Get AUGER DRIVE

An auger drill bit is more useful than a Forstner bit for removing waste material from a borehole (during drilling). Although Forstner bits can drill faster and is capable of producing a flat bottom hole, whereas auger bits have a larger guide screw, they cannot produce a flat bottom hole.

Simply put, an auger is a spiral-shaped tool that is used to drill holes into the ground and other surfaces or materials. The spiraling metal shaft with a blade at the end of the device is known as a “flighting”. The flighting rotates to scrape, cut, or siphon out drilled materials.

An auger drive is a drilling device or bit that includes a rotating helical screw blade to remove or drill out material. The rotation of the blade causes the material to move out of the hole being drilled.

Projects with a need for multiple shallow holes in softer soils should choose auger drilling, whereas projects with a need for deeper holes in a larger variety of soil types should choose mud rotary. This is a generalisation, and other factors may influence which method to choose in a real geotechnical investigation.

There are four types: the clay, sand, coarse sand and a combination auger, each is manufactured with a standard bayonet connection or a conical screw thread connection. A hand auger set will form the basis of most environmental researcher's 'tool kit'.

Auger drilling uses a drill bit that looks a lot like a screw—it's made of steel casing, with curved flights that are rotated while the rig drill head applies pressure to move the bit further into the ground. The rotation of the flights is important, because it mechanically moves material to the surface.

Auger drilling is the simplest form of drilling. It involves the manual rotation of a helical screw into the ground, usually by two people although auger drills can also be mounted to small vehicles. Once the auger drill is deep enough, the earth is lifted up by the blade of the screw.
