How a cordless drill works 

The quality of these breakdowns always makes me happy. You do such a nice job explaining things! Keep up the good work - I would be proud of this if I were you.

Great video. Since you already have the 3D models created, you could make additional videos on common failure points and repairs for the tools you talk about. Like calibration for the torque wrench. You could make a video about replacement of brushes for a brushed drill, or how dirt and grime can get in the way of the brushes even without them being worn down. For a brushless drill you can show how a capacitor is needed for that boost of energy to get the drill starting spinning. If the brushless drill isn't spinning, or it's overloaded you can show what part inside is the first to start heating up and smoking. I think you can increase the value of the 3D models you create into much more than just an explanation of how it works. There's value in knowing how something works, and also knowing how to fix it. You have such detailed models that I think you can do both in a beautiful way.

You produce criminally underrated content!

Great video. It's incredible how much simple but great design is hidden is such a ubiquitous tool.

Thanks for this, I learned a lot. The first half felt kind of like what you would need to show a grown person who never used one how it works, but the second half really broke it down. My old machine is starting to smell and burn up, and now I know that the brushes (or probably the motor itself) would need to be replaced, but as long as it's still working I'll keep on keeping on.

You guys are one of my all-time favorite channels on youtube, you've earned my subscription. Keep up the good work!

On some cheap junk drills those gears in gearbox are made out of plastic, the outer ring is some pot metal. Doesn't take much to break it

Love those videos! Do you think you could do a chainsaw next? :)

This video is a true masterpiece of educational content

👍👍👍 highly appreciated explanation very super and simply

Nice demonstration 🎉

Thank you sir. I was doing the calibration of these kind of electrical screw driver but did not know the inside mechanism. Now I got to know sir thank you so much. Please make some videos on working principle of Torque sensors

Amazing video, thank you for this content, this is really high tier and underrated.

I mistakenly look it as brushless drill instead of cordless drill. Anyway, it is a good understanding of each parts and how they work.

Excellent explanation. Thank you for your brilliant video. 👏

Awesome stuff! Can you do a pressure regulator next? Many welders will thank you

2:30 I’d say 12-24 volts. There are enough mainstream 24v lines to include them even if some are stacked lithium (LiPo).

Great explanations

Keep uploading more videos please ❤❤

now i know how a cordless drill works. sweet

more, i need more

beuteful

Love your videos

Very interesting, but it doesnt explain, when the ratchet no longer works. It still drills, drives releases screws. But the ratchet assembly section, no longer engages. It just turns around now. Any one got any ideas why it's not working

thank you so much .... what is this app looks so amaizing can i use it and make 3d design??? ❣❣

I thougt the switch on top was to change to hammer action

Cordless drills are a wrist~breaker! Use with Caution ~

Why does your voice sound so familiar to Pierre Gasly's ? 😂

How does braking work?

Why don't the company build this design on bigger electric drill.

👍

How a "cheap" brushed cordless drill works*

You should cover the circuitry of the PCBs. It would be great to see how they work.

Really great electro-mechanical details. Didn't know it used planetary gears, or that the speed setting affected torque! Extremely practical info as a mechanical design engr.

I always thought the forward reverse button was purely mechanical 😂

im a simple man. I hear planetary gears. I press like

Amazing overview of these drills, though individual brands may have some small differences i appreciate how you made this broadly applicable to pretty much all of them!

I’m a new mechanical engineer and these videos really help me understand my job much better

Loved the video! Kinda wished the internal mechanics of the motor itself were covered, as I'm curious about the difference between brushed and brushless motors. If that's covered in another video though, I understand not repeating it.

Wow, that video was amazing! I enjoyed it ver much! Greetings from Austria!

yes

if you hit a creative block thinking you dont have enough views, keep going and push, this is amazing content man, your work will pay off i promise you

Hi i wonder if you could make a solar tracker (not with light sensor) but with mechanical adjustment which can adjust the sun movement a whole year.

i love your videos, Subscrived IMMEDIATELY. Never stop

Idk why, but this video felt like a let down I think it's either because the colors didn't feel right, or because it took so long to get to something about the drill i didn't already know Either way, still leaving that thumbs up and the comment to help the algorithm

> buy cordless drill > look inside > full of cords

👍

New subscriber Keep up the content please

Very nice

How do you make these? do you just buy the things you want to show and disassemble them?

Great video

Do you do all the video on this channel? Because it's very impressive!

Interesting

Impressing❤️❤️,, how did you do the animation.

Subscribed

Thanks

great

Nice

Best Video ever, nice job

Clear and concise, no nonsense, I greatly appreciate this work.

good description, but it shows a slightly older design, new designs have excentric self locking chuck collar that makes tying the chuck easier, and chucks are also shorter & simplier due to this.

I'm so glad I was introduced to your channel! Your videos are super easy to follow, the models are awesome, and I always come away more knowledgeable. Thanks for these!

Very good!

Such a simple tool to use with so many intricate systems packed into a compact package, just awesome!

Awesome animation! Now I wonder how ratchet screwdriver work

Great explanation. A lot of effort goes into making such animations

This video is so cool and I can understand everything

That was a really detailed video ..Keep it up buddy 🥰🥰

Can you make a similar video about an angle grinder?

10-15 yes ago, owning a set of drill and drivers. But thanks to China, we can own a couple of these with spares readily available

That variable speed switch...what is it exactly called? Where can I get one of those?

Detailed and informative video 👍

I didn't know a machine as simple as an cordless drill has such complex system inside. I use two 18 Volt cordless drills every day building cabinets and other furniture. The batterys I use all have a capacity of 5 amps. They can last up to 3 day of intense use before that run out of power. And I didn't know the cluth worked this way. One of my collegeas thinks that the ratcheting sound breaks the cordless drill. Thanks to you I can explain it doesn't break the cordless drill. It's a safety mechanism.

Great video! Clear explanation and high quality animation! Does anyone know what software was used to create this animation?

Excellent demonstration!

7:07 looks loke the zepplly family has something with it😂❤

Good explain this video Very useful

That’s great thank you

Great video, as usual!

Instant subscription!

Bro this is top work!

Can someone explain to me why it seems modern drills have a “braking “ mechanism that stops the rotation of the chuck when the trigger is released? Old drills would just slowly stop rotating. Does anyone know what I’m talking about?

which software are you using to create such animations? And how do you do dissolving animation at the beginning?

Thanks

which software did you use for this ?

This type of video is amazing! You keep this pace and quality up, and I'm sure you'll go far. Commenting at 71.3k subscribers. I'm betting you reach 500k subs in 6mo 🤞🏻💪🏻🙏🏻

Amps don't dictate the run-time. Amps are the amount of electrons flowing through the resistance, in this case, the drill. Volts or voltage is the force that sends the electrons/amps through the resistance. Example. The drill needs a certain amount of Amps to operate and a certain amount of Amps EVERY SECOND *the speed of the current* pushed by the volts. A small car engine needs 0.17 of fuel per hour (Amps), but the fuel ejector (volts) determines how fast the engine (drill) receives the fuel (Amps) in order to operate properly. In short, what determines the drill run time is the size of the parallel batteries in the pack. You want your car to run longer? get a bigger gas tank and the drill? add more parallel batteries Now, we can talk about the quality of gas and the quality of batteries...BECAUSE the compositing of the battery like zinc etc.. adds more life to the battery < and that's what you're talking about. But marketing won't tell you about that because it's not in their interest. They don't want to tell you the cheap materials in their product, because people will figure out why the batteries don't last. Just like the fuel quality matters.
