Sintered Diamonds last 5 to 10 times longer than plated diamonds and up to 100 times longer than various types of silicon carbide or aluminum oxide mounted abrasive points. They work with far less grinding dust and can be re-sharpened to expose new diamond particles as often as desired by slowly turning (@4,000 rpm/15 sec.) against a wet dressing stone. Plated diamonds typically have only a single layer of diamond on a metal surface. Even new sintered points should be dressed for best results. Dumont¨ sintered points come in a Hard Binder of 100 Micron/120 Grit for hard precious stones and metal finishing work (especially gold) when contamination of the surface prior to application of porcelain is a potential problem.
Dumont sintered diamonds have controlled man-made GE diamond crystals that are molded into a metallic binder with extreme heat and pressure in a special atmosphere. This produces a uniform matrix of more consistent diamond crystals than natural industrial diamonds embedded in a strong, durable binder. Made in Belgium. 25,000 RPM Max Speed.
