It is widely acknowledged within the manufacturing industry that PCD tools deliver excellent results when reaming nonferrous metals and abrasive plastics. Reaming with a PCD tool allows the user to ream holes faster, to tighter tolerances and produce cleaner-edge holes than is possible with carbide or HSS tooling. 

In addition, by producing cleaner edges, a PCD reamer can reduce, or even eliminate, the need for secondary finishing operations such as deburring, thereby lowering overall production costs. PCD reamers provide consistent results for a longer time than their traditional counterparts, because production does not have to be periodically interrupted to change worn tools. (Note: As with HSS and carbide, PCD edges can be sharpened to extend their working life.For a manufacturer engaged in steady production, a carbide tool might last a few days to a week, while a PCD tool could last for months. Experience shows that during production reaming, the extended tool life a PCD reamer provides, along with reduced secondary operations, typically results in a cost per hole that equals 20 percent of the cost per hole when a carbide reamer is used.
