Cheap eBay 3" cordless angle grinder
Added 2024-11-21 13:20:15 +0000 UTCA very cheap cordless angle grinder from eBay that was cheap for a reason. The tool itself is OK, but the batteries are not able to supply the initial inrush current to the motor, and cut out on overload.
When used with a compatible battery from a cordless ratchet, the angle grinder performs surprisingly well. I was able to slice the damaged end off my retired stainless steel spudger and put a new tip on it.
One other issue I have with this, is that the only thing that stops the motor rotating inside the housing seems to be small plastic pips that slot into where the motor end cap is crimped on.

They're held together with three clips, so it's not that hard to open them. It could be viable to add the other MOSFET if the batteries themselves were capable of supplying the current.
