I am a seasoned DIY'r and do most of the maintenance and upgrade of my older house with my wife's valuable help. Through the years, I have used 4 different oscillating tools, all from well known manufacturers. I purchased the F50 a couple of months ago when I began reconstructing grandma's 20x20' deck (lots of demolition work). I have also used it for other outdoor work at her and my house. I find the F50 to perform as advertized, especially when coupled with the newer Bosh carbide blades with which I cut through deck nails without any fuss. It is so powerful that I have the sense that the speed of cutting is mostly limited by the blade. In dimensional lumber, the 1 5/8" usable depth carbide blades sink completely with little effort. Paying some attention, I was also able to cut some rough but acceptable joints. It is less noisy and more stable than every other similar tool with which I have worked. The blade change mechanism is very convenient and decisive, and there are applications where the variable speed is a definitive plus (in general, lower speed = more control and less friction). The price is more than right, especially if (like me) you buy it during a sale (less than $100). The F50 feels like a very mature tool with all the power and convenience necessary to competently perform all the jobs for which it was designed, which makes it a real pleasure to use. I would wholeheartedly recommend it as one of the most useful, smaller power tools to have in the tool box.

I have this Rockwell F50, and I wouldn't have believed how remarkable this wonderful tool is, it's fast and very effective on the job, TIP if you run it a slower speed less heat build up on blades it will last much longer, because they are not exactly cheap...

I shopped for a multi-tool for myself, a DIYer homeowner, and for a Xmas gift for our professional (low-voltage specialist / installer) son. I have a cordless (Craftsman 12v) already, and we both wanted a high power corded unit that we wouldn't have to buy $80 batteries for! I looked at 5 different tools, bought 4 & handled them at home. Purposely did not look at the Boch, or Fein because they were priced higher than budget.
Looked at Makita because they are dependable and well made, DeWalt for same reason, Porter Cable, Rockwell & Dremel (because he had suggested that was what he wanted). After reading all kinds of reviews on various sites and handling them, I kept 2 to give him the choice ... this 4 Amp Rockwell F50 Sonicrafter & the Makita TM3010. After looking at them both, he agreed with me that the Rockwell stood out for many reasons. I have since been using my Rockwell around the house for various projects, from some metal cutting fitting cabinets into a wall (wood/drywall), to grout removal on the bathroom floor. This really GREAT! The following is a general Pro/Con, but also some comparison to the Makita which is also a very good tool, just not as good a value for the $$.

Pros: Very low vibration; Very low (relatively speaking) noise level; Superior multi-blade brand tool-less clamping, no additional disks needed for any brand blade; Clamp lever is very easy to work and fast; Well balanced in hand, easily held; Best power; Soft start gradually increases to speed; 2 LED lights, one on each side of head lighting cutting zone well; Moderately priced for features; 3 year warranty.

Con; Speed variable not as slow as Makita, runs 11 - 20,000 OPM. But this is a pretty minor point in my experience.

The Makita was the 2nd choice.
Pros: Best speed range (6-20,000 OPM); very low vibration; very low (relatively speaking) noise level; multi-blade brand tool-less clamping; well balanced in hand, easily held; good power; soft start gradually increases to speed.
Cons: It's blade changing mechanism is not as 'friendly' for quick change of ALL brands of blades like the Rockwell, requiring more work to loosen the lever and use of multiple clamp disks for different brand blades. Has no LED lights on head to light work zone; Cost more than the others; only 1 year warranty

For the value, I recommend the Rockwell!

I just bought this Rockwell sonicrafter F50 oscillating tool at Lowe's a week ago and I will be the first to say this is top of line and will go head to head with Bosch / Porter cable & FEIN in the top oscillating tool. This tool has tons of power and speed the way it cuts through 2x4s and 3/4" plywood is amazing plus if you seen the videos it truly cuts nails in less than a second. Also the Hyperlock tool-free blade Clamping force to prevent blade slippage and Universal Fit System is fantastic and I love the two lights on the sides so by this being my first Rockwell tool I am very impressed and if they make tools like this I will be buying more from them like the 4 1/2 circular saw real soon.

The Rockwell RK5141K 4.0A Sonicrafter F50 Kit with Hyper Lock and Universal Fit System is at the top of Rockwell's line of oscillating power tools. I have an older Rockwell Sonicrafter tool that I bought several years ago that works okay, but I never liked the fact that you had to use a special tool to change blades, and it also did not accept other manufacturers blades. The Rockwell RK5141K is leaps and bounds a much better tool as it does not require a separate tool to change blades, has a universal fitting system, has LED lighting, and has more power to boot.

The tool arrives in a very nice tool box that is perfect for storage. The box arrives with tight plastic straps keeping the top and two upper storage trays from popping open in shipping, which is great for keeping all of the parts in place but a real pain to try to get the box opened after purchase. I had to use a utility knife to cut the straps and a pair of pliers to get them out of the storage trays. Once the straps are removed, though, the tool box is easy to open and close and is great for storing the tool and extra blades. The set comes complete with some square cutting blades, round blade, and some sanding discs. There is a separate rod included to allow universal fitting.

