The Definition of Diamond Dressing Tools

Diamond dressers consist of single-point or multipoint tools brazed to a steel shank, and used for the truing and dressing of grinding wheels. The tools come in several types, including: grit impregnated, blade type, crown type, and disc type. 

The advantages of multipoint over single-point tools are: the whole diamond can be used; in a single-point tool, when the point is blunt the diamond must be reset, and after few re-settings the diamond is replaced.

Multipoint tools have higher accuracy, especially in form grinding, where blade types are used. Blades consist of elongated diamonds. The thickness is controlled and blades are available in thicknesses from 0.75 to 1.40 millimeters (0.030 to 0.055 in).

Grit-type tools are of a tough grade, and can be used for bench grinders. Since small points are used, the diamonds have a cutting edge with natural points, unlike single-point tools, which have bruted points.

The cost of multipoint tools is lower, since smaller, less expensive diamonds are used.
