a note on the orange grinders at HF, they do a good job and ive gotten both of mine stuff a couple times, no problems (even major brand ones can burn up if they get stuck, but no such issues here) but the one problem to beware of is that the 4 screws on the body right under the grinder wheel can get loose after use, and you dont want 14 000 rpm falling apart on you, so either periodically check or get some screw locking stuff like loctite
