Diamond Tooling

Choosing The Right Diamond:

Amorphous Diamond: A PVD amorphous diamond coating which improves lubricity and wear resistance in nonferrous materials. Performance similar to CVD Diamond, but significantly less expensive. Coating is thin relative to CVD diamond preventing edge rounding. Sharp edges improve results (performance and finish) over CVD in certain abrasive, non-ferrous materials (copper, brass, high silicon aluminum). Low temperature threshold makes diamond unsuitable for ferrous applications.

CVD Diamond: True Crystalline CVD diamond is grown directly into a carbide end mill. Dramatically improves hardness. Hardness improves abrasion resistance and extends tool life up to 50x and allows higher feed rates than uncoated carbide. Ideal for machining Graphite, Composites, Green Carbide, and Green Ceramics. Diamond layer approx 5 times thicker than Amorphous Diamond improving wear resistance. Low temperature threshhold makes diamond unsuitable for ferrous applications.

PCD Diamond (Polycrystalline Diamond): PCD diamond is manufactured as a carbide backed flat wafer. The wafer is brazed to a carbide body to form an end mill. PCD has excellent hardness and abrasion resistance. Thickest diamond layer we offer. Sharply ground cutting edges and thick diamond layer combine the sharp edge benefits of Amorphous Diamond with the abrasion resistance of CVD Diamond. Low temperature threshold makes diamond unsuitable for ferrous applications.
