After trying every tool possible to remove that stripped wheel nut, you may be ready to take a saw and just remove the entire wheel stem. Save your stem as well as your sanity and remove that pesky nut with a little help from a Dremel tool. Handheld and easy to operate, Dremel tools have a wide variety of bits for performing various functions, including a bit reinforced with aluminum oxide to cut through metal.
Affix the cut-off wheel to the cut-off wheel mandrel. The cut-off wheel is a small, round disc with a hole in the middle. The mandrel has a small screw on the tip for securing cut-off wheels, and a stem for insertion into the Dremel tool. Insert the mandrel screw through the hole in the disc and use a screwdriver to secure the wheel at the tip of the mandrel.
Insert the mandrel with the cut-off wheel into the head of the Dremel tool. Tighten the head of the tool to ensure that the bit is properly seated. Some tools are tightened by hand, while others have a small wrench for tightening.
Put on safety glasses to protect your eyes while you're cutting through the wheel nut.
Turn on the Dremel tool to high speed.
Hold the Dremel tool with the wheel perpendicular to the top of the wheel nut. Use the edge of the spinning wheel to slice a notch in the top of the nut. Hold the tool steady and use moderate pressure, allowing the tool to cut through the metal naturally. Make a notch deep enough to insert the tip of a chisel.
Position the chisel in the notch at a slight angle.
Tap the back of the chisel with a hammer to loosen and unscrew the nut. If you find that the nut is stripped and turns without coming off the stem, the nut will have to be cut completely off.
Use the Dremel tool to slice through one side of the nut, stopping when you get to the stem. Slice through the nut again on the opposite side, again stopping at the stem.
Hammer the chisel into one of the cuts and use it to pry off the two halves of the nut.
