The present invention addresses problems in the diamond saw blade and segment art. One aspect of the invention comprises a method for making handleable, strong, discrete, metal-clad abrasive pellets. This method comprises the steps of:

Diamond pellets and saw blade segments made therewith

The invention is directed to cubic boron nitride (CBN) particles coated with a thin inner layer formed by the reaction of a reactive glass or ceramic to form a chemical bond and, optionally, an outer layer of a vitreous material. The particles are useful as abrasive particles in a vitreous bonding matrix. In addition, a method of preparing the particles and abrasive tools containing the particles are encompassed.

Coating for improved retention of cbn in vitreous bond matrices

The present invention provides saw blade segments comprising polycrystalline diamond cutting elements and single crystal diamond cutting elements dispersed in a bonding matrix. In a preferred embodiment abrasion resistant particles are included so as to cause non-uniform wearing of the cutting segments. In another aspect of the invention, cutting segments are provided which utilize surface set polycrystalline diamond cutting elements larger than mesh size 18.
