SINGLE POINT (SP) diamond dressers use a single diamond and must be used at the correct angle feed or they are easily chipped or blunted. It is impossible to consume the entire single diamond but it can be resharpened several times.
DIAMOND GRIT (DG) wheel dressers use small pieces of diamond in a sintered matrix and are replacing single point dressers for many applications. They are easier to use and cost less per carat diamond compared to SP dressers.
DG dressers must be used at 90 deg direct from the grinder toolrest so they never chip or become blunt as there is a continuous supply of sharp diamond point available. No resharpening cost is necessary and 100% of the diamond can be used.
