DEWALT DCG412B 20V MAX* Lithium Ion 4-1/2” Grinder (Tool Only)

Works well. I have several corded angle grinders, but this one allows me to take it to places with out electricity and I don't have to drag along a generator.

Amazing and convenient! We have always owned an electric grinder... for many years. We always thought it would be more powerful and would never "run out" of battery. We were happily surprised by how much power this battery powered grinder had!! It was able to complete our project, while using it all day long! We were cutting through rebar and thick metal horse fencing this time. I can't say enough about how nice it is to mot have a cord, and be constrained by WHERE we could use our grinder... it is freeing.

Reliability & performance are what I was looking for. So far, it has met both of those requirements. Will update as time passes. Would purchase again.

Really a great tool just what I was looking for

A little stupid, and not super powerful. It is clearly not a flagship unit, you can tell by how rough and unrefined the torque delivery is. But for me, I rarely use an angle grinder. I didn't need 60v, an XR, or anything over the top. It's easy to handle, and has good ergonomics. It takes material out with absolute ease, my only complaint is how unrefined it seems, very clearly not their primary concern of a tool. Plenty power for me though.

what you will hold in your hand is a grinder that is nothing short of the power it delivers comparing it to a corded tool. It spins @7000rpm; a bit slower than corded tool but it does not make much of a difference.(actually on some applications it is preferable a bit slower) it cuts, grinds,brushes through and on materials without mercy with pressure applied and no signs of slacking down....- for about 15 to 20 min. then the battery gives up on you...( hey- its a cordless tool) i think for 90% of all the work you perform with angle grinders it will give you the freedom not to to have look for a plug, find an extension cord, get tangled up in all your mess and find out at the end that you still short one foot to reach your workpiece. (sounds familiar) it will help to keep your blood pressure down. but if your work requires an extended usage ... stretch out the cord. unless you are like me(hardheaded/stubborn) and insist on to use this tool going all the way through (same for the hammer drill, saw) a third battery pack is needed (talking about the 20V-3.0amp) since it takes longer to charge the battery than what you have on running time available.[update 1.13.15 with the 5amp battery's it's not even a issue worth mentioning it] my short wishlist of improvements is a BELT CLIP (i'm missing it on my hammer drill since it is not supplied with it and i don't want to spend 10 bucks extra :( ) and variable speed or at least three settings. this would open this tool for a far wider range of applications. 11.24.14 i've been using this thing now for over a year on regular base. like every few days. i only can add that in regards to the quality of tools dewalt tops the list. still going strong this thing.

This DeWalt 20V Grinder is a great value for DIY or hobbyist use. It has a comfortable grip and works great on most tasks. Its can cut through sheet metal and rebar fairly easily (with a quality cut-off wheel). Also, with the grinder disc, makes it easy to clean off burrs and other jagged edges. It is fairly compact, not as small as corded grinder, but this is offset by the portability.

Admittingly, I never owned a grinder before purchasing the DCG412. I had used a small air powered die grinder in the past, as well a larger disc sander. But I never really had a need for a grinder. That is, not until I got this one. As with most of the new Dewalt 20V Max tools I have purchased, I first set out to find out what accessories were available and then acquired them. I had to go through a learning curve to understand why I couldn't use 5/8" grinding wheels on a grinder with a 5/8" shaft (7/8" only), but once I figured that out, I was in acquisition mode. I have an assortment of metal & concrete cutting/grinding wheels, flap discs/wheels, carbide blades, and wire wheels. I found the enclosed top wheel cover and spare flanges/nuts at eReplacementParts. I even found a thin sided wrench on Amazon to tighten the inner nut on the fixed hub wheels. Unfortunately, the wrench wasn't quite thin enough, so I used the DCG412 to take a 1/6" off of each face. Now that's ironic. Everything fits nicely in a 15" Dewalt bag. No use having a powerful tool and then not having the proper $4.00 accessory when you really need it. I have only used this grinder 3 or 4 times for real projects so far, as well as dozen test grinds and cuts on various materials. The results have been better than expected. Still kicking myself for not owning one of these years ago. A multitude of projects that could have been simplified with a grinder and the proper accessory. Be sure to have a spare battery or two handy, as the DCG412 uses a good amount of juice to do what it does. Now I understand why Dewalt does not make any cordless sanders, that often need to run for really long periods of time. Being cord free though, makes the DCG412 a joy to use. Nothing to get tangled while you're changing guards or attachments. And nothing to trip over, allowing you to focus on your work. That's rather important when working with grinder, a potentially dangerous tool in inattentive hands. Safety first.

EXCELENTE HERRAMIENTA, DE BATALLA . PARA TRABAJOS Y AMBINENTES DUROS .

