Before grinding the bit, the main cutting edge of the bit and the grinding wheel surface shall be placed on a horizontal plane, that is, when the edge contact the grinding wheel surface, the whole edge shall be ground. This is the first step in the position of the bit relative to the grinding wheel. Set the position and then slowly lean on the grinding wheel surface.<\/p>\n\n\n\n
