Steve Maxwell: Good Morning!
Thanks for your note, and thanks for watching. I would have like to use the
same log, but I bored way too many holes for that. In terms of consistency,
all logs were sugar maple, cut live and at the same time. For what it's
worth, all logs were visibly identical, and since there were so many of
them (about 18 in all), I think any inconsistencies would have been
Is there anything in particular you'd like me to cover in future videos?
Braden K: Thanks Steve, best video yet on youtube! Very professional. Holy cow I cant
get over how well the vid was put together, tech, audio, visual, etc. You
are the man, I will for sure sign up newsletter. Have you ever though about
becoming the next "Home Improvement" icon? Tim Allen would be proud LoL.
EarthPersona: Very good explanation.
Ростислав Искандаров: Driving circuits of brushless drills are much more complicated and
expensive, There is a great possibility that it will die(nothing perfect!)
before a motor and gears. Thats the problem!
In Russia there is no chance to repair Milwaukee stuff, not paying 80% of a
new drill price, and warranty does not help)). So we prefer cheapest
brusched drivers or HILTI(which is undoubted)
wettosixecho: damn your voice is clear as freak dude crap i also thought i was watching
this in 4k until i hovered over the settings and saw it was on 480p freaking
mind blown great vid
Trueskills23: Makita invented brushless technology on powertools in 2003 so why are you
promoting milwaukee like if they did???
Jared McAllister: Great video, great breakdown of the different motor types. I'm looking to
purchase a cordless 18v/20v drill. As a novice, it's been tough weeding
through all this terminology. Brush vs brushless, now they are throwing
18v vs 20v.
May C: Thanks for your clear and concise explanations! Do you have a vid comparing
both brushless and brushed Milwaukee?
Tyler Fu: It sounds like a brushless motor in a power tool is essentially a AC motor
(not unlike an induction motor) that uses computers to vary the frequency
of the AC line (converted from DC) to change its speed. The problem is if
the circuit breaks, then the tool becomes worthless. There are VFD
available out there to allow people to run 3 phase motors on a single phase
power source (and probably even DC, since VFD always converts the AC into
DC anyways), however they are a separate module so if that breaks you can
always replace it. DC motor brushes on the other hand are easily and
cheaply replaced. I can't say the same for the computer module of a
brushless power tool...
Collin Cuoco: I would put a Metabo brushless drill up against any of these any day.. Try
one out Steve.
jollyandwaylo: The test would have been a better comparison if a brushed DeWalt was
compared to a brushless DeWalt. Maybe the brushed Milwaukee is better than
the brushed Dewalt or Makita.
Jair Graff: muito bom!!!
Patrick B: Thank you for the great explanation and tests. Your video is very clear and
josh33025: They're really all 18 nominal volts and have 20+ volts right off the
SPAHN MAN: The reason the brushless beats the brushed is heat. Brushed motors get
hotter but if you use each drill like you normally do, a couple screw hear
and there where each drill doesn't get hot you will see no differance.But
drop a brushless from 10 feet and that drill won't work but the brushed
Svet Plaichum: is usefull or not ?
If I take the motor of Milwaukee to become a robot motor?
Dummy Box: Thank You. I now understand.
Matthew Moody: http://dewalt.com/tools/cordless-drills-drilldrivers-dcd790d2.aspx
Can you do tests for the new Dewalt Brushless drills?
Spekka: Wow, I knew that brushless drills are the thing right now but never really
quite realized that they are actually that much effective. And they sound
so much cooler! Thanks! Great video!
Greg Greavett: Nicely done video Steve.Have you compared the Milwaukee 3ah battery to the
new 4ah to see the results?
lika sumboodi: Fub
lika sumboodi: Try the new METABO BRUSHLESS. craps on everything
Standard Nameo: Nice video! I can listen to you for hours!
Jason Patterson: Your arms have got to be tired. Great review, next Christmas brushless
will be all the rage even for DIY'rs. Even DIY folks use their drills
quite a bit and based on your test it would be money well spent.
Perhaps later do a test with a few different materials. Brushless is
supposed to last much longer when being used for screwing into softer
woods, etc. Brush based motors are all or nothing, the brushless motors
have a logic that only uses the amount of power needed, hence the extra
cost for the circuitry. Once again, great video.
quickguesswho: finally there getting brushless... I use a lot of rc electric cars and
trucks... and always wondered how come they dont have brushless power
no name: I think that the results would've been even further separated if the load
wasn't so heavy. For instance, a job of running short decking screws for
hours on end.
Nicholas Dixon: very good video. i like how you visually explained the difference between
brush and brushless technology. looking forward to a brushless bosch
Armando Murillo: Finally a straight to the point video , nice job .
SPAHN MAN: The differance between brushless and brushed is heat the brushed gives off
more heat when doing non stop applications but if you use your drills
normally with drilling a little here and there there won't be that big
TheJELLIBN: Great video Steve
Yevgen6R: Thank you for tutorial!
