Wireline Drilling Surface Set Diamond Hq3 Core Bit

In most cases, surface set diamond bits will provide higher rates of penetration than in softer formations due largely to the greater degree of exposure of the individual diamond crystals.

To choose a right surface set for the formations drilled, we need at least consider the following aspects: diamond size, diamond grade, profile design.
