The Rockwell Sonic rafter F50 oscillating tool has raised the bar for the oscillating tool category. With the increased oscillating angle of 5-Degrees and the constant speed control, it's one of the fastest cutting oscillating tools available. Not only is it fast, but it can be pushed harder than any other tool out there with a Max Cutting load of 35 lbs. This results in dependable, best-in-class performance. The Vibrafree counterweight offsets vibration for smooth cutting. The Hyper lock tool-less blade change with 1TON of clamping force allows for easy blade changes and prevents blade slippage. The F50 also features an LED light, metal gear housing/metal Hyper lock lever and variable speed. Additionally, all Sonic rafter models continue to be the only tools that offer a truly universal accessory interface to accept any brand of accessories without the need for an adapter.
