Overview of the screwdriver drill with his own hands
I have long wanted to write this review, but always postponed because I wanted the most remarkable and interesting ideas to leave for later.
- You already wondering what we observe today?
Today we have done a drill their own handsWhich is attached to the screwdriver from the Croatian blogger workaholic Doctor D.S. As always, we look at from all angles invention and draw objective conclusions. (How it works I will show at the end.)
- Why workaholic? - You ask.
On his channel for more than 100 video clips with various inventions, which he does their own handsSubstantially from scrap materials using a minimum amount of instruments.
- Let's not drag and start.
Idea
Grade 5 of 5
The basic idea of this invention to horrible simple. Using disk raspilochnogo wood author makes drilling tools small pits. The resulting holes may well be suitable for fence posts. himself Boer author is in the form tips on the screwdriver.
In assessing the reasonableness of the creation of such a drill
their own hands - I want to note that the idea seems to be quite rational, and a drill can be useful almost to any garden.(Sam this year put a fence, had to take this tool borrowed from a neighbor).
Very surprised by the author's decision to make a drill of raspilochnogo disk, and taking into account all of the above, for the item safely put 5 points.
Design
Evaluation 3 of 5
Constructive solution of the drill, is also quite simple. Sawn disc to its center, then the angle welds on metal rod. The rod as a nozzle set on screwdriver and begin to drill.
Constructive solution and its ease I like. It should be noted that the author did not, any superfluous elements, as is usual in many homemade products.
This solution meets the stated characteristics, namely, by using this drill, it is possible without any problems, in fact, to drill a small hole.
In a video made by hand-drill, the author attaches the screwdriver and drills using it.
This decision, I would question, not sure screwdriver can withstand this load. At the site of the author, I would have made an ordinary pen that would drill to use in manual mode.
Due to the fact that the drill design is not bad, but use as a nozzle, in my opinion, it is not reasonable, have to put 3 of 5 points.

Evaluation 3 of 5
Design It tool no, I do not know whether he did, but the minimum coating rod is needed, I think that would not be superfluous. So as imparting color, will counteract the formation of rust.
At the site of the author, as he wrote in the previous paragraph, on the welded handle, be placed rubber grips for hands.
For this point the author gets 3 out of 5 points.
analogs
Grade 5 of 5
At the present cases, the sale of a large number of different drills, as well as manual and motorized for drilling deep holes. Do counterparts there, as suggested by the author, in the form of nozzles on the screwdriver?
I was very surprised when I found it on sale, because I thought that drill, and especially screwdriver can not drill the hole.
It turns out that the blogger deserves the maximum evaluation at this point, since it was able to offer quite economical idea that the characteristics do not differ from the purchased analogues.
There is such an analog in the store about 60 thousand. rub.
Total
According to the results of our survey, this tool is gaining 16 points out of 20 possible.
