If you run a rotary machine with counter rotating heads, be sure to get 1/2 clockwise and 1/2 counter clockwise PCDs when you order.
The weight of the machine is partially supported by the large surface area of the diamond segment – this segment limits the PCD’s penetration into the concrete.
The diamond segment lightly dresses and helps remove the severe marks left by the PCD grinding teeth.
This configuration will yield a higher total square foot life span while providing an aggressive rate of coating and concrete removal.
Use these PCD scraper to remove heavy coatings, overcoats, glues, mastics, thin set and paint.