So I’ve been debating on what to do for a long time now as far as cordless angle grinders go 3 years ago my wife and I bought a new house and we moved the barn we got for my workshop isn’t hooked up to power so it’s all solar power lights and battery operated everything and if I need to weld or use my compressor run the extension cord so I have been systematically replacing all my power tools to cordless however prior to the decision to move I had my toolbox broken into and lost thousands of dollars worth of tools specifically my 1/2” chuck 20v cordless drill my 1/4” hex drive impact driver and the matching 1/2” drive impact wrench with 3 batteries and one charger so after the move I was faced with the need for a new cordless drill and driver as after the theft where we were living I had been using spares that belonged to my father however it wasn’t a possibility after the move and being that we had just purchased a new home it was just coming to the end of Covid and prices were silly and the most economical way to go is to buy a starter set that has the drill and impact driver 2 batteries and one charger normally in a canvas carry bag well with my options locally and sales at the time I decided to go with the Bosch set that gave me an 18v hammer drill with 1/2” chuck and the 18V Bosch freak impact that’s a 1/4” impact driver built into a 1/2”square drive impact wrench anvil 2 batteries and a charger naturally the crossover Bosch freak without the loss of torque that comes with using the hex drive to square drive adapters or the extra head length and not having to go without a tool I used so much but couldn’t afford so last year when the time came to get an angle grinder I came across the Bosch 4.5” cordless and found one in the deals n steals section regular 199-250$ down to 115$ without taking the time to read too much or think of power consumption beyond dimple battery compatibility I ordered it that’s when I realized that for those type of cordless tools you really want a minimum of 4amp hour batteries higher is better all I have is the two I got with the kit that are both 2AH but what’s worse is it turns out to be their X-lock system and you can use c-lock accessories on traditional grinders but you can’t use standard attachments with an X-lock grinder unless you add the adapters to give it a traditional screw on lock but mandrel generally either 5/8-11 or M14 thread so that’s what I did I got that and I’ve got a surplus of DeWalt style batteries all 5-6.5 amp hours so I got an adapter that allows me to use dewalt 20v max style batteries in my Bosch 18v core tool the issue arises in the fact that the adapters for the accessories push the cut off wheels or wire cups out by about one full inch and there is no way to lock the mandrel so in order to get the lock nut in place you need to put it in a vice or something else that can lock up the adapter wbile tightening or loosening the accessories add the extra 1.5-2” added to the rear of the grinder for the use with the dewalt type batteries and the extra weight causing the batteries or the adapter to slip slightly out of place and cutting off power to the tool and you end up with an excessively Heavt and long angle grinder with a tendency to cut out when working overhead at odd angles and being restrictive on where it fits as I learned while trying to use it while patching up a hole in the muffler of my wife’s car which I was doing on the ground with a floor jack having lifted the car enough to allow me to reach now I had been planning to get the Ingersoll Rand IQV20 angle grinder in the near future because when I upgraded to a stand alone impact wrench I got a 3/8” drive Ingersoll k22 kit that came with a 2.5 amp and 5.6 amp batteries so having the charger and one high amp battery makes the IR bare tools almost affordable still a bit out of my price range atm and I have used the Dewalt DCG412B many times recently and really liked the way it has a momentary switch instead of a toggle switch like my Bosch had much like budget corded angle grinders well I had thought to get a couple of wire wheels and cups for the x-lock and then a battery or two in the 4-8 amp hour rand specifically aftermarket options as the majority of my power tools are now based in either 12volt Milwaukee M-12 or dewalt 20V max and the dramatic majority of my batteries for both are aftermarket options all fine and dandy except I’ve had mostly good experiences with aftermarket batteries but have had negative experiences as well and I was looking at 75-100$ for two but the jarring part was the prices for single X-Lock compatible attachments like 14$ for a single grinding disc my thought was get grinding wheels flapper discs and a 4 pack of wire wheels/wire cups as those are the ones that cause the most jerkiness and excess vibration while adding extreme weight and extra bulk to the front of the tool and causing concerns for premature bearing failure I never did find the wire wheels and cups the reason why is I have the right angle die grinder from Milwaukee and it’s a love hate relationship with the tool that is worth it’s weight in gold but I got it a week before the gen 2 was announced and I never would’ve got it had I known that the gen 2 was coming however it works amazing with 2” roloc and Velcro sandpaper attachments burrs and 2” grinding stones I haven’t had the opportunity to get any 2” cutoff wheels yet but I have no doubt it’ll take them without hesitation plus I have the 1/8” collet adapter for dremel style accessories so really the major need for the candle grinder now is for wire wheel type attachments that are heavy enough to cause issues with stalling the die grinder and for grinding discs to eat through large amounts of material extremely fast! difference between tgat and what I use on the die grinder is the die grinder I have 2” flanged grinding stones like what you find in the bench grinder where as a grinding disc is basically a cutoff wheel that’s 3-5X thicker and has the abrasive texture on the faces instead of on the edges one does a