Milwaukee M18 Polisher Review Best Cordless Power Tool for Automotive Buffing

Description

Performance and Power of the Milwaukee 2738-20 M18 Polisher

I tested the Milwaukee 2738-20 M18 18-Volt Fuel Lithium-Ion Brushless Cordless 7 inch Variable Speed Polisher extensively on various automotive surfaces, and I have to say, its 2200 RPM variable speed really stands out. The brushless motor feels robust, providing the kind of power usually expected from corded polishers but with the freedom of cordless convenience. The 18mm stroke gives a smooth polishing action that’s effective in removing swirl marks and oxidation without overheating the paint. Holding this polisher felt natural despite its 7.54 pounds weight, and the power delivery was consistent, allowing me to tackle paint correction and finishing tasks with confidence.

Handling and Ergonomics

The design of this cordless polisher impressed me more than I anticipated. Its size, about 18.5 x 7.5 x 5.5 inches, fits comfortably in my hands, enabling long polishing sessions without excessive fatigue. The materials used, a mix of plastic and metal, give it a sturdy yet manageable feel. The variable speed trigger responds smoothly, letting me dial in the perfect speed for each surface. I noticed my coworkers appreciated how quiet it was compared to some corded models we’ve used, which made working indoors less stressful. However, the balance shifts a bit when attaching larger pads, something to keep in mind if you prefer heavier buffing accessories.

Battery Life and Run-Time Considerations

One of the most attractive features of this tool is its battery-powered design, harnessing Milwaukee’s M18 lithium-ion technology. Although the battery itself isn’t included, pairing it with a fully charged M18 pack delivers impressive run-time. I pushed it through demanding tasks and noticed it maintained power without noticeable drops. The absence of a cord means I could move around the garage freely, which was a significant convenience during multi-car projects. Still, users should prepare with backup batteries for extended work, as heavy use drains the battery faster than lighter polishing jobs.

Versatility and Settings

This polisher shines in its versatility. The variable speed control lets me switch between gentle finishing and aggressive cutting without changing tools. The 7-inch backing plate accommodates a wide range of polishing pads, from foam to wool, adapting to various detailing needs. I experimented with several compounds and polishes, and the tool adjusted well, handling everything from light swirl removal to deeper paint correction. While it’s primarily geared for automotive use, I found it handy on other surfaces, such as fiberglass and gel coats, making this device a multi-purpose champion in my toolkit.

Benefits

• Cordless design with brushless motor delivers high performance similar to corded models
• Variable speed up to 2200 RPM enables precise control for different polishing tasks
• Lightweight and ergonomic for comfortable handling during extended use

The Milwaukee polisher’s strengths are clear in these features. It combines power, flexibility, and ease of use effectively, which is why it frequently comes up in conversations among detailers I know.

Drawbacks

• Battery not included, so initial investment can be higher if you don’t own compatible packs
• Heavier than some competitors, which might cause fatigue with prolonged use
• Balance affected when using larger or heavier polishing pads

These negatives don’t overshadow the tool’s capabilities but are important to keep in mind depending on your specific needs and budget.

Alternative Offerings

Comparing this polisher to other popular models like the DeWalt DWP849X or the Makita 9237CX3, it’s clear that Milwaukee’s model excels in cordless convenience and motor technology. The DeWalt offers strong performance but is corded, limiting mobility. The Makita has a similar stroke length but is heavier and lacks the same battery flexibility. Milwaukee’s M18 battery ecosystem is a huge plus if you already own Milwaukee tools, allowing for seamless battery swaps. However, price-wise, some competitors offer slightly lower upfront costs but may fall short in run-time and brushless motor efficiency. This Milwaukee polisher is a strong contender for those prioritizing cordless power and variable speed control.

Price Performance

Considering the features packed into this polisher, I find the price to quality ratio quite favorable. It’s not the cheapest polisher on the market, but the brushless motor, variable speed control, and cordless freedom justify the cost for serious detailers or professionals. The tool’s compatibility with the M18 battery platform adds long-term value, as the batteries can power multiple tools, spreading out the investment. If you’re looking for a reliable, cordless polisher that handles demanding automotive jobs without compromise, this tool offers smart spending benefits, especially if you already own or plan to invest in Milwaukee’s battery system. However, casual users might find the price a bit steep compared to entry-level corded models.

This product has definitely earned its place in my workshop through a mix of power, portability, and thoughtful design, though it’s not without its trade-offs. The Milwaukee 2738-20 M18 Polisher is a solid choice if you’re chasing professional-level results with the advantages of battery-powered flexibility.
