Choosing augers for motor-drills

Motorized drills are used in various industries. The tool is useful for drilling ice, soil, for agricultural and forestry work. The main piece of equipment is the auger. This article will tell you about its features and types, the best models, as well as the main selection criteria.

The main component of a motor-drill looks like a metal rod with one or more screw edges and is a replaceable part. Drilling takes place thanks to the torque generated by the auger. The result and duration of work depends on the quality of the product. High quality steel is used in the production of screws. The auger is a metal piece of steel pipe with a welded-on metal screw band.

The mechanism is intended for manual operation. The auger is not capable of punching concrete, stone or deep holes. Auger drilling involves a passage up to 20 m. However, the tool is very popular in the agricultural and forestry industry when it is necessary to make holes for seedlings. Also, augers are indispensable for fishermen when ice fishing or installing small fences.

The main features of the element:

• strength and reliability of the structure;
• work with hard soil, loose soil, clay;
• the possibility of using an additional extension to increase the depth of the holes;
• the steel used in production has wear-resistant properties.

The types of screws are distinguished according to the following criteria.

• By the type of connecting mechanism. The element can be made in the form of a threaded connector, a trihedral, a hexagon, a cylinder.
• Borax type. Depending on the type of earth tool, augers are for abrasive soil, clay or loose soil.
• By the pitch of the screw tape. Augers for augers are available with a long helix pitch and are used for working with soft soil. Elements with a small pitch are used if it is necessary to break through shell rock, stone blotches or hard soil rocks.
• By the type of spiral, the element can be single-threaded, progressive single-threaded and double-threaded. The first type is characterized by the location of the cutting parts on one side of the drill axis. The cutting elements of the second type of auger are located along a complex trajectory with overlapping areas of action of each cutter. The third type includes augers with cutting parts on both sides of the auger axis.
• By size. Auger sizes vary depending on the purpose of the tool. For simple earthworks, elements with a diameter of 20 or 25 cm are suitable. They are able to make a hole up to 30 cm deep. There are options in lengths of 50, 60 and 80 cm. It should be noted that extension rods can be used, which increase the hole depth up to 2 meters. The additional element is available in lengths of 300, 500 and 1000 mm. Soil augers are available in sizes 100, 110, 150, 200, 250, 300 mm. For ice surfaces, it is better to use a mechanism with a length of 150-200 mm.

In order to choose a component for a gas drill, take into account such values.

1. The power of the mechanism itself.
2. Torque parameters.
3. Features of the size of the landing site.
4. Type of connector with a motor-drill. It can be threaded, triangular, hexagonal or cylindrical.

Along with these parameters, it is necessary to take into account the characteristics of the soil and the features of the tasks. There are two-start options with multiple cutting parts, which are equipped with a single pick-up guide. The cutters are made of high quality steel and have a wear-resistant tip.

There are no replaceable knives in inexpensive models. The cutting head is welded to the main structure, which significantly reduces productivity and productivity. However, such products are suitable for small household tasks. A few more nuances of choosing a screw.

• Length. Products are produced in lengths from 80 to 100 cm. The choice of an element depends on the type of tasks.
• Diameter. The parameter varies from 10 to 40 cm.
• Connector values.
• The gap between the turns of the screw tape. Long distance is best for soft ground, short distance for high density soil.
• The density of the involute.

To increase the drilling depth, use special auger extensions. They come in lengths from 30 to 100 cm. The use of an additional extension makes it possible to increase the depth of the holes up to several meters. When purchasing products for ice drilling, the main attention is paid to the diameter of the product. Elements designed for soil will not work. When working on an ice surface, the diameter of the created hole differs from the size of the cutting element. An instrument with a diameter of 20 cm creates a depression 22-24 cm wide.

When choosing a drill auger, the purpose of using the recess is taken into account. For example, if it is planned to install piles or pillars, then the concrete products should not come into contact with the walls of the hole. Cement mortar is poured into the gaps. Therefore, piles 60x60 mm are installed in holes made by a screw with a diameter of 15 cm.For the section of a column 80x80, an auger with a diameter of 20 cm is taken.

When creating holes for fences, many users recommend choosing universal motor drills. Screws with a diameter of 20 cm are suitable for them. In addition, you can purchase attachments 15 or 20 cm long. The first type is designed for holes for small piles, the second for larger ones. A screw diameter of 30 cm is used less often. Most often it is taken to create holes for heavy large fences.
