Milwaukee M12 2531-20 Detail Sander: True 1.5mm Random Orbit Inside Tight Cabinet Corners

The Straight-Shooter Take

Trying to sand inside face-frame corners or intricate chair rungs with a triangle pad on an oscillating multi-tool is frustrating. Oscillating tools vibrate violently side-to-side, leaving ugly cross-grain swirl gouges that jump right out the second you wipe stain on the wood.

The M12 FUEL 2531-20 is a true orbital action detail sander with a tight 1.5 mm orbit diameter. It sands down to glass-smooth 220-grit in 90-degree corners with zero swirl marks.

Where It Earns Its Keep

1. True Orbital Action (Not Oscillating): Spins from 4,000 to 14,000 OPM with true random orbit motion for furniture-grade finishes.
2. Sub-2-Pound Ergonomics: Sits in your palm like a computer mouse, giving you fingertip touch sensitivity on delicate profiles.
3. Pneumatic-Level Low Vibration: Counterbalanced motor design means your palm doesn't feel numb after sanding 12 face frames.

The Annoyance

• Proprietary-shaped sandpaper delta sheets. Keep a supply of the official Milwaukee mesh abrasive sheets or punch your own from standard hook-and-loop rolls.
