Rated 5 out of 5 by from I bought this grinder for 3 jobs, cutting & grinding stone, wire brushing metal railings & cuttin... I bought this grinder for 3 jobs, cutting & grinding stone, wire brushing metal railings & cutting metal. The big question for me, and I spend hours & hours trying to solve it, was does this unit use both 5/8" & 7/8" disks? Well after looking on the HD website using their search engine and seeing no 5/8" arbor 4 1/2" or 5" regular cutoff wheels for either metal or stone, I went to 5 different hardware stores & home centers including my local HD, wasting all kinds of time! Some of the stores had 60 different kinds of disks to choose from!... none had 5/8" arbor 4 1/2" or 5", but only 5/8" in the 4" size. The directions say to only use 4 1/2" or 5" wheels, so I was beginning to think why would Milwaukee make a grinder that you can't find wheels for? I even looked on line to see if there was a 5/8" to 7/8" adapter, which there is BUT, after looking at several blogs & Q&A websites, I found the answer! Come to find out this unit can take both! (see pics) Why in the world HD nor Milwaukee mentions this anywhere, be it in the instructions, the box or on the web is strange to say the least....it seems like a very important feature! The way it works is there is a little raised area on the bottom Flange that will fit 7/8" disk holes, 5/8" disks just fit right on the spindle shaft (see pics). There is no need to flip the Flange like on some grinders ( which is nice!). I also found the start switch lever that you need to move before pushing down the paddle on mine was sticking to the on position for the first few times I tried it. I would let the paddle go but the grinder didn't shut off. After going thru 5 or 6 cycles & manually moving the black switch back & forth, it's been working fine. You might want to try yours to be safe before actually working with the tool. I was quite shocked when I released the tool and it kept going full speed! I should also mention the the back of the Flange that faces the tool has 2 flat spots so make sure to rotate it until it seats fully on the tool (see pic) before putting on a wheel. While changing blades you need to take off the battery, but I found there are some sharp edges on the plastic case near where the battery slide on that will catch & pull clothes. I took a piece of 120 grit sandpaper to knock off the sharp edges (see pic) problem solved. If you are going to use this with a wire cup wheel, you'll need a 5/8" with 11 threads per inch, usually listed as 5/8" /11. I've read some places that say you can use a larger wire cup wheel than 5" without the guard, but I don't think that makes any sense, I remember getting hit with wire wheel fragments from using a drill mounted wire cup wheel which hurt, that's so much slower than a grinder! I found that the depth of cut with the guard on is just about 1" & with a 4" wheel and just under 1 1/4" with a 5" wheel. I used 2 cutoff wheels that worked very well with this grinder from the HD website. The first is a Whirlwind 4 1/2" blade for concrete, stone & brick, it can be used wet or dry. Model # THS 4.5 Internet #300801591 The other is a Milwaukee 5" metal/stainless cut off blade Model # 49-93-7810 Internet #301042332 Both come with a 5/8" bushing, but as described above you really don't need it. I hope this helps someone save a lot of grief & aggravation as the tool is really nice to use!

Rated 5 out of 5 by from M18 Cordless Grinder! Milwaukee does it again! They made an amazing tool that is perfect! The m18 grinder has some very nice features including : Cordless, Auto braking, easy to change blades, anti vibration handle 4.5 and 5 in capable, and a easy to move guard for both 4.5 and 5 in discs. I have been waiting years to finally own a cordless grinder. most time the corded grinders are a pain to move around with. This one is well balanced and easy to maneuver. overall if you are looking for a cordless grinder look no further! get this one!

Rated 5 out of 5 by from TORQUE!!! Miwaukee does it again. Time to throw out my Dewalt Grinder. I used the grinder this weekend to install closet kits. Instead of using the standard large wire cutters or a sawzall i used this. Put on a metal grinding blade and away i went. The grinder cut right through the wire shelving with ease. I used blue painters tape to eliminate the chipping of the coating. The M18 Line is awesome and highly recommended. I had 2 batteries from a Milwakee Impact Driver so the Tool-Only option is more affordable to most. When you first use the grinder the power it has is very easy to see. The torque is very evident as well. The shock absorbing handle comes in handy for all projects. Comes with 2 steel blade guards for 5 inch wheels a comfort grip brace handle, two removable filters for the tool. A great add to any man or womans tool collection.

Rated 5 out of 5 by from Potent and well made! This tool feels great to handle before you even switch it on. Solid with a well-built feel to tit. In the box is the main tool, a side handle, two guards (type 27 - grinding and type 1 - cutting) and a spare clip-on air filter. You bring your own battery and grinding or cutting wheels (4 1/2" or 5"). No tools are needed at all. The guards have a firm clip that releases them and allows them to be positioned in various positions. Changing the wheels is done by lifting a tab on the arbor and turning the locking nut by hand. The switch has a safety lever that prevents the switch from being actuated by accident, and believe me this is important. When the tool turns on you can feel the torque as it move the tool as it accelerates up to speed. The wheel stops pretty fast when the tool is switched off. The box says "under 2 seconds". Hard to time but it certainly is fast enough not to be running when you put it down. Needless to say, it grinds away very well. This is one of those tool with which you really must wear safety glasses. Proud to own one of these beasts!
