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.

Diamond Grades

Drill 1 : Very good quality, processed, well rounded diamonds, free from flaws for medium to very hard fromations.

Drill 2 : Good quality, processed, rounded diamonds, free from flaws for soft to medium formations.

Carbonado : Microcrystalline natural diamonds with a very tough structure, used in severe drilling conditions where conventional natural stones tend to fracture, such as badly fractured formations.
