TL/DR: Best angle grinder? -Preferably one that I can swop battery packs with same brand decent cordless hammer drill since my trusty TE-6 is still not functional.
I have a need for an angle grinder. No - not to break into caves (I find soaking the padlock in a mix of HCl/HNO3 is more subtle and leaves no traces), but to cut up some diving tanks to make novelty toilet roll holders. Might as well buy a battery one as it might come in handy if I
run out of acid need to use it to remove my ladders from Wigmore Swallet and the krabs have rusted shut. A drill that uses the same batteries and isn't shonky would be useful. For drilling shot holes not bolting. I let Max do the latter - he's taller than me and can tie knots properly.
