Douglas Caraway,John Hayward,Malcolm R. Taylor,Tom Scott Roberts,Steven Taylor,Graham Watson +5 more
TL;DR: A rotary drill bit for use in drilling holes in subsurface formations comprises a bit body having a leading face and a gauge region, a number of blades formed on the leading face of the bit and extending outwardly away from the axis of a bit so as to define between the blades the number of fluid channels leading towards the gauge region as discussed by the authors.
Patent
Pdc cutter with stress diffusing structures
TL;DR: In this article, a PCD cutting element for use in earth boring drill bits where die interstices remote from the working surface are filled with a catalyzing material, and the adjacent to the working surfaces are substantially free of the catalyzing materials is described.
Patent
Rotary drill bits having nozzles to enhance recirculation
TL;DR: A rotary drill bit for drilling holes in subsurface formations comprises a bit body having a leading face and a gauge region, and a plurality of cutting elements mounted along the leading edge of each blade, and there is provided, in one or more of the channels, a main nozzle which directs fluid along one blade so as to clean and cool the cutting elements on it as mentioned in this paper.
