For those of you that flute barrels, what kind of Lube or Coolant do you use? I run my 3 inch 3/16 HSS cutter around 300 rpm at about 1.5 inches per minute. I start by plunging to full depth - about .095, turn on the power feed and walk away. This is what works for me and I am not interested in changing it. I have been using Rustlick PB-10 and there is only about a cup full left in the 5 gallon bucket that a friend gave me about 15 years ago. I dilute it about 5 to 1 with distilled water. That PB-10 is so old that I can't even find any info on it. It must have been banned by the EPA. It works well but it is about gone. What do you use?
thanks
