So in this video I want to give you a tour of a full featured cordless drill so that if you have
0:06
to buy or borrow one you're going to get the right kind. So this would be called a drill driver with
0:14
hammer drilling capabilities. And so I guess I'll start here with this adjustable collar here
0:23
So that's a picture of a little drill bit and when I have the drill set into this position it's just a full
0:29
lockup. So when the motor is connected to the chuck and it's just going to spin and there's
0:36
no slippage or anything like that. So for drilling and most applications actually you have the drill
0:42
set to the drilling position. If I were to move this over then what I have is an adjustable depth
0:51
feature. So basically the drill will deliver a certain amount of torque and then no more
1:00
So it's delivering torque now. But you see I'm holding it. The chuck isn't spinning
1:07
I've topped out on that particular setting. So this would be for driving screws to a consistent
1:14
depth all the time. So the lower the number, this number two, it's hardly delivering any torque at all
1:22
It's very easy for me to stop it from turning. And if I turn it all the way up, let's see if I can
1:29
even stop it at all. I can but I have to hold it hard. So that's the... when they talk about a drill driver
1:38
that's what they mean. They mean a drill that can drill in full lockup mode and then a drill that
1:44
has this depth clutch feature. That's the driver part. Now in this case there's a little hammer here
1:52
and when I turn it there I have full lockup. So it's not going to slip no matter what. But in
1:58
addition to rotating there's a kind of a hammer motion and that's very useful when you're drilling
2:04
masonry. Because if I just have it in the regular position here and I drill. I mean I'm gonna
2:11
I'm gonna get... now this is a brick. It's fairly soft but I'm still not making very good progress
2:19
I'll spend all day doing that hole. But if I put it in hammer mode you're going to hear the drill
2:26
sounds different because it does this this hammering action as well as rotation and it's
2:31
much much faster when it's drilling. See the difference? Let's do that again. Regular drilling mode
2:48
I mean it's going in but not terribly fast and like I said this brick is soft
2:53
So if I was dealing with concrete block or poured concrete the difference between hammer drilling and regular drilling would be even more stark
3:02
So you see there's quite a difference there. You'll probably be doing some drilling into masonry
3:18
when you're finishing your basement. So that hammer drilling capability is pretty important. Just a few other things. Nowadays cordless power tools exclusively have lithium-ion batteries
3:31
Previous generations of batteries were nickel cadmium mostly and they're not great batteries
3:40
They don't have a long service life. They discharge slowly on the shelf. So after
3:44
six months of storage you're going to get your tool your battery's flat. Lithium-ion stores more energy in a smaller space. It doesn't self-discharge at all really
3:55
Very very little. And it's a smart battery too. So for instance I press this button
4:03
See I've got three quarters of a tank so to speak of energy in this battery
4:07
And they can operate when it's cold without damage. If you've had bad experiences with cordless
4:15
tools in the past, the new world of lithium-ion tools which is across the board across all brands
4:22
is really going to surprise and impress you. And yeah it's just the way to go
4:29
One other thing here. Just this. Almost all drills have this. It's like a low gear
4:37
and high gear setting. So for drilling in certainly in metal and sometimes in masonry
4:43
you'd want a slower speed. So that's full speed on the low gear setting. So you're going to have
4:51
more power slower speed. Faster speed lower power. Now this is a professional grade tool
5:02
and a drill like this with you know some kind of a battery and a charger might be two or three
5:08
hundred dollars. You can get a bargain basement consumer grade drill for maybe a hundred. But
5:16
in my experience the you pay a little bit more and you get a whole lot more tool when you get
5:22
into the professional grade. And you need to think of yourself as something of a professional
5:27
when you're when you're finishing a basement you're taking on some serious work
5:32
and you don't want to short change yourself with substandard tools. So there you go
