   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.]

   I can’t believe how hard this tool hits. We did some real work with it. We already retired our corded sds plus after Milwaukee came out with cordless Fuel 1-1/8. Now amazingly this SDS MAX makes a cord unnecessary for big work. If you’re a real contractor, you probably have 12.0 Milwaukee batteries on hand anyway. You’ll want two or three if you’re working all day with this roto hammer. You won’t be disappointed.

   Milwaukee makes another excellent product! This drill is not compatible with the SDS Plus bits and chisels. You must use SDS Max bits and chisels , which are sold separately. The tool comes with one battery and one charger. Extra batteries and chargers are available through Milwaukee for purchase. The tool has three selections to choose from, simply turn the sector knob to hammering with rotation, hammer only or chisel. The drill also has a chisel lock feature, which is nice to have. This tool comes with One-Key, which tracks, locks and renders it unusable at your choosing. This application can be downloaded onto all Apple and Android devices. This cordless rotary hammer has a 5yr limited warranty and comes with its own carrying case. However, I would like to see Milwaukee include a starter bit and chisel set as well as a re-engendered battery charger, which has zero humming. I spoke with the parts and an engineer from Milwaukee whom said it’s not a safety concern. The humming gradually goes away as the battery charges.

   POWERFUL; VERSATILE; HEAVY; LABOR-SAVING — The Milwaukee M18 FUEL ONE-KEY 18-Volt Lithium-Ion Brushless Cordless 1-3/4 in. SDS-MAX Rotary Hammer with Two 12.0 Ah Batteries is an incredible, portable tool which has many applications. It can drill, chip, trench, make core holes, and much more. Tile and concrete contractors should be interested in the tool for its ability to save labor costs. Serious DIYers could use it for multiple applications to justify its cost. For me, it allowed me to remove my old ceramic tile floor in less than half the time that it took a contractor using a hammer and chisel to remove the tile in a similarly-sized bathroom. The best feature for me was the vibration damper. Another excellent safety feature is the auto stop clutch to keep the tool from rotating more than 45degrees if it gets stuck. This tool is huge and heavy. It weights 23 pounds including the battery which weighs 3.2 pounds. The weight may be the biggest drawback for people who would not be using it frequently. The well-designed trigger handle is comfortable. The side handle adjusts easily. That handle and the overall balance make the tool easy to use. The three modes are clearly marked and explained in the instructions. The chisel lock mechanism is not clear in the instructions. To insert a bit, you need to pull back on the spring loaded collar, then release it to lock the bit. The temporary setting is for adjusting the angle of the chisel. This step requires caution since you need to pull the trigger with the battery engaged. The tool case is large and has room for many accessories. The kit includes a tube of lubricant but the instructions for using it are missing. The drill has ONE-KEY with all of the associated advantages. Two current drawbacks are the lack of accessories and their cost. I needed a tile chisel bit for removing the ceramic tile in my bathroom. My SDS Plus tile bit is not compatible. I would have needed to buy an adapter at a cost greater than a new bit. Milwaukee does not make a tile chisel bit for the SDS Max but advised me that another vendor did. That vendor’s bit is HD store exclusive which means that it can only be obtained in a store. My store did not have it and had not seen one in months. I could not order one online. Fortunately an HD store manager figured out a way to obtain the bit for me. Bits can cost more than $100 each. One then needs to have specific, large tasks in mind. For those tasks with available bits, this tool will increase one’s productivity and make the tool a wise investment.

