Milwaukee M18™ FUEL 21mm Random Orbital Polisher Obsessed Garage

Welcome to the big leagues. Milwaukee’s M18™ FUEL 21mm Random Orbital Polisher is a cordless beast I’ll be looking for reasons to use. So, please excuse the excitement you’ll hear while reading this, but I am super pumped about this polisher and the M18™ FUEL 15mm Random Orbital Polisher we sell.

First, let me mention the power behind this tool. Many of you are familiar with Milwaukee’s batteries and how efficient they are – especially with running an orbital polisher; you want the best in the business fueling your tools. 

There are so many things to love about this machine, like the quick application time. If you have a larger vehicle, a boat, RV, or even a plane, this polisher was built to tackle those larger applications. It has a 6” backing plate covering 30% more surface area. You want to be careful because it heats paint more quickly than its baby brother (the 15mm).

One of the key features of this machine is that it doesn’t bog under pressure, so it can maintain its speed under load, making for a better user experience and more efficiency compared to its competition.

This is the machine you want when tackling polishing and heavy-correction applications. It strikes a balance between application speed and the risk of surface damage if you’re not careful. Again, this is a pro-level tool, so do have a solid understanding of using an orbital polisher of this magnitude. 

I love this thing and will likely use it more than anyone on the planet.
