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

That is definitely a great option. I don't have
one so my go-to was carbide and coolant.youbare in great shape
with the oven
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.
