Drilling with augers is the most efficient way of making wells for various purposes. The auger is precisely the exchangeable drilling tool. He stares at the hydro rotator, which is a helical structure. Its length is strictly defined, and on the surface along the entire length there are turns of a certain diameter. It is now possible to buy augers for drilling without unnecessary problems.
The lower part of the auger initiates the drilling process, therefore it is endowed with a bore element and guide teeth. They help overcome the resistance of the rock and ensure its further cutting and lifting to the surface. This part, as a rule, is not replaceable, but it is characterized by the greatest wear and tear. It is she who determines the life of the auger and this piece of equipment is worth paying attention to if you decide to buy augers for drilling .
The screw sizes are different and are determined by three parameters:
- in length they can be from half a meter to 6 meters;
- trunk diameter is from 10 centimeters to 1.5 meters;
- the pitch of the threads is 15 to 30 centimeters, and the smaller it is, the better the soil will be extracted.
They are subdivided according to the type of soil in which a hole is to be drilled. Abrasive type augers are best suited for drilling in sands, clay and earth where stony inclusions do not exceed 10%. Rock devices are used to drill rock with rocky inclusions up to 30%.
In addition to the main augers, various extensions are also offered, the length and diameter of which is determined by the customer. There are also screw extensions that extend exactly the screw part of the auger.
