impregnated bit
A sintered, powder-metal matrix bit with fragmented bort or whole diamonds of selected screen sizes uniformly distributed throughout the entire crown section. As the matrix 1587 wears down, new, sharp diamond points are exposed; hence, the bit is used until the crown is consumed entirely. Compare: multilayer bit
