product usage

Segmented Design: The wheel has segments with strategically placed gaps that allow for efficient debris removal and cooling during operation.

Aggressive Grinding: Turbo Cup Wheels are known for their aggressive grinding action, making them suitable for tasks that require substantial material removal.

Arbor Compatibility: They are available with different arbor sizes, such as 5/8"-11 or M14, ensuring compatibility with different grinders.

Versatility: They are versatile and can be used on various surfaces, including concrete, stone, and masonry.

Fast and Smooth Grinding: The turbo design helps in achieving both fast and smooth grinding results.

Q: Should I use a Single Row or Double Row cup wheel?

A: A Double Row cup wheel provides a smoother finish and lasts longer, making it great for general concrete leveling. A single-row wheel is more aggressive and removes material faster but leaves a rougher surface.

Q: Can I use this grinding wheel on granite?

A: Yes, our Turbo segment cup wheels are specifically designed for natural stone like granite and marble. They minimize chipping and provide a smooth edge ready for polishing.

Q: Do I need to use water with diamond cup wheels?

A: Johnson Tools cup wheels can be used Dry or Wet. However, using water helps reduce dust and keeps the tool cool, significantly extending the lifespan of the diamond segments.
