   This roto hammer is a beast! We’ve all been skeptical when it comes to high energy draw tools going cordless, but this tool doesn’t disappoint. A few years ago, the 1-1/8 Milwaukee SDS plus came out and we couldn’t believe how fast and powerful it was. I put my BullDog in the shed for awhile and finally gave it to a friend after not using it because Milwaukee’s M18 was just more powerful and effective. Now (amazingly) Milwaukee has come out with an SDS MAX that overpowers corded models at the same price. We drilled 3/4 holes in old strong concrete faster than a corded blue and grey roto hammer. I wanted to be nice to the other brand so I’m just showing images of this tool beating my smaller but still potent Milwaukee cordless hammer drills. If you’re doing big work probably have 3 or 4 High output 12.0 batteries and a rapid charger. But most serious contractors will have those anyway. We have nine of them on hand. You absolutely won’t believe how hard this tool hits. Slow RPM and massive impact on this tool helps your expensive SDS MAX bits last longer too. Highly recommend for pros. For homeowners and handymen, there is a great Milwaukee sds plus M18 available that’s cheaper and still very strong. For pros, this tool is a must.

   This is a pricey purchase, but it pays back big time in efficiency and convenience. We never had an effective portable hammer drill and depended on AC or compressed air to do our concrete demolition. It takes a huge amount of time, effort, and budget to provision feeds for a remote job site or obscure location. Well, the product claim on this model is true – it has all the power of a corded 15 amp hammer and the 12 amp hour batteries offer incredible duration. That Milwaukee did this without adding appreciable weight to the tool is impressive. It’s nicely balanced in horizontal and vertical use with intuitive, well placed controls. The side handle adjusts smoothly and is well located on the nose. Our guys love the anti vibration features on both the side and the rear handles – really eases extended chiseling fatigue. We don’t install many anchors, but the drill and hammer drill modes seem fine – gearing is a little low, but probably needed to achieve the needed torque from a battery tool. The rotation clutch system works like a charm – immediate and consistent release. The bit chuck works perfectly and is easy to clean. I see that there are bit vacuum attachments available for OSHA complianceThe batteries charge quickly and the charge gauge is handy. We’re not using the Redlink location feature, but I imagine it’s helpful for tool control with large crew operations. All in all, a huge time saver and a great investment.

   This M18 FUEL ONE-KEY 18-VOLT LITHIUM-ION BRUSHLESS CORDLESS 1-3/4 IN. SDS-MAX ROTARY HAMMER WITH ONE 12.0 AH BATTERY is incredible! The power and weight are perfect for the job I used it for, which was breaking up my patio to replace it since it was cracked. I will also be buying a Milwaukee hammer drill soon since the battery on this will work for that, too. The battery has higher capacity than others so it will last a long time.

   This is a big Tool for hammering it out. First off i like the size of the tool an i feels great in my hands as it hammers even the hardest of surfaces. Sometimes after a long day of hammering i like to just sit there and look at the tool and am amazed at the job its done. It certainly has changed the way i get the job done!

   This tool has great power, wow. I have many other Milwaukee tools but this one my favorite. The cordless rotary hammer has ultimate power, control, enhanced safety, and productivity. The M18 REDLITHIUM™ High Output HD12.0 battery delivers unmatched run-time in all applications and this one comes with two, which is really a plus considering how expensive the batteries alone are. I am so happy to own this wonderful cordless hammer.

   This is a review of Milwaukee’s #2718-21HD SDS-Max Rotary hammer drill kit.It comes complete with a rugged hard case, a single 12.0 A-hr battery, ans a much needed rapid charger.The motor is brushless.It is made in China.This is a massive hand tool, weighing in at ~ 25 lbs with bit attached. I have several tools with the One-Key feature … and I don’t use it.Being cordless, it’s a joy to use over my previous corded 15A SDS drill.I’ve used the drill primarily in three ways: while held horizontally, core drilling through 8-12″ foundation block/brick walls; both vertically and horizontally, setting masonry anchors up to 3/4″ D x 4″L; and holding vertically, demo’ing small 4″ thick concrete pads.Needless to say, the most difficult challenge comes with using this massive tool horizontally [fortunately for me, the pilot bit on the bore saws helps]; the 45-deg ‘auto stop’ feature works so the fear of wrist strain and possibly broken arm bones is almost gone.I find the vibration with the tool to be somewhat less than taxing on the body.The battery life? I can easily knock out four holes on a single charge; breaking up a 4″ concrete pad … used 7 full charges for 170 sq ft … I think that comes to 1,200 lbs per charge … more than the “1/2 ton per charge” claimed in the merchandising material! [This was nearly an ‘all day affair’ and what I would consider a torture test. It passed with flying colors.]

