    Rockwell RK5140K Sonicrafter "died and went to hell" after only the second task...
  

*by M***E on Reviewed in the United States on July 27, 2013*

After reading all the positive reviews from fellow Amazon customers, I purchased the Rockwell RK5140K on 4th June 2013, and I received this unit on 14th June 2013.I used this oscillating tool only twice for a short period of time, and it stopped operating within the first five (5) minutes of the 2nd task today (26th July 2013). Thus, after only  43 days it "gave up its ghost!"I was unpleasantly surprised about that short-lived tool!!! Hmm, I should have known better with products that are "Made In China"...I normally avoid anything labeled "Made In China," but after reading all the positive reviews about this tool, I thought that it might be all right... It seems as if I were wrong with that assumption!Is there no quality assurance protocol in the Chinese manufacturing plants???I miss the good-old days of "Made In Germany," and "Made In U.S.A.!"The once common attributes pride and quality have been replaced with greed and quantity!!! With this mentality mankind is doomed!I shall contact the Rockwell Tools-customer service within the next few days.I shall update this review after the return of my repaired Rockwell RK5140K Sonicrafter through the service department of Rockwell Tools.Update (31st July 2013):On 29th July 2013 I called Rockwell customer service (866-514-7625) to utilize the warranty. The customer representative Mauricio, who was polite and helpful, entered all the necessary information in regards to my Sonicrafter X2 into Rockwell's database. He informed me that I would receive a return label for my defect product and that I would receive a replacement unit.All right, let's see... --So far so good...Update will follow.Update (13th August 2013):--So far so bad...2 weeks have passed, and I have not received a return label from Rockwell yet! Hmm, what is going on?I am going to call Rockwell again.I called Rockwell customer service, and I spoke with Robert. He verified my information and informed me that a return label had been sent off on the 9th August, which I should receive within the next few days. He said that he would send additionally a label via e-mail to me. Update will follow.Update (1st September 2013):16th August 2013: I received the return label from Rockwell.17th August 2013: I dropped off my parcel with my defect Rockwell RK5140K Sonicrafter at the Fedex store.I was pleasantly surprised when I received the Rockwell Sonicrafter replacement on the same day. What a coincidence!I tested the Rockwell RK5140K Sonicrafter replacement, and it was functioning flawlessly. Hmm, hopefully, it will be a keeper this time...I increased the star-rating to 4 stars, which I may change --either up or down, according to the performance of this machine.Update (4th November 2013):Oh, I forgot to mention that not only did I receive a new replacement unit from Rockwell, but I also received a whole new storage box with different attachments (blades) with it. Thus, I have two storage boxes and two sets of attachments... Super!!! I am a "happy camper" now!

