What Makes Milwaukee 2738-20 Standout?

Variable Speed Polisher/Sander

Variable speed dial is handy when it comes to the requirement of different speeds for projects. The Milwaukee 2738-20 features a variable speed dial conveniently placed on the tool’s spine for quick speed changing. With this feature, you’ll be able to adjust the speed between 0 to 2,200 RMP. The minimum rate you can choose from the polisher is 800 RPM, and the maximum speed you can choose from the tool is 2,200 RPM.

Cordless Full-Size Rotary Polisher

We all know the struggle of working with the corded tool; it keeps us in a range, and when the limit reaches, we have to look for a new socket or have to turn the whole project around.

Moving the project is not always possible, so a cordless polisher is a way to go.

Being cordless, the working range is unlimited. You will work freely; it does not tie you to the cord limit of 8-10 ft. And it’s also easy to move around with the tool.

Polishing RPM: 0 – 2,200 RPM

As we have mentioned earlier, it features a variable speed dial that you can adjust 0 to 2,200 RPM. This feature is useful when you need to turn down the speed for some touch-ups or need a high-speed for aggressive polishing.

The smoothness is excellent because the motor is built with pure materials for smooth speed delivery, so you can expect a flawless result every time you use the tool.

7-Inch Pad Capacity

Milwaukee 2738-20 M18 fuel 7″ variable speed cordless polisher accepts a polishing pad of 7 inches, which is sufficient for covering large vehicles and surfaces. The speed spreads out evenly for perfect polishing and doesn’t leave any marks.

Constant Power Technology

The constant power technology helps the Milwaukee 2738-20 m18 to deliver the speed of your choice and remain the same until you stop the tool.

Inefficiency is a common issue for many rotary tools. Let us break it to you in some short words.

The rotary tool delivers rotations from a motor that is inside of the machine. When the tool cannot provide constant power, it will decrease or increase the speed limit without users’ consent. If this happens, the tool will work at an uneven motion that can ruin the project. Hence, this device did an excellent job featuring constant power.

Paired With M18 XC5.0 Batteries

With the tool being cordless, it’s simple to acknowledge that the Milwaukee 28738-20 is battery operated. The tool uses an M18 XC5.0 battery that is capable of running it for several hours.

Delivers Corded Performance

When you think about battery-operated tools, it’s normal to think about the performance wise comparing to corded tools, when the 2738-10 polisher is capable of performing a corded polisher.

We have compared the tool with some other corded polisher that shares the same qualities, and we can say that comparing to a corded polisher, it did better, but the only downside of this polisher is that the battery needs to be charged for more use.

Total Control through a Variable Speed Dial and Trigger

As we have mentioned earlier, it features a variable speed control that can be adjusted. The trigger and dial are placed ergonomically for comfort and quick action. The tool stays in users’ control because of these two features.

Run-Time: Full-Size Car on 1 Charge

Well, it features an XC5.0 battery that is capable of finishing one big project at once. So, if you’re looking for a battery-operated polisher that will run for several hours, this tool is just for you.

Rubber Over-Mold Front Housing

Rubber over-mold front housing feature allows the user to grip onto the tool with maximum comfort. Let’s be real here; a tool that is not comfortable to hold or work with is useless here’s why.

No matter how useful a tool is, if it doesn’t feel comfortable to work with, the user will be unable to work with the tool with perfection. Features help the user for better results, but if the user cannot operate the tool, it won’t be run on its own.

Lock-On/Lock-Off Switch

Imagine, polishing a car and trying to cover every part of the vehicle while pressing the trigger, it’s too much of work.

Working with this device you don’t have to focus on the trigger anymore. The tool can lock the speed of your desire and maintain the momentum until you want it to stop.