The instructions that come with the tool are pretty much useless. It is a folded sheet of paper with vague information printed in about 4 different languages. At first I thought there were no instructions at all until I noticed some illustrations in a folded section of the paper that tries to illustrate how the tool is used. Even those are not very useful. So you don't have to spend time puzzling over it, there is a long bar on the top front of the tool. In its down position the bar locks the blade in place. To install or remove a blade you pull the back end of the bar upward and flip it over so it sticks out the front horizontally. You can then turn the bar counterclockwise, like a lever, to unscrew the knob from the tool that holds the blade or sanding disc in place. The knob can be completely removed if necessary to use the alternative rod for attaching different brands of blades or discs. Once you put the new blade in place you twist the bar clockwise to tighten it up and then flip the bar back down to its default flat position on the top of the tool. None of this is illustrated or explained very well in the instructions. The system is great, though, and allows for very easy blade removal and replacement without needing additional tools.

The tool has two LED lights at the front to light up the work area. This is a vast improvement over my old Rockwell oscillating tool. The motor is powerful and has no problem cutting through wood and metal. I am not a carpenter, but the included cutting blades and discs are more than adequate for my needs as a homeowner and woodworking hobbyist.

It is clear that Rockwell is trying very hard to make a name for itself in tools. The RK5141K has a very solid feel to it, comes with enough accessories to get you started on most any project, is versatile in that it can accommodate other branded blades, cutting discs, and sanding discs, and is priced lower than most other branded oscillating tools. The storage box it comes with is a nice perk and makes the entire package a very good value for homeowners and professionals alike.

Great Tool! I had one of the original Rockwell multitool- it was loud and a pain to change blades, so it sat unused and was eventually given away. This F50 is so much more a pleasure to use. It is a well-behaved Hoss of a tool. I also have a 12v PorterCable for small drywall cuts but this Sonicrafter comes out for any serious work. The only thing I would say negatively is that it does not accept all other brand blades as I had assumed due to it's description. Most 'universal' blades have notches at the 12:00, 3:00, and 9:00 postions but to work with the F50, there also needs to be (smaller)notches at the 1:30, 4:30, 7:30, and 10:30 positions. I have cut these smaller notches into some blades using a Dremel tool, but it is a little tedious to do. All in all I would highly recommend this tool- it is not too loud, doesn't vibrate as bad as the older tool, and is powerful. I am perfectly pleased with my purchase. The carry case is just bonus goodness.

What a fabulous tool! I've been an obsessive project person all my life, and I can't believe I didn't know this existed. But what a lifesaver. I am in the process of turning a disgusting little "room" that housed a water heater into a clever little pantry with a tankless heater mounted on the wall. After I got the old water heat out, I pulled off the sheetrock, and then tackled the floor, which was rotted down to the subfloor. But how to remove the floorboards?? they run outward to the kitchen, and I wanted to saw off the rotten ends at the doorway, but there's no room to get a skill-saw in there, and I couldn't use a Sawsall because I didn't want to destroy the subfloor. Presto, Rockwell Sonicrafter to the rescue. It just cut through those boards like magic. Think of an electric mortise chisel (or maybe an electric toothbrush). The blade oscillates back and forth so fast, it's like a tiny buzzsaw. Each cut into the old 1 1/4" floorboards took just a second or two -- the pictures give you a basic idea. So with this tool removing the old boards was a snap. Without it, it would have taken hours and hours of chiseling.

This Rockwell version of the 'multi-tool' seems really tough. It keeps going -- and cutting -- even when you lean all your weight on it. If the blade does get hung up, it has enough power to start vibrating YOU! The blade stayed sharp (even though the blades that come with the tool are not "extended wear." I was using it on Speed 2 out of a possible 5 speeds. One caveat is to tighten the gripper thingy fairly tight before clamping it down, or the blade may start coming loose. This is not apparent from the skimpy comic-book directions.

To see all the things you can do with a multi-tool, google 'Fein multitool,' but then come back and buy this Rockwell for 1/3 the price. Really, I don't see how it could be better than it is. And it has a 3-year warranty. This is my new all-time-favorite electric tool!

Wow!, what a great tool. I have had the Genesis which for the money is just OK. This Rockwell has several things going for it that sets it apart from others. The quick toolless blade change mechanism is a very nice design, and the blade is very secure using it. The variable speed makes using this on delicate work must easier, because in lower speed, you have less vibration, and noise, and it allows better concentration on the job. This kit is nice, but not really a reason to buy the tool. I buy my blades from other sources ,and they are not all the same, so this is not a review of the blades, only the machine.
It has a really long cord, I think about 10 feet. My first job was on Hardie board, and the regular steel blade sinks into hardie board very easily. It was doing great until I hit a nail and took a couple of teeth off of the blade. Never hit metal with a regualr steel blade unless you have spares, and it won't cut the nail no matter how long you wait, just don't do it. I used it for a minute or two at a time, and I never felt it get warm. I don't suspect it will ever get as warm as that Genesis did. This tool is top shelf, you can buy others that cost more, and might have a toolless design as well, but you won't find one that is as versatile, and a pleasure to use like this Rockwell.

I bought this to do a very specific project in a tight space; cut out the bottom of a custom bathroom vanity cabinet and replace the bottom. It worked perfectly. I was able to tightly control the path of the blade, cut flush against the back of the finished face, and the entire job took me less than an hour. This is honestly the best small power tool I have purchased in a very long time, and without a doubt the absolute best small saw I've ever owned.

For the money, hands down the best one I have used. I have used Fein, and Rigid, and this unit with all of the extras they give you works wonderfully. I work as a contractor and this tool is used for wood, tile, metal, u name it I cut it. Remember, you do not need to run this at full speed to make it cut,my blades actually last longer and cut faster at lower speed. in fact, until I learned that little fact, I not only burned up blades faster,but my wood as well. this machine has plenty of power even at low speed and does not hear up like other brands. I use it on every job to cut something where a sawsall will not fit.
