Feature:<> Bare diamond particles, sharp grinding, high efficiency. Brazed polishing discs have a longer service life and are more durable than traditional polishing discs. The new brazing process can firmly fix the diamond particles on the substrate, not easy to fall off, the diamond density is high, and the sharpness is more wear-resistant. The sharpness is high, the incision is smooth, the cemented carbide steel is the matrix, the sand is evenly distributed before and after, and the sand surface is widened at the same time. The thickened base body is more stable, hard to break, and has a good balance. Uses: Polishing and cutting marble, granite, artificial stone, glass, ceramics, agate, jade, and thin metal iron.
