From All Dip grinders, have been oriented to work simply and efficiently without compromising the grinding quality. You cannot achieve this goal though, without controlling the quality of the grinding discs.
Carefully designed and cured, all our burrs can be re-sharpened 2 or 3 times if installed and used properly.
A fair cost is also important. It makes no sense to have a good grinder if you cannot afford to keep its burrs in proper condition.
