Typically, I tell people who *need* to drill aluminum dry to run at about
70% of the RPm shown on my chartsWe are relatively conservative with our numbers because when it comes to drilling, most people don't need CNC-type speed. ...So don't slam me for being so slow and out of touch! :)
I'm wondering if there is a rule of thumb any of you follow for such procedures?
