Drill bit (well) Wikipedia

Drill bits are broadly classified into two main types according to their primary cutting mechanism. Rolling cutter bits drill largely by fracturing or crushing the formation with "tooth"-shaped cutting elements on two or more cone-shaped elements that roll across the face of the borehole as the bit is rotated.

Petropedia What is Drill Bit? Definition from Petropedia

A Drill Bit is a cutting tool used to cut or crush rocks. Everything present on drilling rigs assists the bit directly or indirectly in cutting or crushing the rocks. Drill bits are attached to a drill in order to create holes and power them for cutting through the workpiece, typically by rotation.

Roller Cutter Bits Air and Gas Drilling Netwas Group Oil

Roller cutter bits use a crushing action to remove rock from the cutting face and advance the drill bit. The weight or axial force that is applied to the drill bit is transferred to the tooth or teeth on the bit. These teeth are pointed (mill tooth bit) or rounded (insert tooth bit) and the force applied is sufficient to fail the rock in shear and tension and cause particles of the rock to

Three Cone Bits. A drilling tool designed to crush and remove rock efficiently while incurring a minimal amount of wear on the cutting surfaces. As the drillstring is rotated, the bit cones roll along the bottom of the hole in a circle. As they roll, formation is removed by either a digging or crushing action.

A tool designed to crush rock efficiently while incurring a minimal amount of wear on the cutting surfaces. Invented by Howard Hughes, the roller-cone bit has conical cutters or cones that have spiked teeth around them. As the drillstring is rotated, the bit cones roll along the bottom of the hole in a circle. As they roll, new teeth come in contact with the bottom of the hole, crushing the
