What Is a 12 V Spot Polisher / Detail Sander?
A 12 V spot polisher / detail sander is a small, cordless tool that combines the functions of a polisher and a sander in one compact unit. The “spot” / “detail” name reflects that it’s made for finer work — polishing small areas, correcting swirls, sanding and smoothing tight spots, finishing work on panels, and getting into corners where full-size polishers or sanders can’t reach.
These tools are especially useful for automotive detailing, small woodworking tasks, repair work, and anywhere you need precise control in a small form factor.
One strong example is Milwaukee’s M12 Spot Polisher / Detail Sander, which switches between sanding and polishing modes.
Key specs from that model:
- Two speed ranges:
• Polishing mode: 0–2,800 RPM
• Sanding mode: 0–8,300 RPM - Compact size: 130 mm length
- Weight: ~0.7 kg
- Tool-free accessory change (you can swap pads and heads without tools)
So, a good 12 V spot polisher/detail sander is small, lightweight, has variable speeds, and can switch between sanding & polishing.
