Tool part number 194689 A39AF Purchased to replace Hitachi 10.8V for roof construction. First impressions are very positive. Minus - the price (although a good tool for a lower price is very difficult to find); cartridge quality. Additions after a year of work: A large number of revolutions is good, but not always: I work at the 2nd speed both for drilling and for tightening screws, and because of the high revolutions, it often breaks bits (you need to get used to such power). For a large amount of work away from electricity, I advise you to take it with a 5A battery, because. two 2A batteries may not be enough for a day. After several falls (albeit from a small height, about 2 meters), he remained intact. The cartridge clamps the bits very badly (it constantly spins and the bit flies out). To tighten it well, you need to make a titanic effort. Although, for example, drills of smaller diameter clamp well. Due to my own inattention, when working next to the chain-link mesh, the wire from it climbed into the vent. hole, thereby badly crippling the impeller. After that, the sound of Shurik operation changed and the air flow for cooling decreased. This impeller changes along with the engine, button and flashlight, so be careful!
