  • Cutting oil/coolant choice

    A friend of mine is drilling and chamfering holes in saw blades. These are custom blades for specific machines. He is setting up a large CNC milling machine for the task. He is wondering what is the best coolant for the task. What do you use and why?

    Thanks in advance

    Hi,

    What ever is in the coolant tank right now. Most coolants these days are good for a wide range of materials. Personally, I prefer a synthetic myself.
    If you think you understand what is going on, you haven't been paying attention.

      If the machine is dedicated to drilling saw blades only use a cutting fluid rather then coolant. If the machine is general purpose and will be used on other materials such as aluminum and plastics then plain water coolant is the best bet.

      Screw machines running steel parts often use cutting oils rather then plain coolant, it also lubricates the machine.

      It is very messy.
