The is a compact corded random orbit sander built for everyday sanding tasks where control and finish matter. This thing doesn’t try to be fancy — it just gives you predictable performance whether you’re taking back paint or smoothing edges on plywood.

Under the hood it’s powered by a 250 W motor that spins the pad between about 7,500 and 12,000 rpm, plus an orbital motion that keeps the surface swirl‑free. That combination of power and motion gets the job done fast without burning through discs.

Key Features:

• 250 W Motor - Plenty of grunt for wood, lacquers, fillers and light metal sanding without bogging down.
• Variable Speed - Lets you dial in speed based on material — slow for finish work, faster for stock removal.
• Compact, Ergonomic Grip - Easy to hold in different positions so your hand doesn’t tire on long runs.
• Dust Extraction System - Built‑in microfilter box catches a lot of dust, keeping the work area cleaner.
• Hook‑and‑Loop Pad - Quick disc changes when you’re swapping grits on the fly.
