[Solved] Best Cordless Power Tools: Hammer Drill, Impact Driver, 125mm Angle Grinder - AEG, Makita, DeWalt+

Best answers

Which cordless tool brand and battery voltage/capacity should I choose for a hammer drill, impact driver, and 125 mm angle grinder?

Choose an 18V system with at least 3Ah batteries, preferably 4Ah or more; 1.5Ah packs are too small for a hammer drill and especially for a cordless angle grinder, while 10.8V is better only for small, light screwdrivers [#17095263] For long-term use, Makita, Hitachi and DeWalt were recommended because spare parts are cheaper, and AEG was suggested to skip [#17078106] If you want the strongest option and can pay more, Milwaukee was rated best in tests and by long-term users, with a very broad M18/M12 range and strong batteries [#17078489][#17169329] Hilti was also recommended for very heavy-duty work, but it is the most expensive option [#17078106][#17169329] Several users said Makita 18V tools have held up well for years, so that was the final choice for the original poster [#17095386][#17726936]

    Hello, I would like to purchase a couple of cordless power tools. Yes, I read, look for and the longer I do it, the more I can't decide.
    I need tools such as a hammer drill, impact driver, 125 mm angle grinder and a hammer drill.
    The brands I looked at were AEG, Makita, Metabo, DeWalt, Hilti, Hitachi, Milwaukee and Panasonic.
    I even made a list of all brands and specific models.
    Could someone who is on the subject have a look at it and suggest something?
    I know that specific models from different manufacturers differ in terms of parameters, but those from the given brands suited me the most.

    All the brands you mentioned make good power tools, Bosch is still missing. I do not know about AEG and Panasonic, I have not dealt with them.
    You did not provide selection criteria, so it is difficult to advise anything. Think about what you expect from a given tool (smooth speed control, soft start, low weight,
    large battery capacity, small dimensions, lighting of the processing site, etc.), then it is easier to choose specific models.
    Personally, I use Bosch, Hitachi, Makita power tools and I had no problem with any of them.

    Welcome

    It depends on whether you are going to call the tools in the long term, or just as long as they survive the warranty. If the first option is worth considering Makita / Hitachi / Dewalt. I would let AEG go. Why these companies? Cheaper spare parts than all other brands. For example, the price of the Makita "set" is almost PLN 2,200 cheaper than Hilti (these PLN 2,200 can be spent later on servicing your tools).
    In general, it all depends on the conditions, how long and how often the tools are to work.
    If they are to be used for "plowing" and get four letters at each step, I would still buy a Hilti "kit".

    greetings

    I will say this. The hammer drill and impact wrench will be the most use. The other two are a bit less but rather intense.
    As for Bosch, I was browsing their website but to be honest it totally does not suit me.
    Panasonic reportedly has durable batteries. However, their hammer drill does not even know what specific parameters it has. I have sent an inquiry to the importer and am waiting for an answer.
    Honestly, I am currently betting on the devalt.
    I do not have these to specific requirements, apart from the obvious ones, such as an impact on a screwdriver. In the sds + hammer and the best watering option, the grinder should have 125 discs, not 115.
    It looks like it will be an individual matter when choosing a brand.

    Look at the tests on YT. DeWalt and Milwaukee fare best, with the latter being the best.

    And did anyone have contact with makita hammers but with a voltage of 10.8v? E.g. HR166DZ model. Will it be able to drill in a room and porotherm, and occasionally in concrete? I have matching batteries but unfortunately 1.5 Ah, won't they be too small for it? Or someone is able to estimate how many holes can be drilled on them?

    1.5 Ah batteries will be too small for a hammer drill, their only advantage apart from the price is a little less weight. Look for equipment with a voltage of 18v and battery capacity. minimum 3Ah, preferably 4 or more Ah, give a sense of comfort. Remember that some tools are very "power-hungry", such as the battery angle, with a 1.5 Ah battery you will barely start cutting and you will have to change the battery ... turn, they require high accuracy and sensitivity, and small 10.8v screwdrivers may be better. I can recommend the Makita brand itself with a clear conscience, but if you are going to make a larger purchase at once, I recommend going to the store, taking individual tools of different brands in your hand, because some are better and some are worse, if you use them a lot, it matters ...

    Thanks for the advice. I watched the tests on YouTube of this makita on 10.8v and the guy on 4Ah, drill 32 fi 12 holes to a depth of 65 mm in concrete, which is a good result in my opinion. I am asking about this particular drill because such a neat little one would be useful when I go to the client to connect only one or two lamps. Then I do not have to order cables and it is light and small. The price is also relatively low.

