More effective than traditional metal bonded.cup wheel. Both wet and dry use. Can be used for both cutting and grinding. Mainly used for grinding of granite, marble, concrete, ceramic.
Metal Round Grain Pads /discs are used for heavy to medium grinding of granite, concrete and other types of stones. 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.
Vacuum brazed diamond grinding pads/discs are very aggressive, and long lasting too. Compare to brazed diamond cup wheels, they are as aggressive with less noise; compare to resin bond or metal bond diamond pads, they are mover aggressive and efficient; compare to electroplated diamond discs, they are as or more aggressive, but more durable. They are extremely good at shaping and removing lippages on granite, marble and concrete. They can also be used on glass and swimming pool surfaces.
Diamond grinding wheels are meant for high resistance to wear. Metal Bonds tend to give particularly long life, but are generally inferior to resin bonds with regard to material removal rate.
Usage:The use of coolant for metal bonds is a must. In exceptional cases of small contact surfaces, dry grinding may be employed.
Vacuum Brazed Diamond Grinding Wheels are the most effective and fastest cup wheels on the market today. They serve a dual purpose - they cut as well as grind. The diamond Grinding wheels have diamonds on both the surface and the rim, allowing the user to cut and shape with the same tool.
