Summary. The rate of penetration (ROP) obtained with a roller-cone bit is limited by either the cuttings-generation or cuttings-removal process. An ROP model that includes the effect of both the initial chip formation and cuttings-removal processes is presented. Laboratory observations show that the reduction in ROP at high borehole pressure is the result of …

Milled Tooth Bits operate on the principle of mechanical cutting. As the bit rotates, the teeth engage with the rock formations, creating shearing forces that break the formation apart. The drilling fluid, often referred to as drilling mud, is used to carry the cuttings to the surface, cool the bit, and provide lubrication for efficient drilling.

The Roller cone bit performance ROP will also be affected by the rotary speed of the bit and an optimum speed must be determined. The RPM influences the ROP because the teeth must have time to penetrate and sweep the cuttings into the hole. The figure below shows how ROP varies with RPM for different formations.
