Can you have them water jet to remove the flamecut?
 

Highfeed cutter would be my next thought. 

They cut the blanks already so there is not enough material. Next order we will.

 

They had the faces Blanchard ground

If you've the horsepower and through coolant these guys could care less about flame cut

We typically take a 2.5" LOC and .25/.38 radial cut with these tools in flame cut HY100

I really have to stay on the operators to use through coolant though.

They want to turn it off because it's messy.

These tools are very strong but require strong through coolant to flush the chips

They will pack up with chips and destroy themselves in short order without through coolant

The cutter bodies are $1K+ and it costs $700 to for a set of inserts so a lazy operator

can cost you a whole lot of $$$ in a hurry