   The Milwaukee 1-3/4 inch SDS-MAX Rotary Hammer performs admirably. It can support solid drill bits up to 1-3/4 inch in diameter, core bits up to 6 inches in diameter and tunnel bits up to 2-1/2 inch in diameter. The tool can hammer only or hammer and drill. It also supports a setting to allow chisels to be orientated to best fit your work surface. One nice feature of this tool is the safety clutch which will stop the drill within 45 degrees of rotation if the bit gets stuck while drilling. It produces 8.1 foot pounds of force and 2900 beats per minute. This model also supports One-Key and the tool can be put into security lockout preventing its use until the owner removes the lockout. This particular configuration (2718-20) is a bare tool so there is no case, batteries or charger included. For your money you get the tool, a tube of grease and a manual. You save money on this configuration if you already have numerous Milwaukee batteries and chargers.I really liked the anti-vibration system on the trigger and side handles. While I used the tool to break up a concrete post footing, I did not experience any fatigue from vibration. The tool is heavy (nearly 20 pounds) but when drilling or hammering on the ground, the tool weight helps apply pressure to the bit. If I was working on a vertical surface I’m sure I would become fatigued by the weight but the competitor products have similar weight.In my initial test on a 24 inch deep concrete post footing, I used both a bull point and a flat chisel to break up the concrete in hammer only mode. The rotary hammer broke up the concrete quickly and without a lot of effort. I only had M18 5.0 Ah batteries on hand. The tool worked fine with them but I did have one over heat during use. I definitely recommend a high output 12.0 Ah battery for use with this tool since it runs 50% cooler than other M18 batteries.The tool does have a trigger lock for long duration chiseling. What it does not have is a reverse mode so if you get a drill bit stuck, you cannot back it out with reverse and will need to find another way to break it loose. This product has a five year warranty which beats the major competitors. There are multiple types of SDS bits: SDS, SDS-Plus, SDS-MAX and Spline. SDS and SDS-Plus are interchangeable. SDS-MAX is a thicker shank for heavy duty applications. SDS-Max was designed to replace Spline shanks. This particular tool uses only SDS-MAX bits but Milwaukee sells an adapter that converts SDS-MAX to SDS-Plus.

   Has not disappointed me yet. 12 Amp batterys provide enough juice for most residential hvac projects. Just as heavy as my hilti without the extension cord stress.

   First Milwaukee heavy duty product I have had the pleasure of owning. I must say this tool is beyond amazing. Being a bit concerned over the battery power became a faded thought as it is as advertised— ready to do the job. For my purposes it is a bit overkill as this would be ideal for full time concrete work without any down time should you get a second battery. if you are a really aggressive worker you could probably get by without it. Been remodeling my house and will be using it to drill holes for new railing and roof supports on two porches along with driveways etc. This is in a different league as a regular hammer drill I can assure you. The Autostop E-Clutch is a very nice safety component. Looking forward to a longtime usage, reliable and quality power tool by one of the best manufactures around.

