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 a drill driver
0:13
with 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
0:28
it's just a full lockup. So when the motor is connected to the chuck and it's just going to
0:34
spin and there's no slippage or anything like that. So for drilling and most applications
0:41
actually you have the drill set to the drilling position. If I were to move this over then what
0:46
I have is an adjustable depth feature. So basically the drill will deliver a certain
0:57
amount of torque and then no more. So it's delivering torque now. But you see I'm holding
1:04
it. The chuck isn't spinning. I've topped out on that particular setting. So this would be
1:12
for driving screws to a consistent depth all the time. So the lower the number, this number two
1:20
it's hardly delivering any torque at all. It's very easy for me to stop it from turning
1:26
And if I turn it all the way up, let's see if I can even stop it at all
1:32
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
1:50
here 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 going to
2:11
I'm going to get, now this is a brick, it's fairly soft, but I'm still not making very good progress
2:17
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
2:31
it's much much faster when it's drilling. See the difference? Let's do that again. Regular drilling mode
2:48
It's going in but not terribly fast and like I said this brick is soft. So if I was dealing with
2:54
concrete block or poured concrete the difference between hammer drilling and regular drilling would
2:59
be even more stark. So you see there's quite a difference there. You'll probably be doing some drilling into
3:17
masonry when you're finishing your basement so that hammer drilling capability is pretty important
3:22
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 six
3:45
months of storage you're going to get your tool, your battery's flat. Lithium-ion stores more
3:50
energy in a smaller space. It doesn't self-discharge at all really or very very little and
3:58
it's a smart battery too. So for instance I press this button. See I've got three quarters of a tank
4:04
so to speak of energy in this battery and they can operate when it's cold without damage
4:13
If you've had bad experiences with cordless tools in the past, the new world of lithium-ion tools
4:20
which is across the board across all brands is really going to surprise and impress you and
4:26
yeah it's just the way to go. One other thing here, just this. Almost all drills have this
4:35
It's like a low gear and high gear setting so for drilling in certainly in metal
4:42
and sometimes in masonry you'd want a slower speed. So that's full speed on the low gear setting so you're going to have more power slower speed
4:55
Faster speed, lower power. Now this is a professional grade tool and a drill like this
5:04
with you know some kind of a battery and a charger might be two or three hundred dollars. You can get
5:10
a bargain basement consumer grade drill for maybe a hundred but in my experience the you
5:20
pay a little bit more and you get a whole lot more tool when you get into the professional grade and
5:26
you need to think of yourself as something of a professional when you're when you're finishing
5:31
a basement you're taking on some serious work and you don't want to short change yourself
5:35
with substandard tools. So there you go cordless drill driver hammer drill
