Just did a test between the new bosch IDH182 18v hybrid impact driver VS the milwaukee fuel 18v impact driver to see which one is quicker
check it out to see who won
Like the side by side comparison Javier. Good video.
Thanks Javier, results as expected for me.
Its a little disappointing that the first impact drivers to have a socket anvil is easily beaten in the types of application which would use one, but oh well. still a great little tool.
Nice video.
Thanks guys

Yeah it is weird the bosch with the 1/2 socket drive doesn’t have more power. Maybe they did it on purpose as I’m sure they could add more power, maybe even add a switch so you can have more power with the 1/2″ drive but my guess is that idiots would take advantage of that and use it for the hex chuck and be upset when all their screws end up snapping, just a guess though
Dam it javier i been looking on youtube for a comparison with the new bosch vs the milwaukee(cuz i have that m18 driver) and of course u got it:) ur awesome bro..great job!!!! Love it:)
The bosch really struggled with the last lag screw… That kinda surprised me since it has a 1/2 drive u would think it had the power to get the job done. Thanx again javier
it was the same story with the previous (brushed) hybrid. I loved the idea, but was disappointed that my dewalt smoked it with lag screws. especially since Bosch have high torque claims and have liked to talk about the ‘torque losses’ associated with use of an adapter.
Thanks FrankieGarcia
@ Dwain, what makes the results more interesting is that the m18 used an adaptor for the larger 1/2 lag while the Bosch used no adaptor for the socket. So the m18 still had the edge even with the adaptor
The last test suprised me the most. The adaptor will cut down on torque some, not much, but it will be noticeable. Great video Javier.
I really appreciate the video but that is not a fair comparison. Yes both batteries have the same voltage but the 4ah pack has double the cells and double the amps to give the motor if it needs it.
That’s why I went with the speed test to make it fair. At first I wanted to see who had better runtime but I couldn’t do that with the difference in battery size.
Both Bosch and Milwaukee advertise the same stats regardless of battery size for these impacts so the performance is the same
Great tool fight Javier. Best one yet IMO.
It just goes to show that it isn’t wise to put all your eggs in the torque basket.
Excellent comparison man.

Your “speed” test is pulling alot of amps from the packs, and that gives the bigger pack the upper hand.
To put it more clearly, not only do batteries have an amp hour rating for capacity, they also have one for discharge rates. That fat pack will handle twice the discharge rate of a slim pack
Way to go. Made TIA front page.
I have a nearly new 2ah M18 I could loan you if you want to do a retest…
That’s awesome! Even DR99’s tool boobs made it on the front page, nice!
I believe that the results would’ve been the same even with the 4 amp hour battery. Milwaukee loaded their driver with a very high impacts per minute rate and that makes the most difference i’ve seen in my experience as far as speed over torque and rpm. Great video by the way Javier.

Hi Mike. I’ve heard this theory before but have never seen any proof (mathematical or empirical). Can you provide any?
I suppose many of us could compare certain activities (i.e. lag bolts with impact driver) with different size batteries (on the same skin) and time it…. maybe i will.
I think the confusion that is arising here is the difference between ah and ah/h. Ah ( amp hours) is the batteries capacitance or volume, for lack of a better word, of stored power. ah/h (amps hours per hour) is a draw or discharge rate.
I don’t think that the tools draw enough amperage to make a difference. If it was a high draw tool such as a recip saw or circ saw it would definitely make a difference. I don’t know how many amps the motors draw but i think the compact batteries can handle an 80 amp max draw. I don’t think an impact driver can draw near that much. If someone could find how many amps the motors draw we could figure out the answer.
I do know Milwaukee rates the tools differently if you have fat packs or skinny packs on the tool. It’s not a huge difference though
The compact Fuel drill gets 650 foot pounds with the compact battery while the XC packs gets you 725 foot pounds. The impact does not show any difference in torque regarding the size of the battery pack.
i did a little test regarding battery sizes over here: http://professional-power-tool-guide.com/power-tool-forum/index.php?/topic/3865-does-a-larger-battery-give-more-power-results-inside/?p=28858
Nice comparison. Even bosch has the extra 50rpm, But I almost sure Milwaukee will win that one. Because of the 4.0 pack and bigger pack seems like giving more cleaner power on impact driver than the small 1.5 or 2.0 packs.
Javier, is there any way you could do a runtime/power test with both on 4.0ah batteries? Or running the Milwaukee on 2ah? Wouldn’t have to be video’d necessarily (we trust you :)).The possibility of battery size affecting available power, and the Milwaukee possibly running better at the start of testing are really messing with my head! 😛

If you can’t, no matter. Still appreciate the excellent video!
Awesome job Javier! Way to represent yo!
I don’t have the Bosch ec tools anymore so the best I can do is retest the Milwaukee with a 2.0 battery . I need a 2.0 ah battery though.dwain wrote:

Nice video…and salute to Milwaukee … O0

I am not surprised at this result, I have 2 of the fuel impacts and Dewalt’s brushless 3 speed impact and Makita’s new brushless 3 speed impact (and the downshift model also) and I would agree that with #10×3.5″ deck screws that we use the Milwaukee is only marginally faster, but for lag bolts or large self taping screws (which we do a lot of) the fuel guns are the fastest every time.
I will say that with all that power comes a trade off, the fuel gun will countersink the head before it sucks the boards together which is a pain. The Makita gun has that one, as it seems the easiest to finesse and suck boards up tight if they are warped or curled.
