PSA, powertools, physical injury
So here's a PSA: if you intend to buy an angle grinder, DO NOT buy one that's continuous-operation. A safe cutting tool MUST have a switch that automatically turns the tool off as soon as you stop holding it, a so-called "dead man's switch".
Consider what happens if you accidentally drop your angle grinder, and it doesn't have automatic turn-off; the disc can hit the floor, which will launch it off in a random direction, which is potentially going to be your legs.
It can and will severely injure you if that happens, possibly fucking up your legs irrecoverably, for the rest of your life.
Do not buy continuous-operation cutting devices.
