How dose a dry diamond core bit work?
A diamond core bit does not cut but works by milling. During the
sharpening process performed at the factory, individual diamond
crystals are exposed on the face and sides of the segment and it is
these that do the milling work. The metal matrix holds each diamond
in place. During the work, each diamond is supported by a comet’s
tail which strengthens the supporting action of the bond
immediately “behind” the diamond crystals.
A diamond tool properly suited to the material to be cut, the
equilibrium between the work of the diamond and the
abrasion-resistance of the bond is optimum; the diamond is held in
place until it is destroyed and new crystals appear. It is in this
equilibrium that all the quality of the diamond tool resides.
