    2004-7-22 · The drill bit used diamond‐impregnated cutting segments, which were selected for dry drilling in soft rock. Scanning Electron Microscopy (SEM) coupled with Energy Dispersive X‐ray Spectrometry (EDS) was used to determine the matrix constituents. Figure 1 shows the Backscattered Electron (BSE) image of the surface of the cutting segment.
