Tino Detres: The revolving part of the motor is called an armature.
oobaka1967: One thing puzzles me. The brushed drills were both lithium ion which shouldn't slow down with low power. Every li-ion battery / drill I've used would just stop.
Hamza Halal: I just bought dewalt brush drills dcd771 and dcf885 they spark and smell like burning, I'm not rich and all I could afford was $200 did I get screwd should I return them and save more money for something better I'm hoping this drill and impact driver will last me for a long time will they? any suggestions
Home Innovations 101: This is the best video I have seen that approaches the subject of brushless vs. brush motors in drills. Thank you for clearing up the confusion and making it VERY clear which drills are superior.
Colin Crook: Not very scientific! The drills tested should be of the same brand with consistent material to be drilled.
TheRipper999: Hmm. 1. Were the drill batteries new? Not sure if usage would wear down the charge. 2. Comparing across brands may not be the best comparison. 3. Regardless of those points the numbers do show the brushless drill is superior. Wonder how durable and how long the drill will last though.
SquirrelFromGradLife: except the batteries are never 3 amph even brand new..
fethulgulub: nice video
shellz150: Milwaukee was on mode 1
Albert Tremblay: great video. My main concern with brushless motors is durability. Not how long they last so much as how difficult it would be to repair them. thanks take care
Michael Hawthorne: yes I agree with others that was an excellent video, very informative and professionally edited too.
Bigchuck678: I think a better comparison would be to compare the same brands brushless vs brushed drills. For example Milwaukee's best brushed hammer drill vs their brushless hammer drill to see the difference.
I Plumridge: One of the best explanations of what a brushless motor is and how it works. Great video - thanks for taking the time to do your comparison. Have a sneaking suspicion I know what kind I'll be buying in the future.
MrHollick: Great test and video! I wonder how a Dewalt brushless would hold up in the test?
lolnepal: Thank you for explaining this. There were two identical ones in a store and the seller could not explain why one was more expensive. Now I get it. Thank you again. Your review is also detailed. If someone is looking for 20V vs 18V having exact specification, which one would you recommend and why ?
Hamza Lateef: nice video and hah! the makita had beat the new dewalt dcd985
David Handley: What an excellent well presented unbiased review! These type of reviews can easily get bogged down in too much detail, and they often only add to the confusion. Thank you. Cheers from down under.
FoodOnCrack: Damn you have one of the smoothest voices i have ever heard.
Gabriel S.: Coming from an RC airplane background, back in the day fuel/glow engines were more powerful than electric because all we had were heavy and powerless brushed motor/nicad setups. Those days of electric flight sucks.
Nowadays thanks to brushless motors electric RC planes are pretty much superior in every way to their fuel/glow power brethren; they fly faster, longer, are lighter and more reliable than Fuel/glow setups, except arguably for the realism or scale planes because of the smoke and sound.
