| A method I use that works universally is a variable speed reversible powered drill and a steel drill bit. You can get screw extractor bits too, but in a pinch, even wood drill bits work. |
| Just power the stripped screw with a bit in reverse; it eventually cuts enough grooves to pull it out, if it slips too much just work it out enough to use long nose pliers. |
| For some really bad screws, it can help to first drill forward into the screw to cut a few grooves, thereafter reverse the drill. |
| Cutting a long groove with Dremel's thinnest emery cutting disc creates a simple slotted screw head, but you can supplement it with the drill method to get enough clearance to keep from cutting the surface of your devices chassis. |
| The above method may work on a Dremel tool, but drills always work, they have low speed, but a lot of torque. |
