So I ordered a TW-1 online and no bits fit on it. Not even the 3/8 adapter that came with it. You can see the picture I attached, that is pressing a bit with moderate force where it started to dig into the drive. It's like the drive is too oversized.
I was gonna send it back. But just thought about filing it down a bit. I am pretty sure someone here has encountered this with a tool. Should I just hit it with a file? Or just wait to get a new one?
