I've not used induction coil heater on this drain plug, yet!This is a really good idea.. would love to see if the real-world impact is as good as the theory.
Also yes to all the above, especially reducing adapters/extensions to keep the plane you pull on the breaker bar as close to the face of the plug as possible. This reduces the bending force on the bit and tendency to walk out.
But did just have opportunity to try on a 100 series busted stabilizer bracket bolt. I first tried without use of heat, no movement. Then after just 5 seconds of heat, bolt turned easily.
