Diamond blades: dry cutting and wet cutting

A diamond cutting blade is fabricated with diamonds fixed in a metal matrix. This tool has many purposes such us to cut, slice, slab, wafer, cut-off, groove, slot, singulation, cross sectioning, and more. Diamond cutting blades can be bonded through a rim or segment, a metal core or with sintered metal powder. The diamonds remain in place thanks to the metal matrix, so the blade can live longer.
