A drill bit is a hole-forming metal tool that fits in a drill's chuck. All drill bits, regardless of type, have a pointed cutting type. Bits are available in a wide range of sizes rated in numbers (wire-gauge bits), in fractions (fractional bits), in metrics (metric bits) or by a letter designation (letter size bits).
An accessory placed in the chuck of the drill that enables the drill to create holes in such surfaces as metal, steel, wood, and plastic.
Any one of a number of different circumference steel tools used to put a circular hole in a bowling ball.
the cutting tool used in a drill. It is held in the chuck and cuts into the material as it rotates
a bit used in drilling for oil
A tool with very tough steel or diamond teeth that grind rock into small chips during drilling. The diameter of the bits used to drill a well may range from more than 22 inches at the upper part of the hole, to less than four inches at total depth.
Because of its hardness, diamond is often used in high quality or high performance drill bits.
The part of the drilling tool that actually cuts through the rock. Drill bits bore a hole into soil, sand or rock by a combination of crushing and shearing actions. Drill bits used for extra-hard rock are studded with thousands of tiny industrial diamonds, the hardest substances known.
a drilling tool coated with diamonds which cuts through rock.
the component at the end of the drill string that cuts the rock and makes hole. (See Tricone bit and PDC bit)
The cutting devise used to drill a well. It is typically made of hardened steel, and may have industrial grade diamond components.
n: the cutting or boring element used in drilling oil and gas wells. Most bits used in rotary drilling are roller-cone bits. The bit consists of the cutting elements and the circulating element. The circulating element permits the passage of drilling fluid and utilizes the hydraulic force of the fluid stream to improve drilling rates.
Tool or apparatus, either manual or power operated, also called a drill, which is used for boring holes in wood, metal, stone, etc.
Drill bits are cutting tools used to create cylindrical holes. Bits are held in a tool called a drill, which rotates them and provides axial force to create the hole. Specialized bits are also available for non-cylindrical-shaped holes.
