electroplated diamond cutting discs are more suitable to be used on dry cutting. For they have very high concentrated diamonds rigidly bonded on the surface by nickel alloy and the diamond particles protrude from the bond. The nickel bond electroplated diamond cutting discs are particularly suitable for beginning cutting operation. They can be used for cutting many hard and abrasive materials such as marble, granite, thermosetting plastics, GRP, pre-sintered and pre-fired (green) materials, electro carbons, graphite, soft ferrites, farinaceous products, pc boards, and etc.