cleaner job and takes much longer to get the job done the other is a little more crude and munches through steel like a termite through your new house and that’s when this came across my radar already liking the tool and being set up for it however Not looking to spend 150$ and even on sale it wasn’t the IR I really wanted and the last time I didn’t get exactly what I wanted and settled for something that was at a price point that I was more comfortable with spending at the time and that seemed to make sense the difference being that I have first hand experience with the dewalt where I didn’t have any with the Bosch I also spent a long time making sure it was exactly what I was looking for and the same thing as I have first hand experience with and after 2 weeks of going back and forth in one in the deals n steals section for a good discount in open box Type condition and knowing that the last time I got a power tool that way it was impossible to tell the difference between it and one that was 100% brand new no marks or signs of use and worked 100% identical to brand new and the thought was if I was already looking at spending 75-125$ on a couple aftermarket high amp Bosch batteries and a couple of X-Lock grinder attachments why not simply get the dewalt I’m familiar with knowing that the whole 2 hours max of use on my. Bosch and it being in near new condition plus the 2 adapters for traditional accessories and the quick release flip up D ring lock nuts it’s easily worth the same price as the Dewalt was so my justification was that I’d sell it to cover the cost of the Dewalt that way I wasn’t any further behind but further ahead and in the next year or two go ahead with the IR angle grinder and that way I can have two different grinders set up for different tasks like the wire wheel on one and a cutoff disc on the other type setup however I have found that I don’t use my Bosch tools at all anymore with the exception of the hammer drill inside my house mostly used with a 16” paint mixer to mix 5 gallon buckets of water and salt mix for use with my saltwater aquarium as I’ve kept the drill in the house and the freak in my workshop for the entire 3 years I’ve owned them allowing me one 2 amp hour battery and most often I find that I’m using it for short periods of time allowing me to get a single high amp battery and still have one standard duty 2amp battery at my disposal which will also charge exceptionally fast making it a reasonable solution to have a second tool that’s set up for ease of workflow and aside from the cost of attachments and local availability I know they’ve been out long enough and with. Both Mikita and Bosch having adopted the system it’s unlikely that they’ll stop producing accessories for the tools even if they’re only available online etc if I’m not dependent on the angle grinder with xlock as my only option as my main tool then I can systematically collect the attachments I think I need most and stockpile the odd extra grinding wheels or wire wheels or wire cups Etc. That way I have extreme modularity and speed of accessory changes and eventually potentially being moved permanently to my travelling toolkit for mobile repairs if I were to keep the Bosch that is and still go on to get the IR of my dreams that said I’m not finding myself obsessively checking to see if the IR is onsale like I had been doing prior to acquiring my Dewalt I’m more than content with the decision and although I wish there was a latch to lock the trigger in the on position without having to pull the button features like the fact that you can remove thr 4 case screws and to turn the mandrel/head assembly 90% so that the tool side is essentially upside down to the handle so when holding it as normal in the modified head position the grinding disk is facing the ceiling instead of facing the ground as normal in situations like I’ve been recently where I’m welding a patch on the muffler if my wife’s car while still on the car and only have a full sized 3 ton floor jack to lift the one corner of the car to gain just enough clearance to reach with my grinder to clean off slag and and excess carbon from the exhaust leak that’s getting smaller but I’ve yet to have the opportunity to finish the job as she keeps needing the car midway through the job and 50% of the time I’ve found myself removing the guard and holding the drinker upside down while cleaning the top part of the muffler turns out these Dewalt angle grinders use brushed motors and sure after using the Bosch and the Dewalt side by side there is a noticeable difference in speed even though I’m using wire cups with the clock to threaded mandrel adapter and a 2 amp hour battery vs the Dewalt with a drinking disc with a 5Ah battery one would think that the brushed Dewalt would still have more power /speed than the brushless Bosch in that case however it’s not oddly enough either way I have absolutely no regrets whatsoever as far as purchasing this Dewalt DCG412B well actually that’s a lie I regret having not bought it sooner than now all in all it does the thing has extremely good power and well balanced and it simply feels right in the hands and most importantly it does the thing sure it’s an older design and about as far from the XR line as you can get while still being in the 20V max lithium battery platform yet it still keeps up with a current Bosch which isn’t the top of the line or setting the industry standard but it’s also no slouch either just a really good representation of what a professional level cordless angle grinder and this Dewalt that was released in what 2016? And basically been obsolete by what 2018-2019 yet it’s still chugging along being sold brand new in stores everywhere that should tell you something beyond how versatile and how much value it’s got to offer and most of all it just simply does the thing and what better deal can you get than that!!

Très satisfait, utilisé une grosse batterie parceque ça consomme du jus avec une brosse à métal , parfait pour un bricoleur occasionnel

exelente , 😁👍

Buen producto.
