These grinding wheels have surface grinding segments that are best for grinding hard materials and removing heavy stock on flat surfaces. They provide a cool, free cut, long life and fast stock removal for maximum productivity.

Type-to-Application Recommendations:

• Type 27:
  • Use 0.045”, 1/16” and 3/32” Thick (Type 27/42) for cutting only, where fast cutting and low kerf loss are desired. Ideal for pipe cutting.
  • Use 0.125” Thick for cutting and cleaning root pass welds.
  • Use 1/8” Thick for cutting-off, notching and light side grinding.
  • Use 1/4” Thick for grinding with low horsepower air and electric grinders or where low pressure is used.
  • Use Z24 Long Life, 1/4” Thick for grinding with high horsepower machines (3hp or higher) and heavy pressure; flame cut and other severe applications.
  • Type 28:
    • Use Saucers for smooth, gouge-free griding at shallow angles.
    • Type 29:
      • Use Gold Flexible for polishing and blending applications.
