment, with your parts handled with documented care.
Key requirements
- Long tool life & edge retention
- Hot hardness for high-speed cuts
- Low friction & anti-built-up-edge
- The right coating for each workpiece material

In our customers' words.
“RobbJack’s Die Mold cutters have been a game changer for us. We are cutting 52 HRc material, and the AlTiN coating keeps the tools running far longer than anything else we have tried. The performance is incredible, and our cutting tool costs have been reduced by over 500%.”
