Milling tools made of PCD (polycrystalline diamond) are 
high-performance cutting tools that are used for milling extremely 
hard and 
abrasive materials. PCD is a synthetically produced material consisting of microscopically small diamond particles that are sintered under high pressure and high temperature in a metal matrix (usually cobalt). These diamond particles are polycrystalline, i.e. they consist of many small 
diamond crystals which together form an extremely hard and wear-resistant material.
 The main advantages of PCD milling tools are their exceptional hardness and abrasion resistance, which makes them ideal for 
milling non-ferrous metals such as aluminum, copper as well as 
plastics, fiber-reinforced plastics (CFRP/GRP) and other abrasive materials. They offer 
outstanding cutter life and enable very high 
machining speeds during milling, which can lead to a significant 
increase in productivity. 
PCD tools are characterized by their ability to produce extremely smooth surfaces during milling. This makes them particularly 
valuable for applications where a 
high surface finish is required without the need for reworking. Although 
PCD tools are 
more expensive to purchase than conventional milling tools, the costs are amortized by their 
long service life and the reduction in machine downtime due to tool changes.
 Due to their specific properties, 
PCD milling cutters are primarily used where high demands are placed on 
machining quality and 
efficiency.
