They have a lot of features that other diamond polishing pads or diamond cup wheels do not have.

They are more aggressive and longer lasting than regular resin bond, or resin-metal bond diamond polishing pads since they are pure metal bonded (no resin) diamond pads.

Compare to diamond cup wheels, they are as aggressive and as longer lasting but are flexible. This feature allows these metal bond diamond grinding discs to get into curved areas for grinding purposes
