HANS is a leading provider of metal bonded superabrasives that are specially designed to withstand wear and tear. Our Metal Bonded Diamond Tools are made by embedding diamonds into specific metal alloys in a way that allows them to cut through a variety of materials, including tile, glass, and sapphire.
During the creation process, we carefully mix the diamonds with the Metal alloys to ensure that the tool is optimized for cutting efficiency. As the tool is used, the material that the diamonds are embedded into must wear away in the correct proportion to the diamonds themselves, allowing them to continue cutting optimally.

Metal Boned and Sintered Diamond Wheels was a Professional Grade Wheels for Vertical Cabbing Machines,It has a Full mm deep diamond matrix exposes new cutting points as the Wheels are used.Sintered Wheels can be dressed to expose additional crystals for a more aggressive cut, but dressing is not always needed if you follow a "side to side" pattern when grinding to ensure even wear. Dynamic balancing at the factory ensures concentricity for smooth and quiet grinding .Generally order one grit size larger for sintered diamond tools as compared to plated or brazed parts.
