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?
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.
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?
Standard Nameo: Nice video! I can listen to you for hours!
Mike Hoover: 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.
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!
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
Nicholas Dixon: very good video. i like how you visually explained the difference between
brush and brushless technology. looking forward to a brushless bosch
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
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.
Armando Murillo: Finally a straight to the point video , nice job .
Greg Greavett: Nicely done video Steve.Have you compared the Milwaukee 3ah battery to the
new 4ah to see the results?
lika sumboodi: Fub
Yevgen6R: Thank you for tutorial!
TheJELLIBN: Great video Steve
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 :-)
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
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
garthqueen: A good informative test sir. Have you had a chance to get your hands on the
new brushless Dewalts yet?
Pang Bard: Thank you
Steve Maxwell: Hi Again Pololous3, Let me check on that Metabo thing again. I thought it
was owned by TTI, but it may be that TTI just makes some of their stuff
these days. Stay tuned for the definitive answer on who owns Metabo . . .
Steve Maxwell: Hi acsfloorcovering, I considered including other brushless in the test,
but there weren't a lot of comparable models available when I ran the test.
Running brushed against brushless seemed like the way to go. My plan is to
run a brushless showdown when a few more brushless drills come out. Thanks
for watching, Steve P.S. In my preliminary testing so far, Milwaukee
brushless offers significantly longer run time than any other brushless
drills, all using the same amp-hour batteries.
Steve Maxwell: Hi Wayne, I've never ran a test with the Metabo 4-pole versus Milwaukee
FUEL. How does the run time and power compare numerically? As for motor
life, I know that typical brush-style drills can bore about 10,000
1"-diameter holes in 1 1/2" construction lumber before they're toast. I
know of brushless drills that have topped 405,000 test holes of the same
size and are still going. That 10X figure is understated, though it doesn't
translate into 10X warranty that I've ever seen. Thanks, Steve
dav parksoh: great video Steve - were you monitoring the pressure force in a precise way
to ensure that the same loads were applied to all 3 drills throughout the
duration of all 3 tests? To make this test more scientifically accurate, a
pressure meter measuring how many pounds of force you are applying to the
drills by leaning into them would be more accurate - your method is more
subjective - a engineer would place an exact pressure or force that would
be constant, thereby proving the drills' performance
Wayne Burgess: This makes the Metabo 4 pole motor very remarkable then because it is more
powerful and has run time equal if not longer than the fuel. :)
A Concord Carpenter: Well done Steve
POLOLOUS3: Holy crap, I just got the news feeds on it too. I'm overly excited. I've
got to get my hands on them even though euro is getting them first and no
news on the states.
Drew cronin: good to see an honest test done. one thing then to keep in mind is charge
time Makita 22min v 45 min plus total number would favor the Makita.
Shauns Erratic Behaviour: Indeed.. we've been using brushless and lithium battery technology for
years. It's nice to see manufacturers taking advantage of the power,
weight, lifespan and battery savings that RC guys have known for years
Bad Karma Vegas: Excelent video, very informative and it does an great job explaining the
WorkshopAddict: Great video. Very informative. From what I understand, the electronic
sensors in the brushless drills are the reason why the prices are higher
than brushed right now. Depending on what type of sensor they incorporate
into their tools will dictate the cost. I do believe that over time the
prices will come down and brushed tools will go away. Brushless with the
addition of 4.0 amp hour batteries will allow our work time to go up
dramatically. What a great time to be a tool freak.
danielross85: Awesome, now teach us how to mill those logs!
wayne burgess: :)
Steve Maxwell: I'm glad I checked. I was wrong on the Metabo ownership. TTI doesn't own
them. I was thinking of another European company. Bye, Steve
Shaine Falwasser: should have used the brushed m18 drill in the comparison just to see how
that stands in the ranking...but pretty good comparison...thanks
Steve Maxwell: I I thought of running the footage non-stop for all the drills, but I
completed a number of runs for each drill, and each run ran for quite a
while. I doubt that anyone would sit still and watch many minutes of a
drill going in and out of a log. For what it's worth, the numbers were
carefully gathered and honestly compiled. Ultimately, as the reality of
brushless tools is experienced by more and more users around the world,
there won't be any need for tests like mine. Thanks for watching, Steve
