Drill cuttings [1] are broken bits of solid material removed from a borehole drilled by rotary, percussion, or auger methods and brought to the surface in the drilling mud. Boreholes drilled in this way include oil or gas wells, water wells, and holes drilled for geotechnical investigations or mineral exploration. [2]
A post-hole auger. An earth auger, earth drill, or post-hole auger is a drilling tool used for making holes in the ground. [1] It typically consists of a rotating vertical metal rod or pipe with one or more blades attached at the lower end, that cut or scrape the soil.
A continuous flight auger drill is used to excavate a hole and concrete is injected through a hollow shaft under pressure as the auger is extracted. Reinforcement is then inserted after the auger is removed. [1] This creates a continuous pile without ever leaving an open hole.

A gimlet is a hand tool for drilling small holes, mainly in wood, without splitting. It was defined in Joseph Gwilt's Architecture (1859) as "a piece of steel of a semi-cylindrical form, hollow on one side, having a cross handle at one end and a worm or screw at the other".
A brace is a hand tool used with a bit (drill bit or auger) to drill holes, usually in wood. Pressure is applied to the top while the handle is rotated. If the bit's lead and cutting spurs are both in good working order, the user should not have to apply any pressure other than for balance: the lead will pull the bit through the wood.
Pilot holes may be used when driving a screw, typically in wood, concrete, or plastic where the screw cuts its own threads. When a screw is driven into a material without a pilot hole, it can act as a wedge, generating outward pressure which can cause many materials to split. By drilling a small pilot hole into the material, into which a screw ...
A part's-eye view of a boring bar. Hole types: Blind hole (left), through hole (middle), interrupted hole (right). In machining, boring is the process of enlarging a hole that has already been drilled (or cast) by means of a single-point cutting tool (or of a boring head containing several such tools), such as in boring a gun barrel or an engine cylinder.
