The Specs seem to indicate that this tool is variable speed. Can someone please confirm that? ...

Asked by johnny August 6, 2018

Answers

This is not variable speed. It has one speed, 6600 rpm. It hasn’t been a problem for us because we always run at max. speed to be the most productive.

Can it run a tile or masonry diamond wheel?

Asked by skippy May 31, 2018

Answers

Absolutely. I have a 7 inch diamond turbo blade in it slicing concrete and old asphalt like butter. I recently sliced through 25 feet of old asphalt drive with just two batteries.

can this grinder also use standered 4 1/2" and 5" grinding wheels and blades? is this grinder more powerful and does it have higher rpm then prev fuel

Asked by PaulPhilly July 18, 2018
4
Answers

Using a smaller wheel would be a lot less productive. I use 7 inch cutoff blades and it flies through hot rolled steel. I use it to cut rebar all the time. It takes approx. 5 seconds to leisurely slice through number 4 with no effort, which is 1/2” diameter rebar. This grinder is a lot more powerful than the smaller 4-1/2” fuel.

Can you put a 7" / 9" diamond wheel on this and cut through concrete?

Asked by bigDog August 28, 2020
2
Answers

thanks for the reply Milwaukee. I saw that cut off saw as well, and it's cool, but I'm cutting in a tighter area where the cut off saw might not work well. It's a horizontal cut in a concrete wall closer to the ground level. So, that's why I will probably need this 9" angle grinder instead. So, is it ok to put a 9" diamond blade on this and make a horizontal cut into a concrete wall? I'm assuming yes, but just wanted to be sure.

Can I use a dry core bit with this grinder ?

Customer review from milwaukeetool.com logo
grinder works great I hate the guard these guards wobble while installed there not very well made for the guards or how the guards attach i was told by unicoa because there a authorized service center that its a common problem with all the grinders and if i send it to milwaukee tool myself they would of send it back and not fixed it because there nothing wrong with it so that upsets me for the price of this grinder milwaukee should of done a better job on the guard and how it attaches as well as the attachment peice is what wobbles which makes the guard wobble its a pore design and you should expect better quality from milwaukee i will be going back to my dewalt flexvolt grinders since the guards work well and don't wobble

(What's this)
This is a large grinder for serious work. I have a smaller rat tail grinder (corded, of course) and this Milwaukee grinder makes that one look like a toy. It takes a 9" grinding or cutting blade which can do a lot of work and can do it fairly fast. The grinder is large and uses a typical milwaukee battery. The battery does a good job of balancing the tool. It uses a typical Milwaukee charger, which has space for both an M18 battery and the smaller, triangular shaped M12 batteries. The lithium-ion battery charges fast and lasts a long time. It only comes with one battery, so you have to plan for that - either with a new battery or with the end of the day in mind. The guard adjusts easily with the push of a button on the edge. There is a lock on the trigger to prevent inadvertant use. The side handle screws into the body of the grinder, and it can be easily switched from one side to the other, depending on the user or the application. The bag is a little big, but it has plenty of space for additional blades and grinding discs, as well as "stuff" - gloves, glasses, other hand tools. I keep a complete set of jobsite extras in the bag, just because of the space available. I have a set of gloves, an extra tape measure, eye protection, a flashlight and a safety vest. There's plenty of room for that and more. Overall, it's a great tool with lots of power, made for large jobs / projects.

This kit comes with M18 FUEL 18-Volt Lithium-Ion Brushless Cordless 7/9 in. Grinder 2785-20 one REDLITHIUM High Output HD12.0 battery pack (48-11-1812), one M18/M12 multi-voltage rapid charger (48-59-1808), 9" Type 27 Wheel Guard Assembly, (49-12-0020) one 5/8"-11 FIXTEC nut, (05-59-0015) one Type 27 Backing Flange, (43-34-0825) one spanner wrench (49-96-0002) one anti-vibration handle, and a large contractor bag with shoulder strap. Everything about this grinder seems super-sized. The 12.0 Ah battery, at 3lbs 5oz, weighs twice as much as my XC5.0 batteries, and is an inch longer and taller. The rapid charger charges M18 batteries 40% faster than my old M18 chargers. The assembled grinder with battery weighs a hair less than 12 lbs. It's balanced for use with the 12Ah battery. The safety switch is part of the trigger assembly - just push forward to release the lock then pull up up to activate the trigger. It can all be done with one finger. The grinder runs at a fixed 6600 RPM and has a soft start feature. You'll want to use hearing protection - I measured 97 dB sound level at arms length with the grinder running but not using it to grind anything. The FIXTEC nut used to fasten the grinding disc is new to me. It has a semicircular folding handle so the nut can be tightened or removed without tools. If a tighter connection is needed the included spanner fits two holes in the nut that are exposed when the handle on the nut is lifted. I really like the grinder guard. It installs and adjusts without tools. The guard can be rotated in 30 degree increments by pressing the release level and turning until it clicks into the next detent. This FUEL grinder lives up to the Milwaukee FUEL brushless reputation - tons of power and good battery life.

“This thing is a monster”!! Those were the first words out of my husband's mouth when he unpackaged this Milwaukee M18 FUEL 7 / 9 in Large Angle Grinder. It is a LARGE, heavy-duty, powerful angle grinder of contractor grade quality. Definitely made for big jobs. It even comes with a shoulder strap to help bear the weight. Most remarkable of all, it is cordless. It will run on any Milwaukee 18V battery. The 18 V battery supplied with this kit is big and heavy. . Unfortunately, this all inclusive kit did not come with any discs. Those ordering online need to be made aware of that. Lots of us can't just run into town and visit the hardware store. The grinder was designed for 7-9” discs but can be used with a much smaller 4.5” disc. This is a Milwaukee product and that is where my confidence lies. We are satisfied owners of several Milwaukee products and do not hesitate to highly recommend all things Milwaukee.

I haven't used any of the other full sized battery powered girders out there but I can say with certainty, this one is a beast. The Grinder is well balanced, the grip is comfortable, and the quick change make a convenient tool even more convenient. The dust screen was easy to remove and clean. The trigger lock is easy to operate but still prevents accidental pulls. All and all its a good design. I ground about an 1inch off of a sidewalk slab and a 1/3inch off a second. It cruised maintaining a good speed even with a heavy wheel and a heavy load. For both lips I ended up using about a half a battery. The brake which wasn't even advertised is great. It slowed a wheel in seconds that on my old grinder that would have spun dangerously for days. If you were in a shop all day with a cord this is probably a little pricey but for my needs and considering I wanted the battery, it's perfect. I have to admit that right after I ordered it I though do I really need to spend the cash on this...? After taking it for a test spin the buyers remorse was obliterated as thoroughly as the cement I was grinding.

Nice for feild/outside work
Very good grinder. Nice to use where ever you need to without having to drag a cord. The only thing is it's hard on batteries when using the 9 inch wheels. Wire brushes, and the 7 inch wheels are not a problem. Don't use anything under the 6 amp, or you will swap out batteries fast.

I have a solid 12hrs of use on this grinder so far and I’m impressed with it. That said it is worth it to buy at least the 6Ah batteries or pick the kit version of this up. I chew through a 6.0 in about 20-30min of use with the grinder. 5.0 10-25min haven’t tried it on anything smaller yet. The super charger is also a worthy must in the long run to keep up battery charge with usage
