[GTALUG] (very off topic) quality die grinder bits

[William Park]

Hi all,  Very off topic, but I'm fed up.

I sharpen my lawn mower blade with die grinder.  Problem is, all the 
bits that I bought from Canadian Tire, Rona, and Home Depot, they all 
wobble. Except for one bit. And, that has been used so much that I need 
a new one, now.

If anyone has die grinder, what brand of grinding bits do you recommend?
