guys,
what type of grind wheel makeup should i order to sharpen my tungsten on a standard bench grinder that takes a 6" wheel with a 1" shaft hole ?
curious what you guys are using.
at work we use a belt sander, but everyone uses it for all kinds of different things and im afraid its contaminating our tungsten when we use it.
we have a grinder that nobody uses and want a dedicated wheel for it. the current wheel we have, not sure what its made of, its green in color, wears out really quick, not hard enough.

thanks guys..
