Description:

Surface set diamond core bits can be used with any type of core barrels, To avoid excessive matrix wear at the leading edge of each segment.Tingsten carbide inserts are fitted on each side of the waterway.This kind of bits cannot be used in broken or loose formation.

Surface set bits provide higher rates of penetration than impregnated bits in soft formations due to the greater degree of exposure of the individual diamond stones.

A range of surface set core bits are manufactured to the highest quality standards to give long service life and maximum penetration in soft to hard formations. The range includes a variety of diamond grades, stone sizes and face profiles enabling a cost effective solution to be taken for most conditions.
