Drill bit, английский
- One of a number of different types of detachable cutting tools used to cut circular holes in rock, wood, metal, etc. also called drill crown in africa and england.
- The cutting tool at the bottom of the drill pipe which bores into the formation. there are many different types and styles of cutting faces and materials used for drill bits, and these are tailored for specific types of rock, or formations. drill bits range in size from 3-3/4” (95.25 mm) to 36” (914.4 mm), and drill bit sizes are limited by the kind of casing pipe used to keep the well from collapsing. roller cone-type and pdc (polycrystalline diamond compact)-type bits are most commonly used.
- The cutting or boring element used to access oil or gas in the drilling process. not only are most bits roller-cone bits, but the drill bit also typically includes both the cutting element and the circulating element.

- Churn drilling. portable drilling equipment, usually mounted on four wheels and driven by steam-, diesel-, electric-, or gasoline-powered engines or motors. the drilling is performed by a heavy string of tools tipped with a blunt-edge chisel bit suspended from a flexible manila or steel cable, to which a reciprocating motion is imparted by its suspension from an oscillating beam or sheave, causing the bit to be raised and dropped, thus striking successive blows by means of which the rock is chipped and pulverized and the borehole deepened; also, the act or process of drilling a hole with a churn drill. extensively used by the diamond-drilling industry to drive pipe vertically through difficult and deep overburden or fractured barren ground before coring operations with a diamond drill. also called american-system drill, blast-hole drill, cable drill, cable-system drill, cable-tool drill, rope-system drill, shothole drill, spudder, spud drill, well drill.
Core drill, английский
- A drill used to remove a sample of rock in situ, for determining bedrock profiles or for obtaining a core for testing; the sample is retained in the core barrel.
- A mechanism designed to rotate and cause an annular-shaped rock-cutting bit to penetrate rock formations, produce cylindrical cores of the formations penetrated, and lift such cores to the surface, where they may be collected and examined. see also adamantine drill, calyx drill, diamond drill, rotary drill, shot drill.
- The act or process of producing a cylindrical core of rock, using a core-drilling machine and equipment.
