Angle Grinder
I once had an HP laptop with a dodgy power connector. I managed to procure a
replacement from Alibaba for about 0.001c, but the original proved rather tricky to remove. My poxy 25 watt soldering iron couldn't generate enough heat before the metal can surrounding the connector radiated it away.
Judicious application of a 10,000 RPM 7" diamond cutting blade made short work of the metal can and I was able to remove remnants by "metal fatigue". The remaining pins were no bother for the mighty 25W iron.
Youngest daughter was much impressed and Dad's hero status reinforced.