   380 revolutions and 2,900 beats per minute generating 8.1 ft-lbs impact energy make this rotary hammer a heavy hitter. Using big HD 12.0, 18 volt, batteries provides a strong and relatively long lasting power source. The two batteries charge up quickly as well, just 96 minutes for a full first charge. The small LED light lights up the work area adequately.With the ability to drive a 1-3/4 inch diameter bit into reinforced concrete or chisel away a half ton of material on just one charge this tool is very powerful and has massive torque but the built in safety of the AUTOSTOP E-Clutch stops the machine dead if it twists 45 degrees suddenly, no doubt saving many a sprained wrist, or worse. The built in shock absorption is clever too and it really is most efficient and productive to find the sweet-spot between trying too hard and not hard enough.Ongoing development of the ONE-KEY app continues to add features and the ability to remotely locate and disable / enable ONE-KEY equipped products is well worthwhile. The kit even includes lubricant to apply to the bit shank. Adding a generous compartment for bit storage in the case is a thoughtful touch.

   The M18 FUEL One-Key 18-Volt Lithium-Ion Brushless Cordless 1-3/4 IN. SDS-MAX Rotary Hammer with One 12.0 AH Battery. I actually used this SDS Hammer for removing brick from an interior wall in our kitchen with a wide chisel bit. The Milwaukee SDS Hammer done it with ease ! This Milwaukee Hammer is a very powerful Hammer ! This hammer uses the SDS MAX blits, and this kit comes with everything you’ will need except bits. It has features like a vibration damper built into the handle, and the ONE-KEY as well ! I have a project with an asphalt driveway, and some concrete to do with this Milwaukee, and I will update on here when I do that. No doubt in my mind, this Milwaukee can handle it ! Thank you Milwaukee for making such a great Cordless SDS Hammer ! And Thank you Home Depot for handling the Milwaukee Tools !

   I bought this as I was so tired of using a 1/2” hammer drill. My first use was to drill to place rebar into a slab preparation. Drilled 5/8” like it was butter. I then used the hammer feature to break some surface boulders popping in my yard. It made quick action and saved me from digging with the backhoe and then fixing the lawn. I also used this to drive rebar to stabilize concrete forms. I also drove an 8’ grounding rod in hard pan fairly easily.

    I’ve used this to break up a concrete footer left in the driveway from an old porch, cut out a bad section of blacktop in the driveway, break up a dirt pile full of roots, remove mortar from field stones to rebuild a wall, and bust up a concrete fence footer to repair a rotted fence post. In all cases this tool breaks things up pretty quickly. The tool weighs about 25 lbs when outfitted with battery and bit, but it’s very manageable given the shock absorption, adjustable handle, and ability to rotate the chisel before using hammering mode. The kit includes the brushless, 1 3/4” SDS-Max rotary hammer (model 2718-20), two M18 REDLITHIUM, high output, HD12.0 amp hour batteries, Rapid Charger (40% faster), a tube of grease for the bits, and what is a giant red suitcase. The only thing missing, which is surprising, is a depth gauge. You’ll also need bits and chisels, but that will depend on how you plan to use the tool. Given my intention to chisel concrete, my first bit purchases were a 3”x12” scaling chisel and a bull point chisel.Per the literature, this tool can “chip 1/2 ton of material on one charge.” In my case, each new, fully charged, HD12.0 Ah battery provided approximately 20 minutes of run time when chiseling concrete and blacktop. Perhaps there’s a technically difference between “chipping” and “chiseling,” but I definitely didn’t remove 1/2 ton of material on one charge. Also, I noticed that as the batteries got to the last bar and started blinking, the tool’s power started to drop off a little. Luckily, the batteries run cool so they can immediately be placed in the charger. With the Rapid Charger, each of my HD12.0 Ah batteries charged in roughly 1 hour and 40 minutes (from blinking). You can’t beat the convenience of a cordless tool, but if I had to run this thing all day, I’d consider investing in more batteries and chargers. The One-Key features aren’t important to me, but as a curious individual I downloaded the app and connected the tool to check it out. I can understand how the app would be useful in professional applications. Milwaukee has delivered another well-engineered tool that is comfortable and as powerful as a 15 Amp corded rotary hammer. I really enjoy using it!

