The DeWALT DCS355N oscillating multi-tool is designed for sanding and sawing tasks where compact size and maneuverability matter. It delivers up to 20,000 oscillations per minute, powered by an 18V Lithium‑Ion battery platform (battery sold separately). Weighing approximately 1.06 kg and finished in DeWALT's yellow and black colour scheme, the tool is intended for both trade professionals and home improvers who need a light, portable sanding machine for a variety of materials and confined spaces.

How to use

Fit the appropriate oscillating accessory for the sanding or sawing task, ensuring the tool is switched off and the battery is removed before accessory change. Insert a charged 18V battery and secure it according to the manufacturer's instructions. Start the tool at low speed to position the sanding pad or blade, then increase speed as needed up to the maximum oscillation rate for efficient material removal. Apply light, steady pressure; allow the tool's oscillation to do the work rather than forcing it. After use, switch off the tool, remove the battery and store both tool and accessories in a dry place.

Recommendations

Use appropriate personal protective equipment such as eye protection, dust mask and hearing protection due to the sound and dust levels. Select grit size and accessory type matched to the material and finish required. For prolonged sanding work, use dust extraction or a vacuum attachment where compatible to reduce airborne dust. Avoid excessive side pressure to prevent accelerated wear of accessories and the tool.
