Surface Set Drill Bits

We bring forth for our clients superior quality of Surface Set Bits. It differs from the impregnated diamond type in that they are set with a single layer of natural drill diamond on the working surfaces of the bit crown in a predetermined pattern. The diamonds are mounted in a bit crown powdered metal matrix body that is fused to a steel tool body or shank. Unlike impregnated diamond bits where the controlled erosion of the powdered metal bit crown is desirable to expose new diamond crystals, the metal bond matrix used for all bits is extremely tough and wear resistant. The function of the bit crown matrix body on a surface set bit is to securely hold the diamonds in position throughout the operational life of the bit. Our range primarily recommended for use in drilling relatively soft, abrasive, unconsolidated formations that are not effectively drilled by impregnated diamond bits. This is also recommended for use in drilling harder formations where the available rotational speeds and bit loads are insufficient to use impregnated diamond bits due to drilling equipment limitations.

Fordia s line of surface set core bits meets the needs of drilling companies operating in differing ground conditions. With a choice of diamond grades ranging from coarse to fine, and a variety of profiles, choosing the appropriate surface set core bit is now easier than ever.
