    Listen I have a degree in electrical engineering. I think I know what is power is and I know what the scientific meaning of work is.

     

    If your battery has 200 Wh of energy into it, you are going to produce 200 Wh of work out no matter what the voltage, if we are neglecting what you are loosing in term of heat. It doesn't matter what voltage your tool is. Your battery will always have the same amount of energy inside of it. You can't create new energy out of thin air just by switching the voltage.

     

    If you are drilling the same hole with a 20V or a 60V drill, you are going to need the same amount of energy (again if we are neglecting heat losses which could be higher given a more powerful tool). The voltage has nothing to do with the energy required. One tool will complete the job faster than the other but your batteries will have lost the same amount of energy at the end of the job.  It's basic thermodynamics.  

     

    Considering your degree, I would assume your working knowledge is greater than mine, but ignoring losses due to heat seems like it wrecks the analysis.

     

    Energy loss due to heat is energy that isn't doing work, and higher amperage is what causes that heat loss. So with higher voltage, you can use less amperage, which means less energy loss due to heat, which means more of that energy is going towards doing work. To me, it's not about a bigger tank, it's about not having a fuel leak.

     

    All that is to say that higher voltage tools can push themselves harder without hemorrhaging power. But again, I defer to your expertise.

  2. They are good big box store tools, like Dewalt and Makita. On average, they are on par with those two. They do cordless lighting better than just about everyone but that's really the only category they clearly lead in the 18/20v arena; maybe in reciprocating saws as well. They are good about putting rafter hooks on stuff if that matters to you.

     

    They do 10.8/12v better than just about every one else though.

     

    I am in the m12 system and it's pretty good, but I do not like most m18 tools I have tried. That is totally preference though. Your mileage may vary.

    It's actually quite funny really. England turns an inhabited continent into a criminal colony (mostly destroying the historic inhabitants in the process).

     

    Couple hundred years later, that 'colony' outranks it in livable...ness.

    England is great at taking inhabited land and mostly destroying the inhabitants, and then making that land more livable than England. Exhibit B: Canada

    not sure who would pay that much for 3.0ah when you can buy 5.0ah for same price, or way less if you buy on ebay.

    The weight you save might have the same value as 2.0 Ah. I mean, not to me, but to someone... I guess?

    If you go to Dewalt web sites..you will see them compare the latest other brand tool and same size battery directly against their own...unlike Milwaukee last year comparing the flex 6ah against the Milwaukee 9ah.....obviously they had to...we see Dewalts 9ah is superior........I think Dewalt does fair test

    I think the reps probably know a LOT about the competition and aren't brainwashed at all.  They're PAID to downplay the strengths of the competition and the weakness of their offerings, so they might come across as kool-aid zombies sometimes when they're talking up how their offerings are 400% better than anything else.

    Milwaukee is a marketing company that sells tools. I wouldn't trust any of their tests, or most of the things their employees say (I mean Dewalt is hardly innocent in this, but their graphs and "stats" are at least not blatantly misleading). That being said, these are clearly good quality boxes. Being able to stack half sized boxes onto the larger ones is pretty cool.

  6. I personally like Dewalt's hammer drill more than Milwuakee's. I don't see the transmission sticking as a big problem. Mine has stuck once since I've owned it... Milwaukee drills feel like that have more wobble in them to me, but it could just be the ones I've tried. I've never used Bosch's but if it's anything like the rest of their tools, it's probably good.

     

    All three brands have a cordless multitool. I like the Dewalt, but from what I understand it is inferior to Bosch's starlock multitools. MIlwaukee's is apparently very out of date. 

     

    Honestly, you aren't going to go wrong no matter which of these options you pick. I don't know if in-store demos are a thing in Ireland, but that might be the best way to make your choice.

    I saw this saw (lol) a few weeks ago. It's basically a DWS535 form factor flexvolt saw (rafter hook, etc). I was told the the motor is identical to the DCS575. Battery pocket sits in front of the handle. I'm guessing we'll see an announcement soon. 

    Is the motor not brushless?
