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.
Noteworthy Features:
Engineered for precision in core drilling within thinner stone applications like granite, marble, sandstone, and limestone. Elevate your drilling experience with finesse in delicate stone materials.
Our customers have consistently praised the excellence of our products. We are confident that you too will experience the same level of satisfaction. Should you require any customization, please do not hesitate to contact us. As the leading manufacturer of diamond tools, we are committed to providing you with the best solution possible.
