    How to set up air blast for dry milling on maching center?

    I am looking at milling 4140PH (Rc of 30) and from some reading the recommendation is to dry mill with air blast for chip removal as coolant will cause thermal shock to the carbide and early failure. Doing this in a maker space (not my machine) so limited on what I can set up or modify on the machine. I know it has coolant setup but not aware of any provision for air blast. How is this usually done other than just hand holding an air hose to keep the chips away from the cutter?

    There is always going to be someone that says no coolant is better in some cases it can be better, roughing 4140 is good to do without coolant, but finishing will give you better tool life and better finish with coolant, and this won't cause thermal shock when finishing, it has a lot to do with speeds / Feeds the Tool being used and the rigidity of the part and the machine plus spindle Hp correct chip load is important, and use max depth of cut
