Precisely controlled man-made GE diamond crystals 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. Extremely long tool life results from new diamonds becoming exposed as the point or disc is used on metal, porcelain, glass, or stone.

Maintains Cutting Rate Far Longer

While tungsten carbide cutters and plated diamond points or discs are initially sharper, they loose their sharpness and wear out much faster than sintered diamond tools which can be "re-sharpened" as often as desired by slowly turning it (@4,000 rpm/15 sec.) against a wet dressing stone (10333, pg. 5) to expose new diamond particles. This should also be done to a new sintered point for best results.

The myriad of partially embedded diamond crystals leave a velvety surface finish which is desirable in many applications and is closer to a final polish than with carbide or plated diamond tools.

Despite a unit cost higher than plated diamonds or abrasive stones, sintered diamonds actually represent the most economical choice for many applications. They will last 5 to 10 times longer than plated diamonds which only have a single layer (sometimes two) of diamonds on a metal surface, and up to 100 times longer than various types of silicon carbide or aluminum oxide mounted abrasive points with far less grinding dust.
 

Hard Binder/Fine Grit (A) is for hard precious stones and metal finishing work (especially gold) when contamination of the surface prior to application of porcelain is a potential problem. Not recommended for use on ceramics and glass.
