Thor made excellent qualtiy tools.
I had a Shopmate drill in similar straits. In my case, the brushes wore
out. If this is the problem with yours, you can take the drill to a
motor shop and they can either find a set of brushes that will fit, or
sell you some you can file to the correct shape. If a bearing has
failed, those were almost all standard bearings, and a bearing shop can
help probably sell you one. You might have to ream it to the correct ID
It's a big job, and to be honest, I'm not convinced it's worth it. I
replaced mine with a Bosch rotohammer/drill and have been much happier
with it than my old drill. There are good quality tools out there, but
you'll never find them at Home Despot [sic].
Sure, "Scrum" is a weird name, but "Assault and Battery" was already taken.
