Rockwell F80 DUOTECH Oscillation Sonicrafter

Rockwell F80 DUOTECH Oscillation Sonicrafter

The new Rockwell® oscillating tool on the market today provides the option of two oscillating angles, 3.4 and 5.0 degrees. The F80 is the latest development in Rockwell’s evolution of oscillating tools. Dual oscillating angles enable the tool to work harder and run faster, while also providing industry breakthrough features such as HyperlockTM and true Universal FitTM.

The Sonicrafter F80 has a tapered, compact body powered by a 4.2 amp motor. Users now have the option of selecting the 5.0o oscillating angle when projects demand faster, more aggressive cuts with quicker results or 3.4o for continuous control.


“We challenge ourselves in developing products by listening to our customers in how the tools are being used and in what applications,” said Jeanne White, Rockwell’s Senior Product Manager. “With the F80 featuring two oscillating angles, users now how a choice of choosing the angle that best fits the application.”

Like the Sonicrafter F50, the F80 is five times faster than the basic Sonicrafter RK5121K. Both the Sonicrafter F50 and F80 feature the industry’s-best maximum cutting load of 35 lbs. of force. These tools can be pushed harder than any other oscillating tool before the blade stalls out.

Typically, by increasing the oscillation angle, it causes more movement and unwanted vibration. To combat this, Rockwell employed a counterweight inside the tools to offset the movement, and provide a smoother, more efficient cut.

Most oscillating tools have an oscillating angle of 3.2°. Rockwell’s fastest and most powerful Sonicrafter line expansion now includes the F80 (RK5151K) with oscillation angles of 3.4 and 5.0o, the F50 (RK5141K) at 5.0° and the F30 (RK5131K) at 4.0°. In addition, the oscillating tools incorporate electronic constant speed control that maintains the tool’s cut rate under load.

Rockwell pioneered Universal FitTM, the industry’s first true universal accessory system, which enabled Sonicrafters to accept other major brands’ accessories without adapters. Rockwell’s universal accessories are manufactured to fit all other competitive oscillating tools, giving consumers the option of using Rockwell blades and accessories without sacrificing fit or performance.

Sonicrafter oscillating tools feature a spring-loaded centering mount that positively engages accessories with the help of the HyperlockTM tool-less blade change system. Blade slippage and stopped cuts can be an issue with some manufacturers’ oscillating tools, so Rockwell introduced Hyperlock, a tool-less feature that provides one ton of clamping force to prevent accessory slippage. This is the highest accessory clamping force on any tool-less oscillating tool. Hyperlock is available on the new F80, F50, F30 and basic Sonicrafter model (RK5121K). It’s also featured on the 20V Sonicrafter (RK2863K).

Oscillating tools can handle a myriad of jobs and projects around the house and shop to save time, energy and money. However, a tool is only as good as the accessory doing the work. Several innovative accessories, including Rockwell’s line of Extended Life accessories are now available. The Extended Life accessories offer bi-metal teeth for added strength and durability.

    For a trade review this reads too much like an advertising brochure.

      Jack – It’s not a review…doesn’t say that anywhere. It’s a press release. We publish press releases on a regular basis, we also do reviews, but our Reviews are very clearly marked as such.
