In the case of machining aluminum with a forming tap, aluminum deposits grow larger after every hole. Eventually, the pitch diameter becomes so enlarged that the part becomes oversized and needs to be scrapped. A coating with increased anti-seizure properties may even be able to aid where poor coolant quality or concentration is a problem.
