    Not in reality. I did a test the other day. I drained a 3, 4, 5 and 6 ah battery the other day and the 5 took 30 minutes longer than that. Only the 3 managed to come in at the advertised time. All others were way off.

    That's most likely because you drained em and they were too hot.

     

    Every decent charger ( of every brand ) first cools down the cells to a reasonable temperate to charge em. Charging too heated cells causes premature wear.

     

    If you charge cool batteries that's the only time advertised charge times will be correct.

    I just ended up ordering the aws vac. Fingers crossed that the $100 premium for AWS ends up being worth it for me. I’m gambling that it will be but with very low expectations. I need cordless dc for most of my projects and my dewalt 20v vac isn’t quite up for what I’m asking it to do. I’m hoping that mak will release an AWS adapter or that I can hack a Bluetooth adapter of my own for universal use with any of my tools. 

    Of that hacking up of the adapter works then let us know please :D

    That's some serious DeWalt bashing and total BS....I realize this is a Makita forum but damn dude..the only laser not to buy is Makita.... Buy Hilti, Bosch...for high end... DeWalt is great for under 400... total BS

    Joe, if you just compare specs you'll easily find that the DeWalt line lasers have some of the highest lack of accuracy around.

     

    I don't know feet and inches but in millimeters the DeWalt has a possible 3 mm inaccuracy for every 10 meters. ( Compared to 1.5 for most decent lasers or even 1mm for hilti/these Makita )

     

    So for any range larger then a living room the dewalts are way off. Can't even get them calibrated more correctly.

     

    Short ranges it'll be ok.

    I don't think its just an alternate design for the XRH07, the patent was just filed. I have a feeling it will turn out to be a 1 3/4" - 2" hammer. DeWalt has one coming out soon, i'd be surprised if we didn't see Makita come out with one next year.

    Ah yep it's a different patent. I thought it would be one of the 32 different ways of putting batteries on a tools like Makita usually do in their patent applications.

  5. Accuracy, real line laser instead of a prism laser, can be calibrated, receiver always works,  dials for fine movement, vertical lines cross in the center of the laser instead of ' outside ' the laser, mangetix dampened pendulum. Laser diodes/mirrors better protected if it falls.

     

    Altho if you just want ' green lines ' then the DeWalt will do

  6. Makita lasers do not suck. Not a single one. 

     

    The rotary laser SKR200 is a very basic unit but also very cheap. 

     

    The line lasers sk102/103/104 are all nice units that do what they have to do.

     

    The laser you mentioned above ( SK209 )  is a very high end unit .

     

    Now, 90 out of 100 people wouldn't even know ( or notice ) the difference between this and a cheapo DeWalt line laser so for most people there is no need to spend alot more money on this SK109 then on the DeWalt line lasers.

    I just got a pair of knock offs. I haven't used them much yet, but so far they seem to work just fine. I have a knock off Ryobi battery and that one has worked well for about 6 months now.

    You have any powerfull high drain tools to try them in ? ( And compare )

    In any case it's waaay heavier and pricyer than any corded model with the same power specs.

    And I suspect that the motor is not beefy enough because they tend to make these brushless motor smaller.

    I don't know if the cordless advantage is worth having these drawbacks.

     

    But the Dewalt 60V is brushless too. And I doubt that current commercial brushless motors are much more efficient. They are more like marketing bs. The Makita DHP458 drill for example is brushed  and produces almost the same torque as the brushless DHP481 which is also heavier.

    Including batteries it's exactly half a kilogram heavier then the corded model ( which is one of the strongest performers in it's class only equalled by hilti) . 

     

    What you suspect doesn't matter because the cordless is exactly as strong as the corded.

     

    You doubt that current brushless motors are more efficient ?  The 481 has 115nm hard torque compared to the 85 of the 458. That's 30 % more. It has higher rpm's also( 2100 vs 2000)and upkeeps it's rpm alot better under load. the 481 also drills more holes then the 458. And not just a few more but in a heavy duty situation ( big hole saws for example )  easily 30 % more.

     

    So.... 30% more powerfull, easily 30% more holes in a heavy application, more top speed and it stays higher in it's rpms during load......

    But you doubt brushless motors are more efficient.

     

    Abit of research before you say anything instead of ' suspecting ' things would help.

  9. Speed going up and down is most of the time the electronics/speed controller.

     

    Noone can tell you by phone what is broken or not.  A repair guy needs to see your tool, see it's behaviour and check for other things that might have broken/been affected.

    I don't understand how can a 36V tool have the same power as a 60V tool ?!

     

    The idea that more voltage gives more ( potential ) power is an old idea that was mostly correct for brushed tools. 

     

    Pretty much all tools these days are brushless tools. They are electronically controlled instead of using brushes for their commutation.

     

    For brushless tools the voltage and amperage of batteries almost don't matter.  You'll notice from the movie that the 18v milwaukee SDS max is some slower then the 36v or 54v SDS max hammers but not even close to double as slow ( as the voltage would imply ).

     

    That leaves us, customers, with no apparent and easy way to compare modern tools.  ( Where 10 years ago with brushed tools  the voltage and amps were an indicator of what too expect. )

     

    http://www.toolboxbuzz.com/cordless-tools/reciprocating-saw/cordless-reciprocating-saw-high-capacity-head-head/

    Here is another interesting comparison. 18v milwaukee and 36v Makita recip clearly perform better then 54v flexvolt recip saw.

     

     

    We have seen ( from examples in practise ) that voltage and amps of the battery don't tell us anything about the performance we can expect.

     

    A thing you can compare is the total available energy in a battery setup. Since the voltage and amps don't matter we can start comparing the total energy capacity of a battery setup. Both milwaukee with a 18v 9amp battery and DeWalt with a 54v 3amp amp have a total capacity of 162 watt hours ( volt X amps ).

     

    You can expect somewhat equal potential performance from these batteries.   DeWalt uses newer and more efficient cells in their big flexvolt which gives them a few percent advantage. Higher voltages also give a few percentage efficiency advantage.   But milwaukee just makes a better sawzall then DeWalt. The better tool will perform better in the end even if the DeWalt has a small battery advantage.

    What did you feel were some of the video shortcomings? This isn’t actually a tool I have a personal interest/expectation in getting I just happened to come across the review.

     Thé 11 Joules of the Makita are wrong ( even tho it says so on the Makita USA website )

     

    Stating the Makita as a 10 amp capacity. ( If it was 18v ...yes. but it's 2 batteries in series so it's 36v 5 amp )

     

    Stating the flexvolt as a 9 amp. On a flexvolt tool it's 3 amp.

     

    Kinda disagree on the point giving for run time. DeWalt and Makita do exactly as many holes so points should be even.  If you're drilling holes you wouldn't care what numbers are on the battery. The amount of holes drilled on a charge is what matters.

     

    And ( I could be wrong here because of limited experience ) but I don't see the use of a drill only function without hammering on a 7 kg SDS max breaker which coptool praised the DeWalt for.

     

     

    Just felt more like a random YouTube test because of the inaccuracies then a decent review from a power tool website.
