Description
Product Overview
The WEN 20V Max Cordless Palm Sander (model 20401BT) is a compact, battery‑powered detail sander designed for precision work in tight spaces. Featuring a 5‑inch sanding pad with an angled nose, the tool delivers aggressive 80‑grit removal for fast material shaping. Powered by a 20V Max lithium‑ion battery (sold separately), it offers the freedom of cordless operation without sacrificing torque. The dual‑grip design allows you to hold the unit by the handle for stability or by the palm grip for maneuverability, while the hook‑and‑loop base pad makes sandpaper changes quick and tool‑free. Weighing just 2.16 lb (0.98 kg) and packaged in a compact 8.9 × 6.61 × 4.41 in box, it’s engineered for both comfort and portability.
Usage
Designed for woodworkers, hobbyists, and professional finishers, this palm sander excels in cabinet making, furniture restoration, and automotive interior work. The angled nose reaches inside corners and tight recesses where larger sanders cannot fit. Ideal for sanding doors, trim, and small panels, it also works well on metal and plastic surfaces when paired with the appropriate abrasive. Because it runs on a 20V battery, you can use it on job sites, in workshops without easy access to outlets, or in confined indoor areas where cords are a safety hazard.
