We choose, design and upgrade manual drill

Hand drill - irreplaceable thing in the garden. To drill boreholes for the installation pole for a fence or bored piles under the foundation, make the hole for planting the plants. This hand tool is always a use. What drill to choose how to do it yourself if you can somehow improve borax factory-made? These questions know the answers to users of our portal.

Before you buy or make your own hand-drill, we must ask ourselves the question:

• For what purpose and work you need one?
• What type of soil to be drilled on the site?

Sand, rocky ground, tugoplastichnye clay loam soil with a large number of roots. Drilling of the pit for the installation of fence posts small diameter drilling of "heavy" soil under powerful bored piles for the foundation of a house. All these factors have a significant impact on the design of a manual drill.

Mikhail Sukhanov (User FORUMHOUSE):

In my opinion, the best drill - a drill, which is "locked up" under a job at a specific site, taking into account the characteristics of the soil and its layers. Those. the drill should be done under certain tasks.

Users of our portal offers the following construction of the drill improvised. As it is made, it can be clearly seen in this photo.

Two knives are used for preliminary loosening of the soil, making it easier to insert the tool into the ground the main blades, divorced at an angle. Moreover, the main blades can be interchangeable, attach them to the nuts and bolts. Because of this, it is possible, using one rod, drill shafts of different diameters.

Although externally purchased and homemade drill are very similar, it is often self-made drills show the best results. They are durable, easier to work with them, because They are made "under him."

Mikhail Sukhanov (User FORUMHOUSE):

Me and my neighbor once conducted an experiment: we decided to compare the efficiency of my home-made brown (diameter blades 25 cm), and its purchase borer (diameter 14 cm blade).

The soil at the site forumchanin this:

• 0.7-0.8 m - "plodorodka";
• 0.2-0.4 m - limestone coarse fraction;
•  Further marl layer (yellow, a limestone fine crumb).

During the competition drillers almost simultaneously Deepen 0.8 m. Then purchase a drill hesitated on marl, while working homemade brown, Michael I continue to drill, as if nothing had happened. Neighbor also had to loosen marl with a crowbar and then to drill further.

The result of the experiment: the fact that the drill hole depth of 1 meter, at Mikhail It took a little more than 5 minutes, with he is not tired. The neighbor is the last 0.2 m hopelessly behind.

The so-called Universal drill, as it is suitable for working on different grounds, is often ineffective.

Therefore, among the users of our portal so popular self-made designs of hand drills. To do this drill, enough junk materials and basic skills in welding.

Done so the drill: take a round or square tube, its length is selected depending on the intended depth of the pit. In the case of deep hole drilling pipe can be extended by building up its additional barbell. The diameter of the drill blade is selected depending on the intended diameter of the pit, and planned activities.

As the blades are proven sawing large diameter wheels on conveyers. Such a disk grinder is sawn into two parts. The halves are welded to the pipe, the blades should be diluted to a certain angle (about 25-30 °). So they better deepened into the ground. By the end of the tube is welded peak or "killed" large diameter drill. The tip is needed for centering the drill bit at the beginning of the drilling. Due to the saw teeth on the blades of a drill during the rotation well nips the roots.

The main thing when working with hand drill - time to stop and pick it up from the pit to dump rock.

I produced the beginning of the summer season two of the drill. The first - with a diameter of 210 mm, the second - 160 mm. On the blade wheels went by conveyers. The rest is made of what is literally strewn under the feet. Also made collapsible extender-rod. All about everything I spent 200 rubles, as they say, cheap and cheerful.

If the hand is not the welding machine, such a drill can be collected only at the nuts and bolts. Also, as the bur on netyazholyh soils and for drilling small diameter holes can be used auger b / y ice screw (because buying new - idea economically unjustified). For the convenience of working in ice auger should be cut-handle brace and attach a standard T-shaped gate.

Besides the above-described drills, interesting approach to the manufacture of self-made drill for drilling wells with a nick forumchanin VyacheslavK.

Drilling to a depth of 2.5 m ordinary garden bur was made. Forumchanin grinder blades cut the sheet metal piece 3 mm thick, which was pre-glued paper template.

Then, the obtained preform was drilled hole 20 mm in diameter.

According radius of the circle was made incision.

Further VyacheslavK welded into the blade pin, in which it started the pipe. The pipe is also welded to the blade.

Pin imprisoned.

The result here is a drill.

In the course of a drill to identify and eliminate such shortcomings:

• Blades for drilling are reduced, which significantly reduces the efficiency of drilling. To the blade is not reduced, between them and the pipe were welded septum-stretching.

• When drilling the drill, if he stumbles on stones or roots, leads to the side. To overcome this drawback, one blade, from the circle fold space was welded to the arc-shaped rim 30h10 cm.

• Low efficiency of the drill during the passage of fat clay. It was made for the so-called works of clay drill frame design of our website user with the nickname KND.

This drill works best when it is the work of the lamellar clays. It has a minimal coefficient of friction of the rock. It is easy to extract from the pit (no "piston effect", like the auger). After lifting the drill clay simply shaken out of frame.

Although this drill is most often used in drilling wells homemade "water", the design turned out to be so successful that it is necessary to focus attention on it.

VyacheslavK so did the drill:

From 5 cm wide metal strip he cut two identical strips and the bevels made angular, departing from the end of the strip 2 cm. For the bands, you can use old car springs.

Cut and sharpened knives.

Welded blades to drill, sending sharpened sides in opposite directions.

Threw knives apart using the corner so that the distance between the ends was 25 cm.

With pipe wrench VyacheslavK He turned the knife at an angle.

I assemble and weld the whole structure.

It should be noted that the drill bit broke off quickly. therefore VyacheslavK imprisoned chip, as shown in the photo.

In the manufacture of the frame of the drill should be noted that it is not suitable for use in a loose, granular soils, since he does not remain in the frame.

Also interesting design drills intended for manufacturing broadening - "heel" - when building foundation TISE.

Subarist (User FORUMHOUSE):

I finalized the purchase drill. I put him second hinged blade. To drill it was convenient to work, made the T-handle 1 m in length. Thus, I have increased the force on the lever. Rod Length - 3 meters. Now drill pits depth of 2 meters can be, standing at full height, not fours. The teeth cut from zemlepriomnika because from them a little persuasion.

In this "uluchshayzing" drill is not ended. To increase the efficiency of the drill when drilling broadening Subarist arched blades - straight cut bad ground. In further forumchanin plans to put the blade of stainless steel, because usually quickly tupyatsya stones.

Council: making foundation type TISE, basic pit is best to drill a conventional drill or augers, and the "heel" to drill special drill to "pan-zemlepriomnikom" and two folding blades. This will save time and effort.

ValentM (User FORUMHOUSE):

I did the drill, using as a primer drive ordinary saucepan. So I did a drill broadening at a depth of 2.5 m.

Bottom pans made the stoppers that rest against the ground. When drilling expansion pan stands stillIt increases efficiency, as not wasting time on cranking of zemlepriomnika. When you rotate the knob, walking on the threaded shaft, discloses blades which cut the soil. Once the pan is filled, the handle is twisted in the opposite direction, the blades are formed, and the drill is lifted to the surface. 4-5 ups pit with the broadening of fully drilled.

It is worth considering what to do this drill harder than normal - required welding machine and lathe.

However, the design has turned out successful and popular. Using this principle, the forum users do their drills with two blades that are more likely to work in tandem with augers.
