diamond breakage
PGD used a smaller diameter drill to "bulk sample" the pipes. This is a great idea for saving some drilling dollars, but it seems the downside is an increase in diamond breakage compared to a larger diameter bauer drill.

Xdebeers, can you please elaborate on why a larger drill is more expensive to use, or is it as simple as the bit costs more? Thx in advance.
