M12™ Variable Speed Polisher/Sander Kit

The Milwaukee M12™ Variable Speed Polisher/Sander Kit (2438-22X) is a compact 12V cordless tool that handles both polishing and sanding by switching accessories — two jobs in one tool. It runs on Milwaukee’s M12™ battery system and ships as a kit with accessories and a 1.5Ah battery.

What it does well

• Switches between polishing and sanding modes with a tool-free accessory change
• Variable speed trigger plus Dual Mode Control for finish work that needs a light touch
• Compact 12V form factor (2.8″ depth) that complements a full-size polisher for detail and tight areas
• Includes a 5-piece accessory pack with polishing and sanding pads

Is this the right polisher for you?

This is a detail tool. If you need to buff small panels, spot-correct paint, or sand in tight spaces without hauling a full-size polisher, the M12 fits. It runs on the M12™ system, so it’s a natural add for anyone already on Milwaukee 12V batteries. For large surface areas, pair it with a bigger polisher rather than relying on it alone.
