Very friable, micron-grade cutting edges which bring premium surface finishing, rough crystal surface which bring best retention with the bond, micron-fracture mode,excellent self-sharpen ability brings high free cutting rate and cool cutting.

Irregular shape, friability, lots of sharp cutting edges, few inner impurity, lowest magnetic, perfect self-sharpen which balance the grinding performance and tool oI life. it is ideal for very hard tungsten carbide grinding.

Irregular shape, friability, self-sharpen ability, higher cost performance, which is ideal for cost consideration.

Polycrystalline diamond, micro fracture mode, irregular shape with multi micron grade sharp cutting edges, good self-sharpening ability. Its characteristics make this type of
diamond can continuously generate sharp grinding edges which bring good efficiency and better for dry grinding.

Angular shape, sharp cutting edges, owns electric conduction, high thermal resistance and toughness, it is ideal for high speed grinding and heavy cutting force application.
