Gotcha. Drilled that bolt out nice and easy. But dumb fuck REALLLLLLY slammed that bitch in there. Easy out actually just machined more out instead of pulling the damn bolt out. So I'll have to drill the hole out and replace with helicoil. I didn't realize how many tools I didn't have until I started having to dig this broken bolt out. Makes me wonder the last time I broke a bolt... it's been years! Point and case, I don't have any of the bolt extraction tools. Hell, I had to go buy a set of EZ-out's.Saying the cutting surfaces of the two drill types are different. You want to cut a ribbon off the bottom of the hole so no hammer. On the hammer setting it is going to bounce around before it gets a chance to get a good cutting going. The Hammer rated drills are usually beefed up a bit through the body and bearings and more powerful so a good choice, you just don;t need the hammer function for aluminum. You have a great tool there.
Thanks for the tip Paul, wish I would have posted here before I went to the store. Oh well!
