We recently took 26 corded and cordless oscillating multitool models and put them against each other to see what would happen. If you’re curious about how it all turned out, check out the full review of our Oscillating Multitool Shootout. As is the tradition around here, we’re taking a look at each of our individual contestants. Today, we’ve got our sights set on the corded Rockwell Sonicrafter F80 DuoTech Oscillating Tool. This 4.2-amp multi-tool has just about all the speed you could want for your cutting applications, as well as at least one feature that’s unique to Rockwell.
The Rockwell Sonicrafter employs what the company calls their Hyperlock Tool-Free blade change system. Basically, to change a blade, you’ll flip up the lever on the top of the tool. The lever, in the flipped-up position, acts as a hand crank that you’ll spin to unscrew the bolt that holds the blade in place.
The system works pretty well, and the blade feels secure in the bolt when everything gets locked into place. I still prefer the faster and simpler Starlock system that Bosch And Fein use, but at least this system won’t require a hex wrench to change out the blade.
The Rockwell Sonicrafter F80 DuoTech Oscillating Tool is right in the middle of the pack with its weight and ergonomics. It has a comfortable, but not extraordinary, handle with grippy overmolding. While Rockwell didn’t opt to design a narrow handle, they also didn’t design a brick for a handle either. In the end, we have a tool that feels good in the hand.
It weighs in at 3.31 lbs, which is just a bit heavier than the cordless Sonicrafter model. In the grand scheme of things, you probably won’t be wowed by the weight of the tool, but it also won’t cause you much grief because of how heavy it is.
This is the category where things start to get pretty interesting with the Rockwell Sonicrafter. For one thing, this tool features Rockwell’s Duotech Oscillation Technology, which revolves around a variable angle switch that allows you to adjust your cutting angle between 3.4° and 5°. The idea here is that you can choose between a tighter angle for more precise cutting, or a wider angle for faster, more aggressive cuts. There is something to be said for using a 5° arc for speed and power cutting, as the corded Rockwell Sonicrafter finished second in our speed tests.
I do have some concern that intentionally switching of the oscillation angle during use might damage the tool. I tried it, and it’s possible to do. It also gives a rather ill noise that makes me think it won’t be able to handle too many of these on the fly switches before something breaks. There’s enough resistance in the switch to keep it from flipping accidentally, so just avoid the “hey y’all, watch this” moment and you should be fine.
Because of how they work, oscillating multi-tools tend to vibrate a lot. These vibrations usually transfer to the user’s hands and can cause some discomfort on a long enough timeline. That’s why we appreciate a tool with some good vibration dampening technology. The Rockwell Sonicrafter does a decent job in this department. It won’t all but negate vibration like the Fein models will, but it also won’t send enough vibration up your arm to make your teeth rattle.
Just like vibration control, we appreciate some efforts put into noise reduction. After all, these tools tend to get pretty noisy, especially when you use them inside. This is one area where the Rockwell Sonicrafter really struggles. It registers as the second loudest tool while cutting (right behind Rockwell’s cordless model) at 103 dB. Part of this is because of the aggressive cutting action at 5°. This isn’t a deal-breaker, but be advised, you’ll want some earplugs.
This is another area where the Rockwell Sonicrafter oscillating tool really shines. For the whole kit, the corded Soncrafter will run you under $180. Sure, you can find a cheaper oscillating tool kit for less than that, but you probably won’t find too many that offer the feature set and performance that this model offers for the price.
Speaking of features, Rockwell checks all the major boxes here. You have a variable dial paired with the on/off switch instead of a trigger. They also include an LED light – something that most corded models pass on. Oscillating multi-tools aren’t known for a wide feature set and Rockwell doesn’t skip out on anything major.
Included In Kit
- RK5151 Sonicrafter Oscillating Tool
- Hard Case
- 10 Accessories for cutting, sanding, scraping, and polishing
The Bottom Line
The Rockwell Sonicrafter F80 DuoTech Oscillating Tool is a pretty solid machine from a company that doesn’t always make it into the Pro ranks. It struggles with its noise level and is average in the vibration category. From there, it sits at the Pro level for ergonomics, blade changes, and feature set with excellent ratings for cutting speed and value. If you’re looking for an oscillating tool that will set you back well under $200, the Rockwell F80 is worth considering.
