I picked up a cheap die grinder to finish off some mod's to my lathe. The grinder works well enough for me but the stones suck.
First off, I know absolutely nothing about what each of the colors represent and it doesn't seem to matter, as all three colors of these cheap stones wear out equally fast, and I do mean FAST! I now have a bunch of 1/8 and 1/4 dowel pins....
So, would anyone be kind enough to give me the Die Grinder Stone 101 on-line tutorial?
100: What does each color represent relative to grit and hardness?
101: What is each color more suited to application and material wise?
102: Where does one get a nice set of stones... that last long enough to actually remove some metal?
Thanks....