   Milwaukee Rotary Hammer model # 2718-22HD review by a home owner / DIY’er.I’m a semi-retired I.T. technician so I try to leave data cabling jobs to younger techs, but sometimes I get roped in. Most of the time I don’t have to run cable through masonry; sometimes, however, I’ve run into situations that call for ‘more power’ – and this new Milwaukee rotary hammer supplies ‘more power’ by the bucketful. Vibration is present, but minimal. Noise is high-pitched; you’ll want to wear hearing and eye protection. The trick is to let the drill do the work – apply just enough pressure to guide the bit. Of course, the 2718 is a beast – you can check out the specs on the Home Depot web page. (See attached photo of the case – I’ve included a yardstick to give some idea of proportion).The “lock out” for the trigger is on the back (see photo); there is a light that comes on to light up the work. A hard-shell case is included with the kit. Fit and finish is excellent.Being a DIY’er I don’t expect that I’ll wear down the 12 a/h battery on any given day, but the kit comes with a spare battery as well and a second battery is always welcome. Of course the M18 batteries are interchangeable with any other M18 tools.Every time I plant a new rose bush or shrub I have to dig out something left by the subdivision builder – cement bricks, poured concrete leftovers, you name it. I found the top half of a concrete bird feeder buried about 7” down! Also, we’re sitting on hard clay soil which doesn’t make digging easy once you get past the topsoil.The Milwaukee will allow me to cut the concrete, bricks, etc. into chunks that are easily hauled away in bags or bins. (See attached photo of SDS-Max chisel bit; the bit isn’t included with the kit but there’s space in the case for carrying a few bits).The really good news is that spade attachments are available that makes digging into hard clay much, much easier. This is where this new tool really starts to pay off for the DIY’er. This kit is obviously targeted towards skilled trades pros; however, since it also has applications around the house other than the drilling of masonry holes and it is part of the M18 tool family, the cost of the kit can be spread over a number of areas.You’ll want to check out accessories (such as the ‘spade’ bit) to see what duties this rotary hammer can perform other than drilling holes in concrete. There’s an adapter available which allows the use of SDS+ bits, which is useful.The tool offers a 5-year manufacturer’s warranty (3 years on the batteries), and a 90-day return guarantee from Home Depot. One really nice safety feature – the tool offers an auto stop which limits the tool to a 45 degree turn if the bit binds up in the work. That means that you won’t be fighting the rotation of the tool to stop the twisting motion – after a 45 degree spin it automatically shuts down.One surprising lack – there’s no “drill only” mode; you won’t be using this beast for drilling through rafters or railway ties. It would have been a handy option to have. There’s a “Hammer Only” mode, and a “Hammer/Rotate” mode. The third position on the mode switch is for changing the angle of the chisel bit.Also – Milwaukee has an online tracking database that you can key your tools (not just Milwaukee brand) into and download a nifty Excel spreadsheet showing warranty dates, serial numbers, purchase dates – just about anything you want to key in. Very handy for insurance, warranty claims, or checking purchases for income tax deductions. See the documentation that comes with the hammer for details.My bottom line on this new Milwaukee drill for DIY’ers? It would be a pricey tool to have on hand for the typical homeowner if all it did was break up concrete. But considering its other capabilities (drilling large or small holes through concrete, brick, masonry; making short work of hard clay deposits in the lawn or garden;) I think a case can be made that the tool can be cost effective. Certainly in my case, where I’m frequently called out by friends and neighbors to lend a hand in some sort of DIY chore, this thing will be a back saver.HTHRegards,Jim

   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

    This is “THE” rotary hammer to have for any tradesman to chisel, break up or drill in the toughest and hardest materials. It has the power of a 15Amp corded rotary hammer drill without the cord or the site restrictions that come when no electric outlet is available. The 2 included high output HD12.0 AH batteries included should give the user the power to chisel through a ton of concrete or heavy drilling for a couple of hours. This tool works in three modes, drill, hammer-drill and hammer only (no rotation). It is also brushless so this tool, when properly maintained and lubricated, will last as long as neededIt has a 1-3/4″ drill capacity but can handle up to a 6″ core drill. It’s size and weight makes it cut through the job required using tools that connect with the SDS-MAX and also with the Milwaukee 48-03-3025 SDS-MAX To SDS-PLUS bit adapter allows the use of SDS-PLUS bits and tools. This gives the user the ability to quickly exchange and use carbide bits from about 1/4″ up to 1 3/4″ or chisel from the smallest SDS-PLUS to the largest SDS-MAX 3″ chisel. It also has the ability to hammer in rebar or post hardware using the ground rod driver, a breeze since there is a 40 pound tool backing it up. Using a post pole adapter I was able to drive in 96″ posts to a depth of 36″ in seconds with little effort for the installation of a chain link fence.It has a safety feature which plagues many of these types of tools, that of binding up when going at full tilt and spinning out of control. Milwaukee has a safety feature that stops the drill from running away with itself and stops it within a 45* spin.This rotary hammer drill is compatible with ONE KEY™, wirelessly connecting to user’s smartphone to track and manage the tool’s performance and location.According to the manufacturer, Milwaukee, this tools features are:-Milwaukee® POWERSTATE™ Brushless Motor provides more power, more run-time, and longer life-REDLINK PLUS™ Electronic Intelligence enables advanced communication between your batteries and tools, allowing for unmatched levels of performance, protection, and productivity.-REDLITHIUM™ HIGH OUTPUT™ HD12.0 Battery Pack: Provides 50% more power and runs 50% cooler versus standard REDLITHIUM™ HD packs. Superior pack construction provides the industry’s best protection against jobsite conditions.-Generates 15A Corded Power-Max Control, Enhanced Safety-Chips 1/2 Ton of Material Per Charge-ONE KEY™-AUTOSTOP™ E-Clutch-8.1 ft-lbs Impact Energy-380 RPM-2,900 BPM-10 m/s² Vibration-2 Modes: Rotary Hammer & Hammer Only-Includes: 1-3/4″ SDS MAX Hammer, Side Handle, (2) 12.0 Batteries, Rapid Charger, Case, Grease Tube

