I bought my grinder when I was in a pinch and it didn't disappoint. Since then I've used it on several jobs and home projects and it always gets what I need to done. It has a sufficient amount of power while being easy to hold for control. My only downside is the battery dies rather quick, so only 4 stars; but since I have several batteries ready and charged at my disposal, it's not too bad.
Wow, I purchased my grinder set and was extremely surprised, not only did I get the grinder but also a bag, a charger and 2 20 volt max 6ah batteries, the kick plate is easily movable with the push of a switch, the handle is easily removed or relocated to the other side. Now my corded dewalt grinder is on the shelf. Wish that I could have posted a couple of videos but my camera was broken
I was a holdout for converting power hungry tools to battery power. This was probably because of poor experiences with a 12v Circ saw. Recently I added the 4-1/2” grinder to my arsenal of 20v tools, and it didn’t disappoint one bit. I use this mostly for cutting and grinding metal for fabrication and some automotive work. Bottom line is the battery never quit. I used this for a number of jobs throughout the day and the 6ah battery showed full charge. Near the end of the day I loaded it up for the torture test in the chop saw rig. It cut 3ft of 3/4” steel rod into pieces and never quit. Battery was still at 1/2 charge. Capacity is not an issue for this combination. The down side is that the tool is long. It is well balanced and handles well, the tool-less arbor nut is awesome. Also the guard has a tool-less mechanisms to move on the fly. For tight jobs i will still pull out ole reliable, otherwise this thing is my new friend.
This grinder is great I would highly recommend it to anyone looking for a cordless grinder. It is a battery eater though but its not surprising or a problem with hard hard this thing works. Its a beast. Pros: brushless, the switch safety is easy to use, it does not bog down easily it will grind and cut like crazy, the brake works nicely, it has a nice hand feel and ergonomics, and it uses an allen wrench for the hold down nut instead of those pin wrenches. Cons: The screw in handle is horrible its just plastic and cheap feeling, the case near the exhaust gets hot, the intake filters clog pretty quickly and you have to remove a screw to get them off, and there needs to be a holder for the allen wrench that removes the hold down nut.
I have another 20Volt Dewalt grinder but it has a single finger trigger, I like the paddle switch better when i have to use it for extended periods of time and now that its cold it is easier to operate with gloves on compared to the trigger. There is plenty of torque and runs for a good length of time. The only complaint i have for the paddle switch grinder is it is fairly loud for what it is.
I've been impressed with this grinder since I first picked it up. It has good balance and a natural feel. I have used it at work for two weeks. This grinder performs the same as my corded 4 1/2 dewalt grinder. I have been getting around 15 to 20 minutes of grind time using a 6ah battery. I put my flexvolt battery on it and got a bit more runtime. The paddle switch is a nice feature and there is less fatigue in my hand than other trigger styles. Sometimes I forget its a paddle trigger and lift my finger but the grinder doesnt stop till I relax my grip on the trigger. Still getting use to the tool I guess, but I like the feature. Also changing the disc is easier because the button is on the top, so I can hold the grinder and push the button with one hand and use the other hand to twist the grinding disc off. I am very happy with this tool as it meets and even exceeds my expectations for a battery powered grinder. I have the 6" flexvolt grinder and a metabo and after two weeks my hands are reaching for the 4 1/2 because of the lightweight, balance, ease of changing discs and enough power to do most job. I used a flapper wheel and a 3" wire cup. The wire cup surprised me as I was holding it one handed and had difficulties keeping it steady because of the power I wasnt expecting.
This is a tough lil grinder. I have had this thing a few weeks now, and i have given it a thorough workout. In the neighborhood of 30 hours of use. That my friend is a lot of battery charges. I judge this tool worthy. I was initially put off with this tool because it had a paddle switch, and I prefer a trigger, however Dewalt has made substantial improvements in the comfort of this tool. Anybody that runs a grinder for a living knows comfort is the key to good craftsmanship and low end of day fatigue. This thing has a tough motor so you don't have to feather the pressure to keep it going. The six amp hour batteries are also a great addition to those of us who work for a living and not doing weekend projects out of our garage. My lone gripe for this tool is lack of a dcb118 fast charger. Overall, this is s tough lil grinder that makes my job and therefore my life easier. Thank you dewalt.
