1 Claim. (01. 255 -42) This invention relates to a core bit andmore particularly to a diamond set core bit for drilling oil wells. I

As is customary in drilling operations, a drilling annular body I I, formed of metal or of a metallic inner'and outer surfaces I2 and I3 are substanfluid, or drilling mud as it is called, is pumped 5 tially cylindrical and are relieved at their ends, down through the hollow drilling head assembly as at I5 and IE, to form annular shoulders that to flow outwardly over the workin face of the lie inlongitudinally spaced planes. Said shouldrill bit and upwardly in the hole or well. In ders l5 and 16 have functional purposes in conthe case of diamond set bits, surges in the fluid nection with the other elements of the drilling pressure at the bottom of the hole will often cause head assembly with which the core bit [0 is to be bumping of the working end of the bit against associated in the setting up of the drilling equipthe bottom of the hole with consequent damage ment. The convex end surface I4 smoothly joins to the diamonds by being broken against hard the inner and outer cylindrical surfaces I 2 and formations. Such surging may be due to pump l3 but with a curve of lesser radius to form the surges or to faulty pump circulation, but bump- 5 inner contour [1 than the radius of the curve ing may also be caused by the provision of Water ming the outer contour l8. courses in the working face of the bit of insufiih Surfaces 4 and I3 constitute the workvcient volume to accommodate the Volume of ing face of the core bit and, for this purpose, are culating fluid that must escape from the inside set with abrasive particles, or diamonds, indicated of the t to t t i if balanced flow is to be 20 at i9. The diamonds H! are individually set in maintained. If an out-of-balance condition obthe mold usedin making the core bit l0, and are tains, sufficient pressure may build up to lift the arranged n predetermined P s and With bit up off the bottom of the hole, with the result v rying lengths of the diamonds pro rudin from that when this excess pressure is relieved sudh fac f the y, r in W ch the demy, the eight of t drilling equipment may diamonds are set. For instance, the diamonds force the bit down against the bottom of the hole l9 over the end surface [4 protrude rather subwith a striking blow that may break the diamonds stantiaily f m the Surface in Which y are set, in the working face of the bit. but the diamonds, indicated at I9a. along .the Ihave now found that by a proper construcouter cylindrical surface I3 gradually become tion and design of a diamond set core bit and flush :with the surface down toward the lower with a novel arrangement of water courses, the d, or shoulder I 6 of said surface, tendency of excess-fluid pressure to build up and he Working face of the core bit is provided relieve itself in the manner described is largely With a plurality of symmetrically arranged radiminimized or even eliminated entirely. This reating grooves 20, which serve as water courses for sult is accomplished in accordance withthe prine ow of drilling fluid from the interior of the ciples of my invention I by providing auxiliary drilling assembly radially aCI'OSS e Working face water grooves in a novel and effective arrangef he core bit and upwardly along the outer ment with respect to the working face of thecore surface Is.