    This is a great tool. This lost a star from me, because on the Neckbones rating system a 5 star product has all of the features and caveats of the competition with additional features of their own. This is a great tool, To me this was lacking a dust collection for the Chisel mode. The one feature I felt was lacking was the dust collection for the chisel mode. I saw another product that addresses it with their Rotatry hammers. That was missing from this lineup. The one key features for this is very limited also. When you advertise it as a one key product you expect the same customization as other one key products that was not the case, you can only identify and lock the tool and the that is it(aside from tracking it)I love finding different uses for my tools to get the most out of them. I was able to use the chisel function to break up compacted ice from the aftermath of a snowstorm. I was surprised how easily this broke up the ice. In less than a second it broke through like nothing. This was thick layers of ice too. The handle has an anti vibration spring and the best to describe it, is to think of the shocks on your car that absorbs the bouncing and movement. This worked well. I did not experience a lot of movement in my hand. The lock is easily accessible for my thumb. The case has a compartment to store bits. In the case it is quite heavy but I used my packout and similar storage units to transport it so that was not too much of an issue. I have the sds max dust attachment and it works great for drilling into concrete. I have other one key tools and the one key for this one was disappointing. Lacks features. You can only identify and lock the tool. Other one key products allow you to do much more. Performance wise this is great. Handled everything I threw at it with ease. Great for masonry and landscaping(Snow removal). Due to the Salt and water I will keep a chisel just for the snow.

    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.

    The Milwaukee M18 FUEL ONE-KEY 18-Volt Lithium-Ion Brushless Cordless 1-3/4 in. SDS-MAX Rotary Hammer with One 12.0 Ah Battery Model # 2718-21HD is a new addition to the already popular Milwaukee Brand. This Rotary Hammer generates the power of a 15A Corded Hammer. It incorporates the Milwaukee POWERSTATE™ Brushless Motor that provides more power, run-time, and longer life. This cordless rotary hammer is designed for the professional user and can be used by the advanced D.I.Y. I found this tool to be very powerful. The AUTOSTOP™ E-Clutch is a nice safety feature and I would recommend the user wear safety glasses and a face shield. Milwaukee supports their product with a 5 Year Warranty (Tool), 3 Year Warranty (Battery).

    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.

    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!

    Milwaukee M18 2718-22HD 1 3/4” capacity SDS-Max Rotary Hammer Kit is definitely a heavy duty and a professional tool. It definitely meets, head on, the comparable 15-amp corded rotary hammer by a long shot. On the jobsite, like the fact that I don’t have to drag along an electric generator to power the tool since it comes with heavy duty two capacity batteries which makes the tool totally portable. I especially appreciate the “AUTOSTOP” electromagnetic clutch that prevents the tool from over rotation when it gets bound up. This is an important personal kickback safety feature helps to order to maintain a 45-degree control of the tool, especially when hitting hard aggregate or drilling rebar which is not found on competitive brand tools. An out of control tool can easily sprain your wrist and arm, and especially cause you to fall off a ladder. The ONE KEY feature on tool allows for tool tracking, inventory, and security to shut it down and all which are great amenities to have. The battery markings are a bit misleading through the M18 representing the voltage, 18 volts, and the 12 ah (amp hour) representing the amperage capacity of the battery. I think most people think it is 12-volt. I tried to buy Milwaukee brand concrete chisel Home Depot but ended up having to buy the Bosch brand instead. It should be noted that smaller shank (SDS Plus) is for the older 1” drive and larger shank (SDS Max) is made for the newer 1 3/4″ shank tool. On the downside, the tool is very heavy and it lacks the “depth stop” feature when drilling concrete holes.

    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 !