Te Boz: Enjoyed your video. Only wish you had picked ''one'' log that was big
enough so that you could have drilled all your test holes in the same log
instead of multiple ones. Just because I have had logs with different
density that cut at different rates with my chain saw. (103 kg/m3) 0.6 -
0.75 ....(lb/ft3) 39 - 47 [ from Wood Densities Chart found online ] I
know...picky,picky, picky :-)
VVK ZV: Thank you very much for the video and good explanation!
if you ever find "Makita vs ..." in Youtube you will find that Makita
looses usually (fewer holes/bolts, even smoke on overload), that confused
me, I suspected the authors in false play. I guess that all top-brands
should have comparable results.
I'm not Makita fan or expert, I have just a 14.4V drill and circular saw,
but It seems that your video is more trustable (averaged data costs much!)
By the way, what is your opiniton about the realiability of brushless tool
vs brush one? Can extra electronics cause extra weak points, or not?
Jacob Davison: Really helpful video. Would really like to see how the makita brushless
drill holds up to the test.
3091752: Milwaukee brushless vs Dewalt Brushless
Rob Bush: I am a Plumber/Gasfitter and Live in Australia, Just would like to know if
Our Models are the same as yours? I am looking to Buy a New 18V Impact
Hammer Drill Driver. I am thinking about choosing between The New Hitatchi
18V 4.0AH Brussless, The Milwalkee 18V 3.0AH Brushless , The Panasonic 18V
3.3AH with Brushes or the Bosch 18V 3.0AH 4 Pole With Brushes... What Would
You Reccomend ?? Thanks. Rob.
Jeff Jordan: Great Video. Keep up the great work
John G: I would like to add that most of the efficiency gains aren't from the lack
of sparking and friction from the brushes as you put it. These motors
aren't really DC motors they are similar to a 3 phase AC motor. And because
of that they rely on a digital motor controller to vary the timing and
phasing of the voltage going to the motor. The variable timing is where the
power and efficiency really comes from. A light load test (like driving
screws) would probably show a bigger difference yet.
diglettdigdig: Nice video. However, wouldn't it have been more accurate to compare a
brushed and a brushless drill from the same manufacturer? Just a thought.
AndreasC81: Aleks: That was the point with the test, to see how much better brushless
is to brushed.
Steve Maxwell: Yes, I have no doubt that brushless motors are cheaper to make, but as with
all new technology, there are development costs to cover for a while.
Thankfully competition will drive prices down in time, as they always do.
Tools are at least 50% cheaper today than they were when I began using them
in the early 1980s, even for tools that are much better quality. Thanks for
Steve Maxwell: Hello Dav, Thanks for your note. The self-feeding bits I used offer a
pretty even feed rate all on their own. I wasn't actually pushing the bits
into the wood, but just allowing the pilot thread to pull the bit in. Feed
rate was quite consistent this way. All the multiple drilling sessions I
ran also helped to smooth out the results. Thanks for watching! Bye, Steve
juzi68: How new is brush-less? European drill makers have been using it for many
years. Why the omission? Ignorance or deliberate obfuscation. I hope it's
the former. The drilling you performed is a little non-nonsensical, as
wired drills and proper heavy construction tools like Hilti (among others)
are more suited I suppose my bone to pick with your "review" is this: if
you're going for the professional presentation, speech pattern and look at
least be thorough and well informed. Cheers mate!
Steve Maxwell: Hi Aleks, My thinking was to compare brushed-to-brushless with this video.
Later on, when there's a wider selection of brushless available, I'll test
brushless-to-brushless. Thanks for watching, Steve
coptool: We did a similar 18v drill test into concrete with 4 brushless & brushed
motor drills with the same outcome however I like your presentation much
better. Nice video.
Wayne Burgess: My other concerns are you can change the brushes in a drill in your lunch
break and carry on working a brush-less breaks down and you are shelling
out for a new motor. Also Milwaukee give a 5 year warranty so if the 10
times motor life is to be taken seriously will they now have a 50 year
wayne burgess: Hi Steve, I have now tested these side by side and the Metabo blows the
others away Pal. Any saving on battery drain is more than made up for in
the extra amp hour capacity in the batteries. Also the 4 pole motor is so
powerful the application gets done quicker. Mid range drills on mid power
applications the brushless wins though, an example being small diamiter
holes or short screws the brushless then leaves the brushed behind it just
like a car with better fuel consumption. :)
Aleks Russian: Why not add the Makita Brushless drill, seems like an unfair bias towards
milwaukee, Makita makes a brushless drill and impact driver. Obviously the
milwaukee will win.... Its like comparing a 2006 dell laptop to a 2012 HP
and saying HP is better LOL
animal79thecat: A good informative test sir. Have you had a chance to get your hands on the
new brushless Dewalts yet?
