Questions & Answers

Can this be used as a sander?

Asked by: Yubaokie
yes but make sure you install the small filter on the outside of the grinder down by the battery interface. It will really rock with a sander wheel installed. If you use the paddle-type sanding wheel, make sure you use the correct (deeper/taller) guard. The instruction sheet that comes with the grinder explains it well.

Will this work with compact 18v batteries?

Asked by: RogerD
I use it for light wood work and a normal m18 2.0 batter is sufficient. Ex: Sanding wood using a 100 grit abrasive wheel. But for longer, intesive usage, I feel at least a 4.0 and higher is better.

Is it possible to use with a wire wheel ?

Asked by: OldTimer
Yes but make sure the wheel is properly rated for speed; the grinder runs at 8500 RPM.

What is the difference between the reg 18v battery grinder an the fuel 18v grinder?

I just bought the reg one not knowing about the fuel model and would like to know what makes the fuel better. As I do a lot of heavy grinding. And need the best of the best.
Asked by: matt
The Fuel is brushless motor technology. I don't know the torque detail on the grinder but on the cordless drill, the torque difference is about 50% versus the non-Fuel. I think. The brushless also helps on run time. If you do a lot of heavy grinding, I think you'd be measurably ahead to get the Fuel version. I have the 18V Fuel grinder, hammer drill (gen 1) and 7 1/4" circular saw, all really great tools. Get the 9ah battery if you are a heavy user, you'll want the juice as the grinder has a pretty good current draw.

I bought the grinder primarily to sharpen blades on a heavy duty 7 foot mower pulled by a 70 horsepower tractor. The blades are really difficult to remove, so just easier to prop the mower in the up position and crawl beneath to sharpen them. The grinder is very powerful yet easy to handle in the tight quarters I have to deal with. Way easier to use than the big corded Milwaukee I have. When I get to use it in under normal conditions (standing up), it is a pleasure to work with. It likes to consume battery power, I have a couple 4ah and a 9ah batteries which represents way more juice than I normally need. You will generally want to use the handle for best control. If you need a grinder, buy it.

I needed a powerful cordless grinder for wood working using carbide wheels and other cutting discs. This one is very good. It Dug into lot of tough wood and there is no slowing down. the best part is that it is cordless. I like that there is no lock on switch and I consider it a safety feature. I like the power consumption management of the M18 line, esp. brushless models. I can strip/sand a 4 ft log with just a 2.0 battery . This means less charging in between work.

I purchased this because i already had a battery that came with my circular saw. i paired it with a 9.0A battery and it gave me roughly 30-45mins of grinding time. Really made workflow much easier without have to worry about all he wires crossing the floor. It feels sturdy, and a little heavy but adding the 9.0 battery you will notice additional weight.Though its nothing that won't really hinder you and you'll easily get accustomed to the weight.

Of course it was a day and night difference. I like buying old made in the USA tools and restoring them. This grinder is super convenient and powerful for my restoration projects. would highly recommend. There is a switch-lock version too so for those fellas/ladies that don't like the paddle switch you won't miss out.

Rated 5 out of 5 by from Top of the line cordless tools This tool gets the job done and gets it done right. Battery life on this tool is amazing. Milwaukee has really come a long way with their brushless technology I don't waste my time looking at any other cordless tools. Keep doing what you're doing Milwaukee it's all good.
