An auger is a drilling device, or drill bit, that usually includes a rotating helical screw blade called a "flighting" to act as a screw conveyor to remove the drilled out material. The rotation of the blade causes the material to move out of the hole being drilled.
The parts of circular cross-section which are symmetrical about the axis of rotation are made by
Electron beam welding (EBW) is a fusion welding process in which a beam of high-velocity electrons is applied to two materials to be joined.
EBW is often performed under vacuum conditions to prevent dissipation of the electron beam.
Structural sections such as rails, angles, I-beams are made by
Structural shapes that can be made with this metal forming process include I-beams, H-beams, T-beams, U-beams, angle iron, channels, bar stock, and railroad rails.
The most commonly rolled material is structural steel.
It is made by Hot rolling.
A hacksaw is a fine-toothed saw, originally and mainly made for cutting metal. On hacksaws, as with most frame saws, the blade can be mounted with the teeth facing toward or away from the handle, resulting in cutting action on either the push or pull stroke.
V-Blocks are precision metalworking jigs typically used to hold round metal rods or pipes for performing drilling or milling operations.
They consist of a rectangular steel or cast iron block with a 90 degree channel rotated 45 degrees from the sides, forming a V-shaped channel in the top.
