1. A grinding tool comprising:
a substrate; and
at least one abrasive particle affixed to the substrate, wherein the abrasive particle has a base, and four tips adjacent to one another protruding from the base, the base having a cavity of a generally cross shape extending between the four tips, the cavity including a material discharge surface disposed between two adjacent ones of the four tips, the material discharge surface being located at an end of the cavity and adjacent to a side surface of the base, an inner material angle between the material discharge surface and the side surface being between about 120 degrees and about 160 degrees, and a region of the cavity between two adjacent ones of the four tips having a ridge, the abrasive particle having a greatest height variation taken from the ridge that is between about 40 μm and about 120 μm.
