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 F50 introduces users to a speed of cut that is truly unrivaled.
Sonicrafter F50 Oscillating Multi-Tool - RK5142K | Rockwell
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.

Rated 5 out of 5 by from Sonic Crafter I've owned this tool since they first came out. Excellent for close precise work. I've ordered spare blades and they are of the original quality every time. Nice tool to have.

Rated 4 out of 5 by from Replacement of a previous model which went bad. This model was a replacement of a 3.0 model which went bad. Have only used this new model once, but it performed well. Used it to sand portions of an exterior deck I was restaining, where I could not access with my belt sander. Have not had to use the cutting attachments yet, but with the power noticed, it should work out well. I do have to say that I was very impressed with the service I received when inquiring about having my previous model repaired/replaced. Very friendly, professional and, quick. I have not had this kind of service with other tool manufactures and Rockwell should be proud of the people working for them.

Rated 4 out of 5 by from Does the job Rockwell replaced a unit that broke . They stood by their product and displayed out standing customer service. The tool works as specified but if it's like the last one , it gets louder and vibrates more as it is used. Note I only used the last unit 10 times to trim a wooden door frame when installing tile. I used it to cut some dowel plugs flush in the shop.

Rated 1 out of 5 by from will not stay tight Sorry I can not give it a good review. I The bolt and flange will not stay tight, I have went through quite a few in the years and it is disappointing to try and do work. So I bought a quick change model (different company) with a spring loaded tool holder and am so much happier. Wish SoniCrafter made a adaptor to do this. Would not recommend model.
