The rule here is 10 gpm per inch of drill diameter. A .500inch diameter drill needs 5 gpm to achieve the high pressure effect; a .250inch drill needs gpm. The most frequent problem is coolant holes that are just too small. The drill must be capable of passing enough coolant, or it just won't perform properly.