    What an awesome tool this M18 FUEL ONE-KEY 18-VOLT LITHIUM-ION BRUSHLESS CORDLESS 1-3/4 IN. SDS-MAX ROTARY HAMMER WITH ONE 12.0 AH BATTERY is! I have been a builder remodeler for 49 years, so I have a little experience in the use of tools, in fact I have a reputation of having every tool known to man! But one tool I haven’t owned until now is a big rotary hammer, as I don’t usually use one all the time. So I’ve typically rented a corded one. But it just happened that I needed to drill 120 holes in an existing foundation to retrofit anchor bolts, and I also needed to drive some ground rods. So when I got this, it was the perfect tool for the job! The only thing it lacked was a second 12.0 AH battery, but I also picked up one of those, and then I was ready to drill & drive! And boy did it do the job! No cords, power to spare, I’m not looking back! This is one awesome tool! I absolutely recommend this tool!

    This beast will definitely get the job done no matter what the job is. I love this thing, i got it primarily to demo a bathroom and it did not disappoint. It chewed through the tiles like they were nothing and easily handled the shower surround which was tile and concrete backer. i got through the majority of the work on a 5aH battery but could see how a 12aH could really allow you to work all day with this thing. I even used it on some solid core cinder blocks with no issues turning them into dust. The hammer is well balanced and even though it weighs in at nearly 20lbs does not seem that way when you start to use it because of the way it was designed by Milwaukee the tool does all the work for you. I also like the safety features they have added to prevent the drill from spinning more than 45 degrees in your hands if jammed or stuck. The thing is obviously made of quality materials appears super sturdy and able to take whatever beating you throw its way. I do agree with Milwaukee that this thing as the same power as its corded counterparts. The only con against this thing and it is really not a con is the cost of drill bits associated with the 1 3/4 in bit size. The chisels are pretty cheap but those drill bits can run in the $200 range so watch out for that. But other than that I would not let anything scare you off from picking this Rotary Hammer up, it will definitely make your jobs easier. The other great part about this tool is that it is part of the one key line so you can protect your invest with the app. Definitely would recommend this rotary hammer

    I am a professional contractor and I was in the market for a heavy duty rotary hammer drill. I picked up the Milwaukee 1-3/4 SDS Max M18 fuel 18 volt, one key lithium-Ion brushless, cordless rotary hammer drill. I never owned a cordless rotary hammer drill before. Let me tell you I was a little skeptical, but, I was blown away with the performance of this Milwaukee 1-3/4 in. Rotary hammer drill. The hammer drill came in a heavy thick box and the contents that were in the box was the drill and side handle, owner’s manual, One key quick start guide and a tube of grease for the bits when inserting into the drill. The drill itself weighs 19.7 lb and is 19.1 in. long and 4 1/2 in.wide and 13 in. in height. This drill also comes with an outstanding 5 year warranty.This Milwaukee rotary hammer comes with a ton of options. For example: it comes with a LED light that illuminates the area for drilling. On the top of the drill there is a selector knob for hammering only / hammering with rotation / and chisel adjustment 3 different positions. The trigger handle and side handle are called AVS and are shock-absorbing and that will save my hands and arms from becoming numb like on my old hammer drill did to me. Also on the handle it has a chisel lock switch for safety. Milwaukee has also added an auto stop E-clutch that is a dream come true for me. When drilling a hole and the bit binds up instead of the drill spinning out of control and breaking your wrist or fingers it will come to a complete stop immediately with this feature. After it rotates 45 degrees which equals a 1/4 turn. On the inside of the handle there are two indicator lights 1 for the one key and the other one is for the service Tool light. The Milwaukee hammer drill is heavy duty and Powerful. The impact energy is 8.1 ft-lb at 380 RPMs and hits at 2,900 blows per minute. That is impressive. Milwaukee claims this hammer drill is powerful as a 15 amp corded hammer drill and I can contest’s to that it’s pretty strong.I am happy that I won’t have to carry around a heavy extension cord to run this hammer drill anymore. This one key track and manage system helps you control speed of the hammer drill and track your tool if it gets stolen. This is a perfect option to prevent theft. I will never miss changing brushes anymore because this is a brushless motor.If you buy this Milwaukee hammer drill make sure you get a case with it to carry the hammer drill and your batteries and accessories. If you need to drill through concrete or brick or break up concrete or brick this is the rotary hammer drill for the job. Milwaukee stepped the game up with this 1-3/4 in. SDS Max rotary hammer drill.This rotary hammer drill may look intimidating due to the size, but, it is user-friendly and it gets the job done with ease. Just pull the bit release collar back and insert your chisel bit or drill bit and you’re ready to go.When I show this Milwaukee rotary hammer drill to my contractor Buddies I know they will fall in love with it just like I have. Overall this is the nicest hammer drill I have seen on the market, lots of thought out features which makes this hammer drill stand out over other brands. I definitely give this Milwaukee 1-3/4 in. SDS Max rotary hammer drill 5 Stars there is nothing that you would not like about this drill. I do give my recommendations on this drill

    Drilled 5/8” holes like a hot knife thru butter. The hammer function was great for driving stakes and grounding rods. Well worth it.

