The DCS356B pairs a brushless motor with a three-speed selector and a variable trigger, and it ships as a bare tool with two wood-cutting blades. DeWalt says a brushless motor delivers up to 57 percent more run time than a brushed one, which matters because an oscillating tool pulls steady current for as long as you hold the trigger. An LED lights the cut line.
Next to the SKIL PWRCore 12, the DeWalt has a larger 20V pack behind it, so it can cut longer through nail-embedded trim and sanding passes. It is the better tool for sustained cutting, while the SKIL is the better tool to hold in a tight cabinet. Compared with the WORX at 20V, the DeWalt has brushless efficiency and a bigger accessory market.
Ownership depends on batteries: because it is a bare tool, add the cost of a pack and charger unless you already own DeWalt 20V gear. Blades dull fast on nails and screws, so keep a few bimetal and carbide ones on hand. If you own the batteries, it is the strongest tool under the cap. Use the lowest speed for sanding and scraping, where a fast blade just melts paint into a gummy film, and the highest speed for cutting wood and plastic.
