Overview
The DEWALT DCS578X2 is a 60 volt cordless saw built around a 2456 watt motor spinning at 5800 RPM, with a 7.25 inch cutting capacity. At 8.2 pounds it is sized like a full size circular saw rather than a compact trim saw.
The 60 volt platform pushes more power through the motor than standard 20 volt cordless saws typically manage, which suits the 7.25 inch blade capacity aimed at framing and general construction cuts. The X2 kit code usually pairs the tool with two batteries, worth confirming on the listing since that affects total kit price and weight.

Who it's for

Performance notes
A 2456 watt motor at 5800 RPM on a 60 volt platform delivers more sustained cutting power than typical 20 volt cordless saws, matched to the 7.25 inch capacity for through cuts in dimensional lumber. The high speed steel build listed for the tool adds wear resistance over standard steel.