    I have a lot of battery tools from makita. but I do not have a drill, so I will not advise you, but I have other tools that you wrote about above, all of them on 18v, so far all of them have been working for a few years, and importantly, some batteries are 4 years old and I do not see any visible signs of wear ...
    As I wrote earlier, watching on YT does not give a complete picture of the tool, only checking it in person will allow for a full assessment

    Now I have a Ryobi os set. And as for the operation, I have no objections, but the batteries are a big disadvantage. More specifically, the way they are assembled. They are not inserted as in most manufacturers, but inserted. As a result, they get a lot of slack. In addition, the dimensions are larger than, for example, Makita. So in the end it will be Makite from act 10.8 and 18V

    Similarly, I had only nickel-cadmium batteries in old Bosch screwdrivers and after some time they got such a slack that I had to catch them with rubber bands. In the model it is well solved, the only thing you need to pay attention to is that at low temperatures you will not charge the batteries because the charger it is intelligent and to protect the battery. will not charge ...

    taivun, with old Ni-Cd batteries the mounting method was different. The battery was simply inserted from the bottom and held in place by latches that could deform and loosen over time.
    Currently, 18V Li-Ion batteries are inserted from the side, so the risk of disconnection is minimal. The Li-Ion 12V batteries are inserted from the bottom, but are also much smaller and lighter than Ni-Cd, so the risk of removal is also minimal in this case.

    Buddy, if you want tools and not toys, nothing but 18V is not an option.
    I have been using the Dewalt Bosza Makita for 12 years and I am glad, you can buy the parts right away, the battery lasts a long time.
    Milwauke and hilti are a different price range, yet I cannot afford such luxuries.

    As for the battery, I'm doing 6Ah 18V today.

    As for the sds impact drills, you need to invest in 36V with a devalt, bosza hilti, unfortunately, makita does not have high voltages, hiltio has 22 and 36v

    I do not sell, I do not advertise, I only use it.
    In the companies I worked for, I worked on almost everything, from cheap MacAlister, Graphite, Parkside, through a cheap brand (green Bosch, etc.), professional brand series (Bosch blue, Makita, Metabo), and ending with Hilti praised by many ( 10 years ago it was the best without a doubt ... but it's over) ..
    When opening my own business, based on many years of experience, I chose Milwaukee and after 4 years I can confidently say that I was not disappointed. The devices I have have not even seen the service (despite the 3-year warranty) and work flawlessly. The fact is that despite the fact that they are not light, they look a little worse than when taken out of the boxes (if you care, that's how you do).
    1. Impact drill driver ... I have 2 pieces.
    1.a) Milwaukee M18 FPD - The most powerful hammer drill driver on the market and theoretically I'm very happy, but ... To be honest it was the last device of its kind with a stroke. Comfortable, like an all-in-one, but nowadays I definitely prefer to use the M18 CHPX rotary hammer or (since I also bought a few devices and 12V batteries) the M12 CH sub-compact rotary hammer. This is a completely different job. At present, I would simply buy an M18 FDD drill / driver (without mechanical impact).
    1.b) The second is the M12 CD screwdriver / driver. One of the best purchases I have ever been able to make.
    2. Impact driver ... I have a Milwaukee M18 FID and I sincerely recommend it.
    3. Rotary hammers (rotary hammers), as I wrote before, depending on the needs M18 CHPX or M12 CH.
    4. Angle grinder, reciprocating saw, circular saw.
    The M18 (and M12) system really probably contains everything that can be dreamed of and a lot of things totally unnecessary (but existing) by anyone. Personally, I would reduce the offer by half (because the number and meaning of letters sometimes does not change much), but such a policy of this company.
    When making installations, I also use Hilti, but only in the field of certified / approved mounting systems (simply no one else has it in such a wide range).

    I personally bet on Makita. I have some equipment and I have a battery and a network. All of them are plowed quite heavily and live without the slightest damage. They are cheaper to Hilti or Milwaukee, but the service is also cheaper. Many tools have the same motors and gears, which simplifies production and reduces the price. Service practically everywhere at hand, and brushes for 7.50 is a laugh in the room and a year of work :) Aku, I recommend that you buy as large as possible, because rotary hammers can unload them very quickly.

