Surface set diamond bit is mainly recommended for drilling soft to hard formations. Generally speaking, surface set diamond bit can provide satisfying penetration rate.
To choose a right surface set for the formations drilled, we need at least consider the following aspects: diamond size, diamond grade, profile design.
