I admit something. Although I was a fairly "skillful" guy working in house construction in the early 70's, I never really thought about how great "impact wrenches" are for easily driving and loosening large bolts. I did this with my regular old hand drills and it worked and I thought that was it. it was easier to nail up the windows (and there are LOTS of windows in our house) 2x4 and plywood with an impact wrench that all the "helpers" I hired brought. It became clear that drills were more for drilling and impact tools for driving and loosening screws. It was something of an epiphany for me as I thought I had all the necessary tools. Apparently not. The most amazing thing about using an impact wrench is that it's so gentle on your wrist; It doesn't spin like a drill as the staccato hits are very fast. It also means you don't have to work hard to keep the screw from breaking. But I've also switched to Torx screws and left out Philips heads because they enhance the effect; With large Torx screws and an impact wrench, everyone gains new super power. So I wanted to get one but didn't want to lose a lot of money because I would only use it occasionally. The Revain actually had an unnamed shock driver with a test and charger for under $40 when I first checked, and it was probably a great deal. even if it is not currently offered. After looking around I decided that the specs of this impact wrench would fit and third party replacement batteries are readily available. Why take a station wagon? Because the combo only costs $10 more than a single impact wrench. (The drill included in this kit is pretty basic: fewer clutch adjustments, lighter build, only one speed (but adjustable by trigger). Nothing fancy and not as good as my existing B&D 18V NiCad tools. (Note that one can go for ebay and buy an adapter plate to run these tools with these 18v lithium batteries although I don't really see much need the difference between 18v and 20v is not just minimal in numbers, but actually 20v lithium batteries are about 18 volts under load (lithium is a bit lighter and has a bit more chance of catching fire, so it's a small thing for me.) Anyway, the last storm is right now over and I went out to remove some boards over the front doors Impact wrench was cute Huge big screws came out of deep wood with almost no effort Where has this thing been all my life The umulator be necessitates many hours of battery life. I ordered a quick charger along with a pair of third party 4Ah spare batteries. Of course you don't have to do this. A slow charger works well if you don't mind being "slow" and is probably actually better for your battery. Maybe just a "man thing". I don't want each of the large batteries to take a full day to charge. I give this one 4 stars for starters and will update as I use it. But my first rating is "cool", seems to work the same as the more expensive ones. It didn't get the last star because it felt less ergonomic in my hand than the $200 models I've tried. Do you have a percussion instrument?
