Single Row for the FASTEST Grinding

The Single Row PCD cup features a single row of diamond segments, providing the least amount of surface drag. In turn, this design results in the FASTEST surface grinding action and removal of materials.

A high diamond concentration segment on a balanced steel body provides a long service life. Expect a continual high performance from this tool due to the consistent diamond distribution.

Available in most sizes with threaded or non-threaded arbors.

Quality Level: Professional Grade, 30/40 Grit


Med/Hard Materials: Cured Concrete/Granite/Masonry/Natural Stone

Equipment: Angle Grinder

How to Use:

  • Choose the correct specification and diameter for your application.
  • If the cup is non-threaded, it comes with a 7/8” arbor hole and a press fitted 7/8”-5/8” brass bushing. This allows the grinder’s lock nut retainers to hold the cup in place.
  • Always review the manual for safe mounting procedures. Assure that the grinder flange is clean and free of burrs so that the cup seats the flush.
  • Maintain the RPMs of the grinder and do not force the cup. For a smooth finish, keep it moving in a steady motion over the floor to avoid gouging.
  • Make sure the grinder is functional. A bent spindle or dirty flanges will cause the cup to wobble.
  • Check the bearings on the grinder and see if the segments wore unevenly. Even if a grinder bearing is out of round, a diamond cup will wear to that angle and will grind successfully.
