Stand out
The Milwaukee M18 FUEL 18 Volt Brushless Cordless 4 1/2 - 5 in Angle Grinder with paddle switch was a great upgrade from my non-FUEL Milwaukee 4 1/2 - 5 in. Angle Grinder. I have been using the brushed version for the past year and a half but felt I needed more power and runtime. The FUEL version stepped up to the plate. Has been instrumental in stripping paint/rust/scale from a few metal restoration projects that I have been working on. The added power and extended run time using High Output 6amp batteries has saved me a great amount of time. The paddle switch is easy to use after a short learning curve if you haven't used one before. Definitely recommend.

Very Convenient!
I love this grinder! The power is there, it’s quiet, great feel in your hand. I personally use this for quick cuts or prepping for welds. It’s awesome not having to find the nearest power outlet and bring out the extension chord, you have this and saves you so much time and hassle getting set up and time is money. Very often you find yourself not anywhere near a power outlet or they’re being used up, this saves you from having to wait to plug in or when there’s no power at all. Obviously if you’re doing some heavy grinding, you might want to consider the chorded because who wants to burn through batteries? I find this my first choice over my Milwaukee chorded grinder due to just being so convenient. Great choice here!

As with all Milwaukee M-12 and M-18 tools this is an excellent product. I have many Milwaukee red lithium tools and love them all.

This grinder set came with a charger and two 18 volt, 6 ampere hour batteries, a wrench for removing and installing the wheels, and a carrying case. It does not include any grinding or cutting wheels. This grinder is fast, versatile, and powerful. I have only had it for a little over a month and have already used for multiple projects. It is perfect for sharpening cutting tools. It makes quick work of sharpening rotary lawn mower blades or things like your garden hoe or manual lawn edger. I have also used it for grinding down weld beads and for grinding the heads off of rivets for some disassembly work. It makes quick work of those activities too. With a diamond edged blade I used it for cutting up a batch of steel channel and some heavy sheet metal to manageable sizes for a salvage operation and for cutting the heads off some rusted bolts. I expect it would also work well for cutting auto body panels. And with a masonry blade you can also cut concrete, concrete blocks or bricks. Its versatility is further enhanced by being battery powered. Are you working distant from an electrical source? Just grab it and go - no need to find an electrical outlet or drag an extension cord around. This grinder is designed for use with five-inch stones or blades. There does not seem to be as much selection available for five inch attachments as there is for the more common 4-1/2 inch sizes, but I have had no difficulty finding the stones and blades that I needed. According to the instruction manual that came with the grinder, it can also be used with the 4-1/2 inch stones and blades if you purchase the optional blade guard for the 4-1/2 inch stones or blades.

An angle grinder is one of those tools that once you have one you want a couple more. In most cases when I am using an angle grinder I will be preforming multiple functions. Grinding, cutting, cleaning with a wire wheel or smoothing surface with a flap disc. Multiple grinders allow you to set up for multiple functions saving time and energy in the shop. I have 2 - 4 1/2" corded grinders and still find myself changing wheels more often than I would like. This cordless Milwaukee is the first I've owned with a paddle switch. This took a little getting used to but I like it. When you let go of the switch it stops, the disadvantage is you must hold the switch, there is no switch lock. It is also heavier than my corded grinders, this is in part because of the 6 AH batteries. I found battery life to be excellent. I cut up some scrap metal for recycling then was away for almost 2 weeks. When I returned I tested the tool doing some grinding, smoothing with a flap disc and cleaning rust with a wire wheel. This was all on the initial charge and the battery showed 50% charge and the tool was running well. My only negative comment was there is no on tool storage for the wrench. This feature is on the cheapest grinder I have and it's great, you always know there the wrench is.
