So I was turning a pair of salt/pepper grinders using marble wood and Yucatan rosewood. It called for a 1 inch Forstner hole. Very soon after starting the rosewood, the thing started smoking due to bit friction, etc. I was using water with Dawn to cool it off every half centimeter or so, but it didn't help much. Worse with the marble wood. I tried to file the cutting edges, but the stank just kept coming and my house smells of burnt wood now. So, is there a way to sharpen Forstner bits other than "new Forstner bit"?