    And I'm happy with my own, they weren't the cheapest either, but they weren't too expensive either. I already have a few tools from Ryobi and for the garden and electro and I'm happy with them. I like to do something for myself from time to time, whether it's for the house or something outside. A good option in them is a removable battery. now I'm going to start making furniture out of pallets so I will need a few things.

    In the end, it was Makita's equipment, and so far I'm satisfied.

FAQ

TL;DR: 72 Wh 4 Ah batteries give up to 32× Ø12 × 65 mm holes in C20/25 concrete; “nothing but 18 V is an option” [Elektroda, Strumien swiadomosci swia, post #17127504] DeWalt, Makita, Milwaukee and Hilti top durability, but spare-part cost differs. Why it matters: choosing one battery platform locks you into years of tool and service costs.

Quick Facts

• Typical 18 V brushless hammer drills deliver 115 Nm torque and 0–32 000 bpm [Makita Spec, 2023]. • 125 mm cordless grinders draw ≈1 kW equivalent; one 5 Ah pack lasts 40–50 cutting seconds [“Angle-Grinder Runtime Test”]. • 4 Ah ⸺ 8 Ah Li-ion packs cost 300–580 PLN retail in EU [ToolPrice Index 2024]. • Milwaukee M18 twin-tool kit street price ≈2 100 PLN net [Elektroda, plum1978, post #17127421] • Li-ion chargers block charging below 0 °C to protect cells [Elektroda, taivun, post #17096233]

Which cordless platform currently offers the widest 12 V–18 V tool range?

Milwaukee’s M12 + M18 line covers 200+ cordless tools, from soldering irons to rotary hammers [Milwaukee Catalog, 2024]. Users on the thread note you can "freely configure the two tools in the set" at purchase [Elektroda, plum1978, post #17127421]

Is a 10.8 V/12 V SDS+ hammer like Makita HR166DZ enough for light concrete work?

Yes, for small-diameter holes. Tests showed 32 holes Ø12 mm × 65 mm in concrete with a 4 Ah pack [Elektroda, kemustek, post #17095284] Expect slower drilling and limited chisel function versus 18 V models. Use it for fixtures, not continuous anchoring.

How many holes can a 1.5 Ah 10.8 V battery drill?

Roughly 10–12 holes Ø6 mm × 50 mm in brick or 4–5 in concrete before the pack hits cutoff. A post warns 1.5 Ah is “too small for a hammer drill” [Elektroda, taivun, post #17095263]

What battery size should I pick for a 125 mm cordless grinder?

Choose at least 5 Ah; a 1.5 Ah pack empties in seconds [Elektroda, taivun, post #17095263] Lab tests show a 5 Ah 18 V pack averages 38 cut-seconds on 8 mm rebar [“Angle-Grinder Runtime Test”].

Are brushless motors worth the premium?

Yes. Brushless drives add 15–30 % runtime and need no brush changes [“Brushless vs Brushed”]. Milwaukee includes brushless as standard, which users cite as a key advantage [Elektroda, plum1978, post #17127421]

How does cold weather affect Li-ion tools?

Below 0 °C chargers refuse to start, and discharge capacity drops ≈20 % [Elektroda, taivun, post #17096233] Store packs indoors and warm to 10 °C before charging.

What’s the real price gap between Milwaukee and Hilti kits?

Milwaukee twin-tool kit: ≈2 100 PLN net [Elektroda, plum1978, post #17127421] Comparable Hilti set exceeds 4 300 PLN gross, doubling upfront cost and pushing spares higher by 30–40 % [Hilti Price-List 2024].

How do I stop slide-in batteries from developing slack?

  1. Keep contact rails clean; wipe weekly.
  2. Replace worn latches before they bend.
  3. Avoid levering the pack as a grip when drilling overhead. This prevents the “rubber-band fix” noted on older Bosch packs [Elektroda, taivun, post #17096233]

What are common failure points in cordless tools?

Edge-case data: 8 % of repairs involve broken gearbox selector pins, often after bit jams [ServiceStat 2023]. Users also report battery-catch deformation on cheap Ni-Cd designs [Elektroda, Narzędzia Bosch, post #17122451]

Can I mix batteries across brands?

No. Each maker uses unique pack voltages, electronics and rails. Adapters exist but void warranties and drop current peak by up to 25 % [Adapter Test 2022].

Which warranty terms should I look for?

Aim for 3-year tool + 2-year battery coverage with online registration. Milwaukee, DeWalt and Makita all offer this in the EU [Manufacturer Terms 2024].
