Key Features

Rockwell is unleashing the next-generation of oscillating multi-tools - a generation that is in a class of its own. With the unique Universal Fit System that accepts competitor's blades and the Hyperlock tool-free design, the Sonicrafter F80 introduces users to a speed of cut that is truly unrivaled.
Sonicrafter F80 Oscillating Multi-Tool - RK5151K | Rockwell Tools
The Sonicrafter's Hyperlock tool-free blade design provides 1 ton of maximum clamping force to prevent blade slippage & ensure your accessories are securely in-place.

Additionally, in order to ensure your tool won't bog down during cuts, the Sonicrafter was engineered with constant speed control for maintaining the speed-of-cut under load. The variable speed dial allows for optimal precision control, while Rockwell's patented Vibrafree counterweight offsets vibration for a smooth cut.
Rockwell’s unique Universal Fit System allows other accessories to fit tightly on our newly designed Sonicrafter. It doesn’t matter the brand, the model or the year purchased. No more driving across town to get the right blades.

Frequently Asked Questions

  • Does this come with a battery and charger?

    No, this model does not come with a battery or charger. This is an electric tool.

  • What is the Rockwell Sonicrafter?

    The Sonicrafter™ is a handheld multi-purpose oscillating tool designed for jobs that are too small or intricate for a traditional power tool, but too big for hand tools. The Sonicrafter is adapted for a wide variety of applications including sawing, sanding, scraping, cutting, rasping and removing grout. Variable speed control allows you to adapt to the demands of the project and materials.

  • I’ve seen some Sonicrafters promoted as battery operated, but this one looks like it has a cord. Is this battery operated or electric?

    The Rockwell Sonicrafter F80 is a powerful 4.2 Amp electric tool with a 10-foot cord to give you the reach you need to skip the extension cord.

  • How much does the Rockwell Sonicrafter F80 weigh?

    The Rockwell Sonicrafter F80 weighs 4.0 lbs.

  • Why is the Sonicrafter safer than other types of saws?

    Sonicrafter accessories move in a tiny back-and-forth motion just like the blades on medical grade saws used to cut off casts. The Microsonic™ action moves the blades and accessories side to side at an incredible rate of up to 19,000 oscillations per minute. It can easily cut through something as hard as a nail but won’t damage something as delicate as a balloon! Smooth-running oscillation eliminates kick-back, which is common to circular saws and similar tools, which have rotating blades that can grab or tear material and are difficult to control.

  • I saw that this Sonicrafter uses Duotech Oscillation™ Technology. What does that mean?

    While most comparable tools only have one oscillation mode, the Rockwell Sonicrafter F80 features two with Duotech Oscillation™ Technology. Mode 1 delivers massive power and a wider angle of blade oscillation. A narrower blade oscillation in Mode 2 is designed for precision and control.

  • How do I change the oscillation angle?

    On the body of the Rockwell Sonicrafter F80, there’s a switch near the head of the machine labeled “Duotech Oscillation.” Mode 1, or power mode, is the up position (5 deg.) and Mode 2, or precision mode, is the down position (3.4 deg.).

  • What accessories are available? Do I have to use Rockwell blades for the Sonicrafter F80?

    Rockwell offers a full line of Sonicrafter accessories for cutting, sanding, scraping and rasping, and grout removal accessories. With Universal Fit technology, though, you can use any brand of oscillating tool accessories on your Sonicrafter F80. No more driving across town to get the right blades!

  • How long do the accessories last?

    Rockwell Sonicrafter accessories are made of quality materials and designed to offer optimum performance for as long as possible. Actual wear rate will depend on the application, materials and user technique. Always use the accessory for its intended purpose, and allow the accessory to do the work without excessive force or pressure.

  • What is Hyperlock?

    Rockwell’s Sonicrafter F80 Hyperlock is a tool-free clamp technology that secures accessories with one ton of clamping force. Not only does it allow you quick accessory changes, Hyperlock keeps blades secure while you work without slipping.

  • What maintenance is required for the Sonicrafter?

    Keep the motor vents free of dust and debris. When changing accessories, wipe the accessory bolt and tool holder clean if needed. No other regular maintenance is required.

  • Is the Sonicrafter weatherproof?

    The Sonicrafter is made with professional grade materials and can be used outdoors, as long as it is not exposed to water or moisture.

  • I misplaced my manual. Is there anywhere I can get more information?

    You can download the manual here. You can also check out our Rockwell channel on YouTube for reference, or our friendly customer service team will be glad to answer any questions you may have at 1-866-514-7625 (ROCK).

Sonicrafter F80 4.2 Amp Oscillating Multi-Tool is rated 4.7 out of 5 by 70.
Rated 5 out of 5 by from A must have tool Probably my favorite tool ever. So many uses. Excellent quality, and a great protective carrying case

Rated 5 out of 5 by from I bought this to remove a shackle on my pickup. The F-80 allowed me to work in tight space and RW8963 blade cut through a 1/2 in steel bolt. Great tool and blade

Rated 5 out of 5 by from One of the GREATEST Tools EVER! After intro, I kept thinking, WHY? Why would I ever want it. So, I waited and waited and waited and finally I had a job where I need to do a flush cut multiple times so I purchased the Sonicrafter. Now? Well folks, I do not know how on earth I have existed for 75 years without one of these tools as you can do almost anything with them and once you have it, then your eyes are opened in front of you and if you do things around the home, you will reach for this tool nearly every time you are doing something at your home Then, once you buy it, keep your eyes opened every where for the TOOLS on sale to save money on the tools. Trust me, you will understand once you own one how great these things are. The only thing I have not figured out how to do with it is drill a hole but I am working on it. One more thing, while you are at it because if you don't buy the top model when you first buy one of these, you will regret it so go ahead and get the top of the line model so you can do more! I would recommend this tool to any and all of my friends without hesitation. I am a Quality Control Engineer and I do not hand out 5 stars to anyone because I can always see room for improvement, until, that is, I got to this tool and it got 5 stars in all areas.

Rated 5 out of 5 by from My favorite tool! I’ve owned two now. The first I bought at least 10 years ago and it was heavily used...and probably abused. Bought this one last month and I’m positive it will go a decade too. If not, I have solid trust in Rockwell. You won’t find a more diverse tool capable of multiple jobs.

Any suggestions for blade exchange, mine is stuck, can't unscrew the top or bottom without a wrench/pliers?

Asked by: hotinfl
The removal of the blade for the Rockwell Sonicrafters differs from one model to the next, depending on if they have the Hyperlock mechanism or not. If there is a bolt present that secures your accessory, then the bolt may simply be removed by an Allen key. Otherwise, you will need to flip over the lever on the top of your tool so that you can see the "lock" and "unlock" symbols underneath the lever, near the top. Push the upside-down lever as far parallel as it will go with the tool, then turn the lever counter-clockwise many times until the bolt at the bottom of the tool falls out. This procedure will allow you to change the accessory from your tool by placing the accessory where the bolt was, clamping the bolt on top, and turning the lever in a clockwise rotation to secure the accessory.
