The problem is I do not know the alloy. I guess I will use the 4140 specs.

I have a heat treating oven right next to my mill, so I would rather use the oven.

Are short of squirter bottles or endmills?
Not an option for me.

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.
