    en.wikipedia.org/wiki/Drill

    A magnetic drill is a portable machine for drilling holes in large and heavy workpieces which are difficult to move or bring to a stationary conventional drilling machine. It has a magnetic base and drills holes with the help of cutting tools like annular cutters (broach cutters) or with twist drill bits .

  3. Drilling - Wikipedia

    en.wikipedia.org/wiki/Drilling

    Titanium drilling. Drilling is a cutting process where a drill bit is spun to cut a hole of circular cross-section in solid materials. The drill bit is usually a rotary cutting tool, often multi-point. The bit is pressed against the work-piece and rotated at rates from hundreds to thousands of revolutions per minute.

  4. Scientific drilling - Wikipedia

    en.wikipedia.org/wiki/Scientific_drilling

    Scientific drilling into the Earth is a way for scientists to probe the Earth's sediments, crust, and upper mantle.In addition to rock samples, drilling technology can unearth samples of connate fluids and of the subsurface biosphere, mostly microbial life, preserved in drilled samples.

  5. Drill press - Wikipedia

    en.wikipedia.org/wiki/Drill_press

    A drill press is a drilling machine suitable for quick and easy drilling of straight holes, countersinking or counterboring that are perpendicular to both directions of a table surface. In comparison, it is more difficult and less repeatable to drill perpendicularly with a hand-held drill.

  6. Boring (earth) - Wikipedia

    en.wikipedia.org/wiki/Boring_(earth)

    Boring is drilling a hole, tunnel, or well in the Earth. It is used for various applications in geology, agriculture, hydrology, civil engineering, and mineral exploration. Today, most Earth drilling serves one of the following purposes: return samples of the soil and/or rock through which the drill passes; access rocks from which material can ...

  7. Annular cutter - Wikipedia

    en.wikipedia.org/wiki/Annular_cutter

    The tube clamping device is a metallic device that is clamped on the tube with an adjustable chain. After clamping the device the magnetic drilling machine is placed on the device, which gets clamped to the device by switching on its magnet. With the help of magnetic drilling machines' proper RPM, the annular cutter makes a perfect hole in the ...

  8. Well drilling - Wikipedia

    en.wikipedia.org/wiki/Well_drilling

    Well drilling is the process of drilling a hole in the ground for the extraction of a natural resource such as ground water, brine, natural gas, or petroleum, for the injection of a fluid from surface to a subsurface reservoir or for subsurface formations evaluation or monitoring.

  9. Magnetic drilling machine - Wikipedia

    en.wikipedia.org/wiki/Magnetic_drilling_machine

    A portable magnetic drilling machine is faster and more portable alternative to hole making machines such as the drill press, and is more accurate than a hand drill. A portable magnetic drilling machine is used on steel or other magnetic materials. It gives an accuracy of 0.01 mm to 0.05mm in steel or other magnetic material.
