The dresser is manufactured from a hardened and tempered polished steel handle and fitted with a diamond tip. Regular truing and dressing of vitrified grinding wheels removes worn abrasives and waste materials that have become embedded into the grinding wheel. This restores the cutting face for optimum performance and helps to minimise vibration. Single point diamond dressing tools are suitable for use on most surface, cylindrical and internal grinding applications. Tip: 0.50 Carat Diamond. Suitable for bench grinding wheels of 150mm to 250 mm diameter.
