Milwaukee Variable Speed Polisher Kit

The Milwaukee Variable Speed Polisher Kit (2738-22) is an impressive addition to any professional or DIY detailer's toolkit. As someone deeply entrenched in both woodworking and automotive detailing, I had the opportunity to put this cordless polisher through its paces in a variety of scenarios. Here’s a detailed look at my experience with this versatile tool.

Design and Build Quality

Milwaukee is renowned for its robust build quality, and this polisher is no exception. The first thing that struck me was its solid construction. The rubber over-molded front housing is a thoughtful touch, ensuring that you won’t accidentally mar delicate surfaces. The tool feels balanced in hand, and the grip is comfortable even during extended use. At 6.4 lbs with a 5.0 battery, the weight is manageable, although it can become somewhat tiring during prolonged sessions.

Cordless Freedom

One of the standout features of this Milwaukee polisher is its cordless operation. Transitioning from a corded polisher to this model was a revelation. No longer tethered by a power cord, I found it much easier to maneuver around vehicles and woodworking projects. This freedom is particularly useful in confined spaces or when working on large surfaces like a boat hull or countertops.

Performance and Variable Speed Control

Performance-wise, the Milwaukee polisher does not disappoint. The variable speed dial and trigger provide excellent control, allowing me to dial in the exact RPM needed for different tasks. The polisher’s speed range from 0 to 2,200 RPM covers a broad spectrum of applications, from gentle polishing to more aggressive compounding.

I tested the polisher on a variety of surfaces, including automotive paint, fiberglass, and wood. It performed admirably in each case. The motor is powerful and maintains consistent RPM even under load, which is crucial for achieving a uniform finish. I appreciated the lock-on/lock-off switch for longer sessions, as it reduces hand fatigue.

Battery Life and Charging

Battery life is often a concern with cordless tools, especially for high-demand applications like polishing. The Milwaukee polisher runs on M18 REDLITHIUM batteries, and I used both the XC and HD versions. For light to moderate tasks, a single 8.0 amp-hour battery was sufficient to complete a full-sized vehicle. However, for more intensive jobs, such as compounding a heavily oxidized boat hull, I found that multiple batteries were necessary to maintain uninterrupted workflow.

The battery life varied depending on the intensity of the task. For example, high-speed, high-torque applications drained the battery faster, while lighter polishing tasks allowed for longer run times. It’s worth investing in extra batteries and a rapid charger if you plan on tackling large projects.

Practical Applications

As a professional tool, the Milwaukee polisher excels in a variety of settings. In an automotive detailing context, it made quick work of removing swirl marks and applying wax. The cordless operation eliminated the hassle of managing extension cords around the vehicle, and the polisher’s consistent power delivery ensured a smooth, even finish.

In woodworking, I used the polisher to finish countertops and deburr logs. The variable speed control allowed me to precisely adjust the RPM to suit the material and task at hand. The polisher’s ability to maintain a consistent speed under varying loads was particularly beneficial, ensuring an even finish across the entire surface.

Noise and Comfort

One minor downside is the noise level. The polisher emits a high-pitched noise, especially at higher speeds, which can be quite loud. Ear protection is recommended for extended use. Despite this, the overall comfort of using the tool is excellent. The rubber over-mold and the choice of handle options (U-handle and side handle) provide good ergonomics and reduce user fatigue.

Value and Investment

From a cost perspective, the Milwaukee Variable Speed Polisher is not the cheapest option on the market. However, its build quality, performance, and cordless convenience justify the investment for professionals and serious enthusiasts. The 5-year tool warranty and Milwaukee’s reputation for durability add peace of mind.

Final Thoughts

The Milwaukee Variable Speed Polisher Kit is a top-tier tool that offers a blend of power, precision, and cordless convenience. It is well-suited for a wide range of applications, from automotive detailing to woodworking. The ability to maintain consistent speed under load, coupled with the freedom from cords, makes this polisher a joy to use.

Would I recommend this tool? Absolutely. For professionals and dedicated DIY enthusiasts, the Milwaukee Variable Speed Polisher offers a level of performance and convenience that is hard to beat. While the initial investment is significant, the time saved and the quality of results achieved make it a worthwhile addition to any toolkit. If you’re looking for a reliable, high-performance polisher that frees you from the constraints of cords, the Milwaukee 2738-22 is an excellent choice.
