The simple key to drill their own hands: that is hard to lose

Drill in our time have virtually everyone. With this helper can without any effort and hang up the shelf, and for example, a stool repaired. And I think that at the mere word "drill", each of you will remember the key to change the drill bit. So small and not very comfortable. And if he loses, then repair just stopped!

In this review, I would like to introduce you to a simple invention, which can be made with your own hands. (How does this work will show at the end)

**The hero of our review, the key is to drill their own hands**

On a review of the key for drill chuck with your hands. I'll do for you the analysis of this instrument, and perhaps my review will help you understand whether such a device is needed or not.

Idea

Grade 5 of 5

As I have said, there is a drill almost everyone, and I am no exception. I use it quite often and, of course, almost every time you have to change the drill bit with a special key. Personally, I use this key is not very convenient: a small handle and uncomfortable in the hand. In addition, it is easy to lose.

The main tool for this with his own hands - an ordinary wrench

The author proposed the original idea as possible with their hands out of the ordinary key for drill chuck to make a handy tool.

Design

Evaluation 4 of 5

tool design is very simple. It is based on an ordinary wrench jaws between which is welded threaded part of the bolt with a nut stranded. And one of the faces of welded standard key for drill chuck. Thus the key together with the nut can be rotated from side to side.

Clipped bolt with a nut inserted into the wrench

Frankly, I do not quite understand why the author did a movable connection between the key for drill and wrench. I think if you weld the key holder to the wrench without the use of nuts, the use of such a tool would be much more convenient, there will be nothing to hang. For this author received from me 4 points.
