Buying Guide for Primer for Large Pores:

  • The motor of a right-angle grinder determines its capacity. It is measured in amps, and the higher the amp rating, the greater the capacity. Choose an angle grinder with a minimum of 7 amps for heavy-duty duties.
  • Angle grinders are available in various diameters ranging from 4.5 inches to 9 inches in diameter. For light-duty or domestic use, a smaller grinder will suffice. However, a larger grinder will provide more power and efficiency for heavy-duty duties.
  • RPM is the unit of measure for angle grinder speed. (rotations per minute). The grinder will rotate quicker the higher the RPM.
