Deep Hole Drilling Plastics and Composites: PEEK, Delrin, Nylon, and Filled Materials
I have spent years dialing in gun drilling parameters for steel, aluminum, and titanium. When the first batch of PEEK medical components landed on my desk, I assumed the same principles would apply with lighter cuts. I was wrong. Plastics and composites behave fundamentally differently under the cutting edge, and deep hole drilling amplifies every one of those differences. Here is what I have learned the hard way so you do not have to. ...
