QuickChange Trapezoid Pads with PCD segments and sacrifical bar
- PCDs with a metal button or sacriﬁcial bars are less aggressive and are designed for thin coating removal.
- PCDs without a metal button or sacriﬁcial bars are very aggressive and designed for thick coating removal. They will leave a very coarse proﬁle on the concrete.
- Important: PCD tools are direction speciﬁc. Always check the direction of rotation of the grinding heads.
