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).

Rated 5 out of 5 by from Don’t know how I went without this for so long I decided one day that I wanted an oscillating tool and started shopping. I just wanted a cheap basic one Well the more I shopped the more I kept coming back to the F80 and that’s what I got I have used it for so many projects it’s unbelievable things I would have never guessed it is fantastic! The variable speed makes a difference and both have their place. All I can say is I will never be without one of these again.

Rated 5 out of 5 by from Best I've used!!! As a general contractor who tackles different kinds of tasks every day, this is my most valuable tool next to my brushless drill kit. The F80 is definitely the best multitool I've used, and I've used quite a few. An absolute time saver, easy to use, a real work horse. Only thing that would make this tool better is a better headlight. Rockwell customer service is also stellar, any issues I've had have been resolved quickly and easily. I've recommended Rockwell and the F80 specifically to all my fellow tool nerds.

Rated 5 out of 5 by from Works great This tool has become indispensable for jobs around the house. I bought the newer one and gave my older sonicrafter to my son I’ve used it on multiple projects. I gutted an older cabinet cutting through nails and wood and installed roll out shelving. Couldn’t have done it without this tool

Rated 5 out of 5 by from workhorse!!! I am a daily user of this tool and it really works great. Variable speed on this tool is excellent and makes a big difference depending on what type of project you are doing. Lately I am using it on an existing staircase to level the treads and I am also scraping up old self stick tiles on a hundred year old building in Chicago. So far so good.
