sml-pdcbit on 21 Nov 24Introduction to the Structure of PDC Drill Bit PDC drill bit relies on the cutting teeth installed on the drill bit body to cut through the formation. These cutting teeth have two structures: the compound sheet cutting teeth and the columnar teeth. Their structures and installation methods on the drill bit vary. Compound sheet cutting teeth are formed by directly welding the composite sheet into the grooves reserved on the drill bit body. It is generally used for body drill bits. Columnar cutting teeth are formed by welding the composite sheet onto the tungsten carbide column and then embedding or welding the teeth into the holes on the drill bit body. It is generally used for steel body drill bits and also for somebody's drill bits. Click for PDC drill bit factory.