I'm the kind of buyer who leaves "customer reviews" to those salts with more ambition and time than I, so let it be known: the Rockwell Sonicrafter 5140 finally motivated me to write one myself.In short, the device is FANTASTIC and does exactly what it claims, and probably more.In long, I bought it for an odd project that had frustrated me for years with an unsure approach:  a brick fireplace with a nice wooden mantel... merely nice, not great.  Close inspection showed it was once a plain, simple treatment of 3/4" hardwood surrounding the hearth.  A previous homeowner grafted a more detailed unit of columns, trim, and other details on top of that.  This layer of added interest was narrower than the layer of boredom beneath, so the boredom oddly framed the columns on all sides, thwarting their intent.  The effect was utterly baffling, yet the construction was so sturdy I opted to leave well enough alone because I couldn't find a ready way to flush-cut the offending old trim.  I could have easily done this with traditional tools if I removed the entire mantel but, um... no...  Lest my attempts to remove it instead net its complete and utter destruction, along with cratering the fireplace and hearth and house and street... ahem.  I considered using a circular saw until moldings and other obstacles suggested I review the previous sentence, oops.  Friends suggested I build a proper mantel myself... but I still kinda liked what was there, just wished I could make it better... so why wastefully scrap it and spend money buying more wood and tools and such to replace what I already had?My subconscious apparently spotted an oscillating tool at a big box store, because with no prior experience or knowledge of such things I felt my dim mental night light fizz on one day.  After reading several Amazon reviews, I retained some reservations but gained enough cautious optimism to place an order.  I went with Rockwell over competing manufacturers because of their Universal Fit feature, as I *hate* proprietary consumables.  Knowing my typical (ab)use of tools and the scale of this project, I sprang for the 5140's beefier 3 amp rating.I rarely geek out on power tools since I mainly just want the basics to do the job, but after 20 minutes I was in lust with this thing.  In an hour I flush cut the bothersome edges off that mantel - 10 feet of solid 3/4" oak - and then finish sanded the remaining edges to boot.  Yep: the Sonicrafter solved in one hour an issue that had bugged me for years (yeah, first world problem but so is everything on this site).  I look back on countless other projects it could have greatly improved and wish I'd bought one years ago; it's gonna be a short-reach go-to item now on.That said, my newbie experience bore a few things you should note:- The unit is well-made, solid, and quality built.  The tool-less head is a breeze to use, and the directional adjustments for blades, etc make it very versatile for tight spots and situations.  It is comfortable to hold, stable while running, and reasonably ergonomic - it's not sexy, but it works and hey, that's actually pret-ty sexy.- The unit is quiet enough for what it is - a high RPM power tool - but once the saw digs in, loudness amplifies by orders of magnitude.  Have earplugs handy, especially if you're working in a small enclosed space where acoustics reverberate.- You're used to sawdust being coarse and gritty... almost chunky?  HA!  This bad boy's oscillations produce a delightfully fine wooden mist.  I had no idea wood particulate could be rendered so minutely.  So wear a mask, and be prepared for cleanup!- Some reviewers claim this unit runs hot, but mine never did and I wasn't wearing gloves either.  Yeah so I'm an idiot, but the point is: just let the tool do its job! Don't force it, or try willing it to be "faster" by shoving it into the material.  You presumably bought it to save time - how much faster do you want it?- The included wood/metal blade works well, but I picked up a wood-only blade - its coarser, longer teeth worked immeasurably better (insert favorite knife/butter metaphor here).  I did encounter a few hidden nails, which a swap to the metal blade quickly dispatched.  Switching blades took only seconds thanks to the "Hyperlock" (dumb name, great feature).- Speaking of blades, Rockwell's blades are incredibly durable.  As the mantel was applied to brick and I was in for over 10 feet worth of plunge cuts, striking the masonry beneath - not once but many times - was inevitable.  Sure, the fine points of the teeth did chip and wear, but under this severe duty (abuse) they still lasted the entire job.  The useful markings stayed legible and the paint never wore off.  (I do wish an adjustable depth stop attachment for the head was available; meanwhile, patience is your friend).- The sander works as well as (probably better than) my old B&D Mouse, but like that other tool the pads can get gummed quickly.  Eh, so does regular sandpaper.  But you can't clean sandpaper; I was able to de-gum the pads a couple times.- The storage case is a nice, thoughtful design: no frills, but sturdy and compact.  I like the detachable lid with its little cubbies.Bah, I just typed "cubbies" in a sentence so there you have it - my first Amazon review and an hour I won't get back.  Hopefully it was worth it - I won't be making this a habit but I might be finding more excuses to use this wonderful, wonderful tool!

I picked this particular brand and model of oscillating tool because of it's special features. Not only does it have variable speeds, but it has a universal fit system that lets you use any of the brands of blades you can find locally. It has a no-tools blade lock also, so you don't have to worry about losing a special wrench to tighten the blades. Everything you need to lock in the blade is part of the tool itself.This one is a bit more powerful (3 amp motor vs 2.5 or less on most others) than most of the others available on the market. That means that it will be less likely to bog down when cutting into materials and also that it can cut a bit faster than the less-powerful ones.Because of the feature set on this tool, I would have bought it over even the more expensive brands like Fein even if the prices were the same. Rockwell is known for making quality tools, so I expect a long life for this, especially since I won't be putting it to professional use on a daily basis.If you just want an oscillating tool, don't mind about how much power it has, don't mind being locked into a certain brand of blade attachments, and don't mind keeping track of the tool you will tighten the blade to the tool with, get yourself a cheaper one like one of those Harbor Freight Tools sells.Rockwell makes a lower-powered version of this one that has the same universal fit, no-tools mounting system, and also one that is even less expensive that doesn't have the special mounting system.If you're going to put this to a lot of hard use, you might as well get this particular model. You'll save time changing blades and won't be inconvenienced if you need a replacement blade but don't have Rockwell blades for sale close to your home. Just buy another brand and lock it in place on this tool, and go to work!
