   it’s an overachiever. turned around an bought the smallest version of this as well and it performed better than your powered SDS. performed as good but lighter and no cords. working on a hardened concrete building – probably drilled 100 1/4” holes and the 12A battery had just lost one light level. could have gone all day.

   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.

   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!

   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!!

   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.

   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.

   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.

    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

    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.

    The M18 Fuel One-Key SDS-Max Rotary Hammer Drill is a beast. With the comparable power of a 15A corded drill this thing is strong . A bit on the heavy side but well balanced and can hold in one hand . Has a rotation clutch so if you hit something that binds the bit in will stop instead of breaking your wrist. Nice feature. This is a great tool to add to my arsenal of Milwaukee tools. I did a small job with it mounting bolts to hold a street lamp and it went through the concrete like butter. Home Depot carries all of the bits for this drill and a nice selection. 5 year warranty and everything you need to get started (except for the bits). It can also be used as a chipper to chip out concrete as well as brick. Have not been disappoint with Milwaukee tools, and this one ranks 10 on my list. It also come with one key application where you can track the tool and lock the tool and many more features, something I don’t need but its nice technology and I could see it used frequently on big job sites.

    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 really an awesome cordless rotary hammer. It literally has so many quality elements built-in, that I don’t know where to start. I was initially impressed with the side handle that practically guarantees the proper balance while in use, and is also a major safety element. Definitely built for professional usage, but also includes multiple safety features for enhanced safety and productivity for the average semi-professional user.This Milwaukee Rotary Hammer is the perfect tool for chipping thru concrete, rebar, etc. and delivers quality and consistency even under the roughest circumstances. One recommendation would be to make this tool usable as a corded hammer, as compared to being totally cordless. Otherwise, an awesome tool that I would recommend without hesitation to all Hope Depot shoppers looking for the best tools available.

    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.

    It’s built like a tank, However it’s a bit heavy I don’t mind the weight, It gets the work done effectively, And it met my expectations,
