Question: Can you tell me why the model # is different from one listed on Rockwell site? There's is RK2522K2 and states 3 year warranty. Is this the same tool?
Document: I have a woodworking company that uses this type of tool a lot. None of them are great (with the 12v batteries at least), and this one does better than most (Dermal, Rigid etc). I have used it for about 6 months now and while the batteries don't last a long time, they do an adequate job most times.Considering the Rockwell battery replacement warranty, I am quite pleased with it and would buy again unless a more favorable tool hits the shelves.
I got it and it worked fine for a hour or so while recharging the batteries. I didn't do any extensive work, just cutting a plywood board. Then one battery died completely! It was still chargeable but dead with the tool. The other battery still worked. When I contacted Rockwell customer support they told me they can't change the battery on general warranty and they could just send me another one based on their lifetime battery warranty where I had to pay handling and shipping. So I returned the item to Amazon.
The charge only lasted maybe 15 minutes then after only 3 days both batteries failed. I was deployed when I bought it back in September now 5 month later I am unable to return it and the lifetime replacement expired after 90 days from purchase. No one carries these special batteries either. The good news story is that I contacted Rockwell directly and they are standing behind their product as well as honoring the life time battery replacement program. I am happy again.
I have used this tool for so many different little projects. I found others that were $30.00 more in price but the Rockwell is made well and I love it.
I bought this unit brand new, on clearance, at nearly 70% off my local hardware store. I had not seen a cordless oscillating tool before, but had heard good things about the Rockwell Sonicrafter corded model. I wasn't sure what to expect and was honestly a bit concerned about the battery size and deep discount.My concerns about the price were gone after I tried the unit.
I liked this little tool so much i bought one for my brother in law this year. Invaluable when you have a tight space that is too big for a sawsall. This definately will not replace a sawsall. Works fantastic for cutting out electrical boxes in drywall, undercutting door jambs for flooring, flush cutting anything, etc. Solid construction, light on the end, lifetime batteries, its hard to beat.
You cannot hold an object in your hand and just cut it. You must clamp it in a vise!Batteries last up to a half hour, so keep the other battery charged while using the other one. The front LED light will flash when the battery needs replaced. Charging usually takes about a half hour too. Use the purchaser's Lifetime Replacement Warranty when they go bad!The only con I have is the blade attachment hex bolt setup. The blade always moves around while tightening with the Allen wrench.
Have another saw and was very disapointed with it have purchased a fair amount of rockwell tools which am happy with ! Was looking for one of these as use it for a lot of small jobs price was right and I am happy !! !
Both batteries work fine and also the tool. So I upgraded my star rating from 3 to 4. There is still the service issue and quality control is obviously not perfect. Anyways, it's a nice toolkit and worth the price!
one battery can cut through about 4or5  1x4's and thats it for wood. not too impressive. the infomericials always show it cutting nails. bull. the nail must be made of a soft metal or you just spent $15 cutting a nail cause the balde is ruined. a little dificult to tell if the nail is soft or not when in the wood. so dont think your going slicing through nails. still at $150 or less it worth the things that can be done with this thing.
Answer: yes
