| The drill bit and stabilizer gauge is a flexible, elongate strip that is wrapped about the circumference of a drill bit or drill bit stabilizer to measure the diameter. The strip has a rectangular tab at one end with a slot defined therein so that the opposite end of the strip can be inserted through the slot after being wrapped around the drill bit or stabilizer. A zero pointer is stamped on the tab adjacent the slot to ensure accurate measurement. A scale is imprinted on the strip with markings at each interval of π times the dimensional unit and fractions thereof for reading the diameter directly. The gauge is made from spring steel, a thermoplastic material, or other suitable, inextensible, flexible material which has sufficient elasticity, but also sufficient stiffness, that the strip may be bent into a loop retaining a nearly perfect circular form. | ||||||

| An impregnated diamond core bit is sharpened at the bottom of a bore hole, the bit being secured to the outer barrel of coring apparatus attached to a tubular drill string extending to the top of the bore hole. A sharpener is releasably mounted in the lower end of an inner core barrel lowered through the drill string into the outer barrel and latched thereto, with the sharpener projecting below the lower end of the core bit, the sharpener having nozzles for discharging abrasive material pumped through the sharpener against the drilling face of the bit to sharpen the same, whereupon the coring operation can be effected in the usual manner, the core releasing the sharpener from the inner barrel and pushing it upwardly along and within the inner barrel as the core is formed. The sharpener is retrieved with the inner barrel upon release of the latter from the outer barrel and its upward removal through the drill string to the top of the bore hole.
