Milwaukee M18 FUEL ONE-KEY 18-Volt Lithium-Ion Brushless Cordless 1-3/4 in. SDS-MAX Rotary Hammer (Tool-Only)

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.

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!

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 POWERSTATEâ„¢ 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 AUTOSTOPâ„¢ 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).

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.

AWESOME tool. Excellent, long lasting power for a cordless hammer drill. Built in clutch which stops drill at 1/4 turn when bit locks. Great feature! Have nearly broken my wrist numerous times with my corded hammer drill. As a member of Milwaukee’s One Key system the drill can be linked via blue tooth to your phone so its location can be tracked, it can be remotely locked, the tools performance can be adjusted, and you can get reports on tools usage and performance. Used drill to put a 4″ hole thru a very old house for a dryer vent. Wall was 15″ thick, 2 courses of brick, 6 ” of concrete and stone, then 2″ of cement and plaster. OMG. Tool cut 4′ hole thru all of that in less than an hour. Still had battery power left!!

If you do any masonry or concrete foundation drilling, this is the rotary hammer drill to have. Keep in mind it is a bare tool only, so you must own and have your own M18 battery system to use out of the box. In use, the chuck is easy to use and holds most of the large size masonry bits with easy. The rotary action works well with minimal fatigue felt by the user when in operation. Sturdy, strong and of high quality and has taken a beating on the job site with ease.

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!

Pleasantly surprised at the performance of this rotary hammer. Worked pretty well at partially demolishing a small concrete pad – even with a lower capacity M18 battery (XC 3.0) instead of a larger 5.0 or 9.0 battery. I like that it allows you to easily change the chisel orientation so that you’re always using it at the most comfortable angle. The tool has sufficient shock absorption which makes it rather comfortable to use – at least once you get used to it’s somewhat hefty weight!Apart from some test holes, I have yet to use it as a hammer drill for extended periods. The few holes I did drill with it (3/4″ only) were made without a single hiccup.

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.]
