My new drill press has all kinds of cool features I never had before. One of them is a bottle with a control-flow spout to run lubricating fluid while drilling.
Many years ago I used water mixed with light mineral oil, dripping it onto stuff manually. More recently I have been just applying Rapid Tap from time to time (generally I have not been drilling big holes).
What does everyone use these days? Specifically, given the ability of continuous flow of lubricant and its collection under the table (and recycling??).
