Diamond Dressing Tools - Toolroom Dressing

Norton Toolroom Dressing Tools are primarily used on surface grinders to form the grinding wheel to an exact concave or convex radius. Although some tools are designed for use on a specific machine, many radius tools can be used on any grinder having the correct set-up.


Primarily used on 8" diameter and smaller vitrified toolroom wheels, Norton offers a selection of three types of radius tools and phono-point tools.

  • Concave Radius Tools – A specially-shaped single point diamond, designed for forming concave radii on small diameter grinding wheels. Not resettable.
  • Convex Radius Tools – A specially-shaped single point diamond, designed for forming convex radii on small diameter grinding wheels. Not resettable.
  • Half-Circle Concave Radius Tools – A specially-shaped diamond set in the side of the shank for forming half-circle radii on small diameter grinding wheels. The tool is rotated to form the radius. Commonly called a “rat tail dresser.” Not resettable.
  • Phono-Point Tools – For general toolroom concave and convex dressing on small diameter grinding wheels. Not resettable.
  • Thread Grinding Tools – These tools are used on J & L and Excello thread grinding machines to accurately dress the grinding wheels that form the desired thread configuration (non-resettable).
  • Internal Grinding Tools – Q style shank is used on a Heald internal grinder (resettable).
    R style shank is used on a Bryant #5 internal grinder (resettable).
