Use a carbide endmill and coolant. No need to anneal
Anyone happen to know the alloy most likely to be used for carbide insert tool holders? My guess is 4140. I have four that I need to mill down to work in an AXA holder. They test at 45 HRC. Thinking about annealing them before milling and then heat treating
again, so I would like specs to use.
