FORADEX – DIAMOND TOOLS PRODUCER

 FORADEX S.A.’ DIAMOND TOOLS PLANT was founded in 1970. This plant manufactures diamond drilling tools “surface set” type with natural diamonds and PDC bits. All types of drilling tools, used in oil and gas drilling are produced, as well as drilling bits, cutiing rings, rectifiers, reaming shells, etc. for the slim hole drilling.

I . OIL DRILLING BITS

 Current types and dimensions produced by FORADEX are shown in the following tables, but the actual range can be extended if any other type is requested.
