Deep Hole Drilling Exotic Alloys: Parameters for Hastelloy, Stellite, Monel, and Waspaloy
Hastelloy, Stellite, Monel, and Waspaloy are not as common as Inconel 718, but when a job comes in requiring one of them, the parameters that work for standard steel will not work at all. These materials combine work-hardening, abrasiveness, and low thermal conductivity in ways that punish mistakes. Here is what I have learned about drilling each one. Common Characteristics of Exotic Alloys All four of these materials share properties that make deep hole drilling difficult: ...
