Hand drill earthen: a description of the design, the choice. Manual drills for earthwork

In the farm of any summer resident or gardener there will definitely be a couple of tools for working the land. The main one will be a shovel, which can not only carry out the cultivation of the soil, but also dig holes. However, such a tool will not cope with the tasks of forming small borehole holes with a diameter of up to 200-250 mm. For this it is necessary to use either a manual earthen drill or professional mechanized equipment. It is obvious that in most cases the first option will be more rational, even if it is necessary to create several mini-wells.

Construction drill

Hand drill design

The device tool is so simple that many make it at home with their own hands. Another thing is that the factory design wins in strength and reliability.

Immediately it must be emphasized that almost all elements of the drill are made of metal - high-strength steel with anti-corrosion coating.The basis of the design is a tubular rod with a sharp tip. In order to improve the usability of the manual drill for excavation, a T-shaped handle in the form of a welded crossbar made of a metal pipe is provided on its upper part. By the way, rubberized wear-resistant linings can be provided on the handles. In the lower part above the tip, the working equipment is fixed in the form of a two-blade cutter of different diameter.

Main characteristics

Hand drill cutters

Among the key parameters for selection, two characteristics can be noted: the diameter of the working cutter and the depth of drilling. As for the first value, three dimensional formats are common: 150, 200 and 250 mm. The best for domestic use in the same garden area is a 100 mm hand-held earth auger, with which holes are made for seedlings, wells for columns of hail, as well as pits for laying supports for utilities. But if it is planned with the help of a drill to develop small wells or install pile foundations, then at least you should look closely at a diameter of 200 mm or even 250 mm.

With regard to the depth of drilling, the minimum immersion is 75-100 cm. Such holes are made by almost all models of the tool in the base configuration. Monolithic structures are capable of fulfilling 150-centimeter wells, but for a depth of more than 250 cm, a special extension cord is already required, which is mounted on the main rod by means of screw fastening. When choosing, consider the possibility of disassembly, which is provided for in a manual earthen storm of universal purpose.

You should not ignore such an indicator as the thickness of the main rod. It depends on the reliability of the design. It is desirable that its diameter is not less than 20 mm, but there is no special point in excessive thickening, because it makes the drill heavier, and this is an additional load on the muscles in the process.

Varieties of earth hand drill

Above was considered the simplest design with the most common characteristics, but manufacturers increase the possibility of using hand-drills, which necessitates the need to improve their device. In addition to the standard design, there are the following modifications:

  • The drill with removable mills of different diameter. The advantages of such models include the ability to create wells for any purpose, and the disadvantages are a decrease in strength due to non-monolithic working parts.
  • Earth screw auger. The manual principle of excavation involves the presence of two-blade cutters, however, it is more convenient to form deep holes with screw cutting blades such as auger. Therefore, the device handles suggests the possibility of rotation by two users.
  • Foundation drill. A special type of tool specifically designed to create holes for piles. The device is distinguished by the fact that in the lower part, when the drill is buried, it is possible to create extensions under the ground, without at the same time thickening the wellbore itself.
Ground drill

Manufacturers

Domestic products from the companies Agroimpex-Oka, Kalibr, SIBRTEH, Gigant and others are widely represented in the segment. The average cost of the models of these manufacturers is 700-1000 rubles. For example, Gigant offers a hand earthen drill of 200 mm in working diameter with a depth of 100 cm for only 750 rubles.

Among foreign products there are functional and technological models FIT and Fiskars, but they are more expensive. Fiskars QuikDrill with the same characteristics is estimated at 4 thousand.rubles, as in its working part knives are used with a special profile, which makes it easy to cut the soil, making a minimum of effort.

What else to consider in choosing?

First of all, attention is paid to the technical and operational parameters of the drill and the characteristics of the wells being developed. With regard to the nuances of the choice of working equipment, then for shallow typical holes it is advisable to choose lightweight monolithic drills with average depth and diameter parameters. As a universal tool, the best hand drill for excavation is one that has a combined structure both in terms of the installation of cutters and in the device of the bearing rod, which allows for the possibility of extension.

Do not overdo the presence of special protective coatings that will protect the metal base from scratches and corrosion. The preference is given to the models processed by gloss powder paint.

Manual ground auger with ground receiver

Manual Boot Tips

The main rule to be followed when using the tool is to use it strictly according to its intended purpose. It is necessary to avoid stony soils, as well as the creation of wells with parameters that do not correspond to the technical characteristics of a particular model.There is no need to ignore support from auxiliary devices - soil receivers, tripods and levers for pulling out the device in case of its jamming expand the functionality of the equipment. Proper maintenance will help to maintain the optimum performance of the earth hand-held drill. After each working session, the structure must be cleaned, washed and lubricated with technical metal oil.

Conclusion

Earth hand drill

Manual garden equipment is under serious pressure from the drive mechanisms. This is observed in different areas, the Boers are no exception. Ergonomic and productive models of tools with hydraulic, electric and battery power fillings are developed especially for the household segment.

Obviously, in terms of performance and ease of use, they have advantages over standard hand drills, but for earthworks in a small area of ​​dignity, their use may be superfluous. If a season requires the creation of several wells for planting trees, for example, then it is quite possible to do with a manual model, especially since power structures cost more and require preparation of a power source or fuel.
