Crystallume, known for its chemical vapor deposition (CVD) diamond technology, features its three diamond-coated tool lines — Standard Premium, Lightning and Stealth — for machining the thinnest details in graphite electrodes. 

The company’s newest and thinnest diamond coating, Stealth, is only 2-3 µm thick, ensuring that tools with the coating have the sharpest solid diamond cutting edge available, according to the company. Depicted in the images above via scanning electron microscope is a cutting tool with the Stealth coating (left) and one without (right).

Four-flute Stealth end mill series are available, with a cutting diameter of 1/32 to ¼ and overall length of 1.5-4".