    The milwaukee sds max cordless drill is great. The drill is of good size so it does have some weight to it, but it is very well balanced and easy to use. The run time on it is a pretty decent run time. It’s perfect for doing a few hole and small concrete demo jobs. It definitely wont replace a corded version, but does have it’s place in your tool arsenal. The auto stop rotation feature it has on it works great. As soon as it sense’s a bind and starts to do that naste kick it cut’s it off before it hurts you or you even feel it.

    The past few years now Milwaukee has really been implementing a lot of new features and technology that make tooks better and safer to use. This 1-3/4 SDS-Max Rotary Hammer is no exception. This thing is a beast of a drill and cordless too thanks to the M18 12.0 batteries. It will work with smaller capacity batteries but you won’t get as much run time, and possibly performance out of it. With the 12.0 battery it goes head to head with the comparable corded version.If you’re doing demo or drilling through concrete where services haven’t been installed yet or if you just like working without cords for safety and convenience, this rotary hammer can tackle a lot of tough jobs previously only a corded drill could. All the buttons, switches and controls are easy to use with gloved hands.Some quick max capacity recommendations… twist bits 1-3/4″, core bits 6″ and tunnel bits 2-1/2″. This is a heavy drill meant for heavy jobs like demolotion and drilling big holes through concrete. The back part of the drill with the handle has dampening bellows as does the side handle which helps minimize the vibration that gets back to you while operating. It weighs almost 20lbs without the battery and has a lot of power. If the bit gets stuck while drilling the Autostop clutch will stop the drill and only let it turn 45 degrees to minimize damage to you or anything nearby. There hasn’t been a condition to test it out and for my own safety I’m not going to set up a situation to test it intentionally but the videos are convincing and other Milwaukee M18 drills that have similar safety features have worked perfectly for me in the past when the bit bound up. This is a very important feature to have especially if you’re working in tight spaces or on a ladder. There’s a lot of safety information in the manual which is worth reading.There’s no reverse or variable speed trigger which isn’t uncommon in an SDS-Max drill like this. If a drill bit gets stuckyou can try setting it to hammer mode only to try to get it unstuck or use other means.The ONE-KEY app is nice if you have a lot of expensive Milwaukee cordless tools to keep track of across multiple workers and jobs sites. It can help keep track of lost or stolen tools. Any time someone with the One-Key app comes within 100 feet of a One-key tools the location of that tool will be updated on Milwaukee’s servers. If multiple people use your One-Key tools, make sure they all have the apps on their smart phones so tools don’t get lost and you might have some help finding them if you can’t remember what truck or jobsite it was last used on.If a tool does get stolen and you mark it as such in the app the tool will be locked the next time it’s in range of a smartphone running one-key. Making it unusable until it’s unlocked. The app also also you to mark the tools location or who the tool was assigned to. The app is well done.This isn’t the type of drill that everyone will need but for those that do and want it cordless this is a great choice in my opinion based on the clutch and performance.

    M18 Fuel one key 18v Lithium-ion Brushless Cordless 1 3/4 in SDS – Max Rotary Hammer Tool OnlyIs a great tool. Weighing in at just under 20 pounds (bare tool only) it has some weight to it but if used properly, really isn’t too heavy. Let the tool do the work. Just light pressure will give you great results. This uses only the SDS Max bits unless you have an adapter Milwaukee makes to except SDS Plus bits. This has the power of an 15 amp corded hammer and I feel it really does. I have used many rotary hammers in the past and love this one. Will do small and large jobs. It has a trigger lock so you don’t have to keep it depressed while using it. Just pull trigger again to release it. I only have the 9.0 batteries to test with. I imagine the 12.0 is the Perfect match with this tool. The 9.0 works just fine in it. Will use and M 18 battery but with much shorter run times. The one key adds the ability to know where your tool is at any given time. If turn the dial on top you have a setting to adjust the bit so you can hold the hammer in a more comfortable side to use it. With 8.1 ft-lbs of energy and 380 RPM and 2,900 BPM this will get the job done nicely. I highly recommend this for your tool arsenal.
