1 Answer
Answer This Question

A:  If it does I've never heard it come on. It does have plenty of cooling fins on top. I've never had problems with it getting hot at all.

      Terrible design
      The collet is designed so that to remove a bit you losen the nut until it pushes the collet open letting the bit come out. This us unnecessary and a pita. Mine is malfunctioning, the nut has popped off the collet completely and the bit is stuck in there with no way to get it out. My tool was used twice for a few minutes and is now junk. Thanks milwaukee!

        Need a battery die grinder
        I was going to buy this Milwaukee quarter inch die grinder, but after reading many many reviews I've decided that it's not worth my time and effort and money, it's a shame because I have other M12 Milwaukee tools that I love and have recently bought and have been missing out for years and it's a too bad that these straight or angle die grinders are a fail.

          3/16” collet size…
          Just got the 1/4” M12 right angle grinder in the today. Busted it out along with some batteries I order and played with the speed controller. Seemed great until I tried to drop in a 1/4” grinding wheel I use in my 1/4” air angle grinder and it doesn’t fit… I tried every but the only way to make it work is to barely have the collet nut threaded…very disappointed

            Worth Every Penny
            I purchased this grinder (tool only) back in April of this year to install an aftermarket rear bumper onto my Jeep. I decided to purchase this after reading countless reviews and watching numerous YouTube videos about it. I wanted it to make clean cuts in a tight spot of my Jeep's chassis. I chose this right angle grinder over the straight die grinder so I can use it as a metal surface grinder since this is mostly what I needed one for. I had two 6.0 batteries and only needed one for my specific bumper project (about 45 mins of continuous use). I personally feel that the 6.0 is a must with this tool but the cost of batteries and accessories adds up fast. I went to a local auto parts store and picked up a quick disc changer (aka twist lock) system, metal cutting discs, wheel arbor, and rotary burr set. With one new 6.0 battery (I already owned one previously), accessories, and tool I have around $300 invested. I have since used it on multiple projects (i.e. differential/transmission oil pan gasket removal, vinyl fence project, and a lot of miscellaneous small metal cutting and grinding projects). I am extremely satisfied in the overall performance of this tool. This tool feels really good in my hands (well balanced) and has enough speed and power to cut through thin metal and bolts, and grinding as needed. Thick metal cutting or high demand grinding I use a bandsaw or my m18 grinder. I love the fact that I do not have to drag out my air tools or extension cords anymore. I am incredibly impressed with electric tool technology and even more so in the Milwaukee brand. I own several Milwaukee tools and have not been let down by any of them and this one has been no exception. I am no longer a field service mechanic, so this tool will not get heavily used like my other Milwaukee tools used to so I cannot comment on longevity with heavy abuse. I am a advanced DIY'er and this tool is perfect for me and I highly recommend this for anyone else like me.

              This has to be the most useful tool i have now. As an automotive fabrication guy this is awesome. I have probably about 20 Milwaukee powertools now and this is the single biggest game changer that means i now no longer need airtools for anything, no more loud compressors in the shop, scratching paint with dirty air air hoses nothing. Thank you Milwaukee

              Expensive toy!
              With the two batteries that came with it I got a total of less than 20 minutes of work. While using the 2nd battery the charger wouldn’t charge number 1 because it was too hot.. When battery # 2 depleted # 1 was still too hot to charge... This has been consistent all day.. Additionally it seems the tool gets possibly too hot to function properly; no matter how light I sanded it would stop meaning release the trigger and start again too the point where you can’t get much done. To be fair when I started with the new tool & 1st battery it exceeded my expectations for that first 7-8 minutes. Hopefully I can return it, and get my $272 bones back!
