Rockwell RK5140K Sonicrafter Hyperlock with Universal Fit and Constant Speed Control Oscillating Tool Kit

My wife and I decided that this would be an early B-day gift for me. We recently sold our house to purchase the home of our dreams. We new that the new house needed a lot of work. Our new home is a rustic-modern timber framed house. The construction of the house is very odd and difficult to work with. There was an electrical issue in one of the walls and unfortunately, the walls have wood cladding instead of sheetrock. The problem with this is that the walls were covered with wood plank first, then, the floor was laid. I did not want to damage the wood and slate tile floor when I was ripping down the cladding. I needed a tool the could cut the cladding flush with the floor. The Sonicrafter was purchased for this sole purpose. It did a fantastic job! Since then I have used it to aid in ripping out old skylights, altering door jambs, sanding door edges, making custom trim pieces for windows, and even used it to fix a barn door. We got it for one job yet have used more than I thought possible. The price vs quality is spot on and the ability to use other brand's attachments makes an already versatile tool even more versatile. The case it came in is sturdy and easy to work with, and the attachments are great starters. It has sped up my workflow seven-fold. The five star rating takes all this into consideration. I highly recommend this product if you need a multi-tool at an affordable cost.

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!

Being a wood worker and metal worker I had seen these Oscillating Multi-use Tools around but never thought much about it until a friend was helping me replace a sliding glass door. During the replacement job, he mentioned he had this little tool that would make the job much easier. After he returned with his multi-tool, I instantly became amazed by this little tool at how user friendly and useful it was. I decided on the spot that I must have one for myself. Upon doing my typical research on these tools, I found that the Rockwell model RK514K fit what I needed and wanted perfectly. With it 3.0amp motor, the fantastic case it comes with, the look and feel of the tool and the good selection of extra blades it comes with made it a great deal. If you've never used one of these tools, get one or borrow one to try out from a friend. They work so good at hundreds of job uses, from cutting or trimming almost anything to sanding in hard to reach places, they are light weight, full of power and very durable. If you ever try one, you WILL buy one. They are what every DIYer needs in their collection of tools and they are really rugged.

The sanding and cutting tool works great although the decibels are way up there. You definitely need ear protection. You must be careful when applying pressure as the sanding pad developed wear in a relatively short period of time which caused sand paper to not adhere as well and become less effective. Two new sanding pads were ordered for future use.

You need to get an oscillating tool; if you're on the fence about that, get off of it and buy one. You won't regret it. I looked around at all of them, and for my money, this was the winner. The Hyperlock System is the main reason: It requires no key, it secures the blade tightly, and it accepts all other manufacturers' blades. Now I'm no contractor, so longevity and ability to withstand abuse are not big issues for me; for those guys, maybe you want to go for the Fein as they have a reputation for that sort of stuff. My issues are cost, convenience and function. The cost of blades at $15 a pop can add up quickly; with the Sonicrafter, you can shop for the cheapest blades and be sure that you can get what you need when you need them. So, if you're in a bind on a weekend and can't wait for a cheap online blade to be shipped, at least you know you'll be able to get a blade from whichever store is open and not have to worry about them carrying "your brand." I've read about complaints of other brands getting too hot to handle or being too loud. Well, I wouldn't not buy a circular saw because it is too loud; these are power tools, what do you expect? In any case, the Sonicrafter is apparently quieter than most. Mine hasn't heated up, but I'm not running it for longer than, say, 30 seconds on a cut. But again, the reviews say that it is cooler than the others. And then there's the feature that causes the motor to adjust its speed as the cut gets more difficult, as well as the manually adjustable speed, not available on all brands. This baby has it all. The question is how did I ever live without it?

I bought this tool to replace a cheap version available at a tool discount chain store. The cheap version had many problems with the blade fastening system. It also burned through blades like crazy because it was a single speed drive. I was amazed at how much better I like using the sonicrafter. It is quieter, more powerful and easier to hold on to. The blade change system is well thought out and works beautifully. Not having to reach for a wrench to change or re-tighten a blade is more than just a convenience. The blade lock system is also compatible with every brand of blade that I have tried. Sometimes you don't have a choice of blade, you just need one now. It is nice to know that just about every blade does fit. When I bought this tool, my wife asked why do you need that now that the project is just about done. I find that I am reaching for the sonicrafter more often than just about any other power tool (other than my drill/driver). I have used it for demolition to cut nails where I didn't want to risk damage the wallboard on the other side of the studs, cutting off the header and base of the wall where I was expanding an opening, cutting thin sheet metal ductwork to length (that was amazing, better than a shear), and for match cutting of notches in wood to "let in" a cross member. This is a great tool and worth the difference in price over the bargain brand version.

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!

I do a lot of handyman work around my house, and I also like tools. I read about all the other sonic tools out there, and what sold me on this one as opposed the others is: this one has a case, and it accepts all other brands attachments. The power tool I use most is my drill, and the other ones come out about once a week or so. Within one week of owning this tool, I used it 5 times in one week for 5 different tasks. I'm really happy with it. It's easy to work with, the case is pretty cool, and it just works really well. I'm very happy with it. I did read pretty much about every other "sonic" tool on amazon, and this one had the most consistent high ratings, came with a case, had a long cord, and was very reasonably priced. You won't know how much you need this tool until you get one. I find reasons to use it quite often. I'm very happy with it.

The Rockwell Sonicrafter is a great tool. I've used it a couple of times now and love it. Its great for those awkward cuts you have to make. I haven't tried any other manufacturer's cutting discs so I can't comment on the universal fit capability. It is constructed very well and is quite light for its size. It is a little bigger than i thought it would be but not enoug to make it hard to handle or anything. All in all i would totally recommend this tool!

Came on time. Works well. Takes some getting used to. Seems good quality.

Fits any tools, any brand and better then my MasterCraft.

very versatile tool. does exactly as promised.

excellent product i use it since i bought it. The job done quickly hard to cut position on door frame. No complaints.
