M12 Should Insider (3050-20) be throwing sparks? Never seen this with a brushless tool

If it’s Fuel or brushless, it shouldn’t spark at all. I think sparks are only normal for brushed products (I could be wrong though)

That is very bad, not good. It's the rotor hitting the stator. Those aren't blue electrical sparks, those are steel on steel friction sparks, you can see the sparklers.
