Found the stl on the internet. Got it off some russian cnc forum. Imported the stl into Estlcam and it sets up your roughing and finishing actions for you. Have to edit the gcode though. It adds in a pause to change out the bit, I’ve no clue how to get repetier to restart, so I just removed the bit changing parts, did everything with the rotozip bit. As for tempering, it wouldn’t help, they’re just high speed steel, so they’re as hard as they’re going to get.
