    Expert Review

    I’ll have to admit it; I’m a sucker for innovation. This Rockwell sander is a very unique design, specifically created to reduce vibration, thereby reducing fatigue. The pad is two-part, consisting of an outer ring around a central round pad. The two counter-rotate, directing the vibration into the workpiece, where it helps with the cutting action rather than into your arm, where it only helps make you tired. You can actually sand faster with this sander, than a conventional random orbital. The only problem is that you have to use their special sanding disks.

    This model replaces the RK4245K, making it the second generation of this technology. While I can’t say why Rockwell revised the design, I’d have to say that they learned from the first one and wanted to improve upon the design. I definitely approve.

    They’ve given this one a pad brake, which helps to eliminate any swirl marks and gouging when stopping, the most critical time. They’ve also installed a really effective dust collection system, which uses a cyclone air action to extract the dust into a plastic canister, rather than a cloth bag to filter it. The base is cast aluminum, to help guarantee flatness.Rating: 5/5
