Tools by Application

Application Recommended Tool
Carbon fiber / CFRP machining PCD End Mill – Flat / Ball Nose
Aluminum & non-ferrous alloys PCD End Mill – High-Helix
Ceramic & glass-filled composites PCD End Mill – Straight Flute
Graphite & EDM electrodes PCD End Mill – Fine Pitch
PCB & circuit board routing PCD End Mill – Micro / Miniature

Why PCD?

  • Hardness second only to natural diamond — extreme abrasion resistance
  • 10–50× longer tool life vs. carbide in abrasive materials
  • Maintains sharp cutting edge for consistent surface finish
  • Ideal for dry or minimum-quantity lubrication (MQL) machining

Frequently Asked Questions

Q: What materials can PCD end mills cut?
A: PCD end mills excel in non-ferrous and abrasive materials — carbon fiber (CFRP), fiberglass (GFRP), aluminum, copper, graphite, ceramics, and plastics. They are not suitable for ferrous metals (steel, iron) due to carbon diffusion at high temperatures.

Q: How does PCD compare to carbide end mills?
A: PCD offers significantly higher hardness and wear resistance, resulting in longer tool life and better surface finish in abrasive materials. Carbide is more versatile across material types; PCD is the premium choice for high-volume or precision work in composites and non-ferrous metals.

Q: What is the recommended cutting speed for PCD end mills?
A: PCD end mills typically run at higher surface speeds than carbide — 300–1000 m/min depending on material. Use dry cutting or MQL; avoid coolant flooding on some ceramics. Consult the specific product datasheet for parameters.
