Percussion screwdriver: I twist-twist, I want to help you

Mechanical and plumbing work is common,urgent and extreme. When the turn comes the last, masters, as a rule, swear on what the light costs. For we are talking about a problem that you can not solve so simply, moreover, you can ruin an instrument.Rotary screwdriver
For examples, you do not need to go far. Rusty screws and screws can not be unscrewed with a screwdriver without risk either ripping off the bonnet or ditching the sting and thereby damaging the tool. Another "abusive" case is the twisting of a highly corroded steel bolt from an aluminum part (and the pair "steel-aluminum" is known for its "love" for mutual boiling). It would be nice to warm the bolt, but not with every detail so you can do ...
However, in the arsenal of a locksmith there is a tool,Able to cope with the above problems: shock-rotary screwdriver. Its very name explains the principle of action: the transformation of the shock-forward motion into rotational motion.
Already the appearance of this tool inspiresrespect. The impact screwdriver has a chrome-vanadium alloy reinforced metal case several times larger than that of its "sister", and is designed for hammer blows. Actually, the dimensions of the case with the notches are made in such a way that the screwdriver can be kept inoperative during operation.
Impact screwdriverThe main "actor" is a bit, ornozzle, which the shock screwdriver transmits the energy of rotation. Nozzles, as a rule, come with it in the kit or are purchased separately. They are of two types: with a flat sting and cross-shaped. Nozzles are inserted into the connecting part of the square shape. On it, you can also fix the end keys. This allows you to use a tool for working with bolts and nuts, which is especially convenient for car mechanics.
For a shock screwdriver to beuniversal, it must have a reverse function. This is realized by the direction switch, which ensures the rotation of the screwdriver head with the nozzle both clockwise and anti-clockwise. The reverse function, firstly, allows the tool to be used also for the tightening of the self-tapping bolt or other fasteners, and secondly, by acting on the connection in the "twist-twist" mode, the most hopeless bolt can be released.
In how to use a shock screwdriver, there is noabsolutely nothing complicated. It is enough to set the desired direction of rotation on it, take it in the non-working hand, insert the tip of the nozzle into the screw / screw slot (or put the key on the screw head) and strike with a hammer on the screwdriver's end.How to use a shock screwdriverIn order for her body not to slip in the palm of her hand, she mustto be in the glove. The impact in combination with the rotation crush the rust on the screw. Once it is free and turns a few degrees, you should use the reverse function and make a few strokes. This should further free the thread of the fasteners from rust. The subsequent reverse in the majority of cases finally turns out the attached bolt or screw.
The impact screwdriver has long and firmly registered intoolkits of large and small shops, car service stations, in locksmith's workshops and in boxes of home craftsmen. The most perfect and high-quality samples, made almost always in Germany, do not have other reviews, except excellent ones.
