DeWALT DCS781N-XJ katkaisu- ja jiirisaha

With a 305 mm blade spinning at 3800 rpm, the DeWALT DCS781N-XJ delivers clean, fast cuts across framing lumber, trim, and moulding. This 54V XR FlexVolt brushless sliding mitre saw runs cordless for total jobsite freedom, yet its cutting capacity rivals corded models—up to 305 x 85 mm at 90°/90°.

Overview

The DCS781N-XJ is a bare unit, meaning battery and charger are sold separately. It belongs to DeWALT's XR FlexVolt platform, sharing batteries with other 54V tools. The brushless motor provides efficient power delivery and longer runtime per charge. A sliding rail system extends crosscut capacity while maintaining a compact footprint. The saw weighs 23.2 kg and stands 450 mm tall, balancing stability with portability.

• Dual bevel (49° left/right) and mitre range (50° left, 60° right) for complex compound cuts.
• Wireless Tool Control (WTC) pairs with compatible dust extractors for automatic activation.
• 35 mm dust extraction port keeps the work area cleaner.
