In this video I want to explain to you some of the tools and bits that you can use for drilling as you're making a deck project
0:08
Drilling in wood and drilling in masonry. So the least expensive kind of bit that you need to drill holes in wood, large holes in wood, would be something called a spade bit
0:22
I mean this is one here. Every hardware store carries these and they seem simple but they do a great job when they're sharp
0:32
It's fairly easy to resharpen them as I've explained in another video
0:36
But this is the kind of bit that you'd use to drill holes for carriage bolts and leg bolts and things like that
0:44
So larger holes, larger than what a regular drill bit could drill
0:50
Now this is kind of like a regular bit in that it's a twist bit
0:57
It's a half an inch in diameter but it's fairly long. They call this an installer's bit because it's got a little hole in it here
1:06
So if you were drilling through a wall and you wanted to pull a wire through you could attach a lead wire onto this after you've drilled it through
1:15
and pull it through and then attach that to your cable and pull that through
1:19
That's not for deck work of course but that's why this is called an installer's bit
1:24
I like these because they're fairly fast and they're longer than usual as well
1:30
Now when I have to drill a hole that's very long, maybe through a couple of 6x6s or even larger than that
1:39
then I recommend this auger bit. This works on a bit of a different principle
1:44
It's slower than some of these other bits but it powers itself through
1:50
So if you look here on the tip it's got an angled threaded screw type end
1:56
That tip along with the shape of the bit causes it to be self-feeding essentially
2:02
You just have to put it on the wood and turn the drill on and it'll pull itself through
2:06
It'll also auger the shavings out very well too. This is the ideal kind of bit for big holes that are also deep
2:16
Now this final kind of bit is what you'd use for drilling in masonry
2:22
So concrete, block, brick, stone. It's a masonry bit and it's not very sharp
2:30
These bits need to be sharp if they're going to cut through wood properly but not so the masonry bit
2:37
The thing about a masonry bit is that the cutting edge needs to be extremely tough and abrasion resistant
2:43
because it's rubbing up against highly abrasive material. So that's what you see here
2:48
A bit like this would not do a great job through wood. You can blast through an inch and a half of say ledger board on your way through a brick wall
2:57
That would be on your way into a masonry wall. That would be fine. But for regular drilling in wood you need to use something else
3:04
But this is what a masonry bit looks like. It spins and the kinds of drills that you'd use this in also have a pounding action
3:13
So many times a second it's going back and forth a little bit and it's spinning
3:19
And that's what lets a bit like this burrow its way through masonry quite quickly
3:25
You can use bits like this in a regular handheld hammer drill which I'm going to show you in a second
3:34
Equivalent bits are available for use in larger rotary hammers. And I've explained all about that in other videos as well
3:42
But this is for a handheld drill and that's what I want to show you right now
3:46
So this is the kind of cordless drill that makes sense for most of the hole boarding operations you'll need to do when you're building a deck
3:56
There's some features here I want to show you about in case you want to buy or borrow the right kind
4:01
So this is called a cordless drill driver. And the reason... a cordless hammer drill driver actually
4:11
And that's because it has three different functions. So it spins just like a regular drill
4:17
And when I want to drill in masonry for instance, this is just a regular spinning setting here
4:26
That's a little picture of a drill bit. And so it just spins
4:32
Full lock up and full power of the drill is constantly transmitted through to the chuck
4:39
Now if I turn it here to the hammer position, it's still going to spin
4:44
But if I was drilling masonry and pressing against the bit, you'd hear a kind of a buzzing sound
4:51
You should be able to hear it even now. See, it didn't do that before
4:57
In drilling mode, just spinning. Now if I get it to hammer mode, and that's that pounding action I was telling you about
5:05
So it's turning and it's pounding and that's what lets it blast through masonry very well
5:10
Now there's an intermediate position here too. And that's the driving position, so driving screws in other words
5:17
And when it's in that position, the drill delivers more or less torque depending on the setting of this outer collar here
5:25
None of this is unique to Milwaukee. Most drill driver hammer drills are designed the same way
5:31
So if I have it set down low... See, the chuck isn't spinning here. It wants to spin
5:39
But then when I apply resistance, the torque is limited. So the idea being that if you set this right, you can drive a bunch of screws in to a consistent depth automatically
5:53
Because it'll just drive with a certain torque and then the clutch will slip and then that's that
5:59
In practice, as I've explained before, an impact driver is a much better tool for driving screws
6:05
But it's not essential. This drill will drive screws passively well. It's an 18 volt
6:14
18 volt, 20 volt, doesn't really matter. They're all pretty much the same as far as power is concerned
6:20
And this has a 2-speed transmission, so to speak. So this is in position 1
6:27
So, relative low speed and more torque. This is the kind of setting that I would use if I was using an auger bit, for instance
6:38
Or the masonry bit. Now, if I put it into position 2, much faster speed and lower torque
6:47
And this number 2 position is what I would use with the spade bits
6:51
Because they do need a faster rotation in order to drill through wood
6:56
So, that's kind of your basic crash course on drilling for deck construction and the kind of tool that makes sense for that
