Welcome back to Albany County Fasteners - Fasteners 101
I'm Bob and today going to show you and demonstrate how to properly drill a hole in a piece of structural steel.
So let's get started.
I have a push punch here. This is a spring actuated punch. I'm going to align
the punch with the steel where I want to drill my hole and all you do with this is push it and then it springs and
pushes a hole. I'm going to do this three
times without removing it. Just to make
sure I have a good starting point you
can see there that I have a very good
starting point for the drill. I have two
drill bits. This is one that is used
which has a 135-degree tip on it. These
are the best drill bits for drilling steel.
They are the quickest in drilling through steel and they are the most efficient drill bit.
So I'm going to start with this drill bit I have a new one.
I just want to show you how long it
takes to drill a hole with a used drill bit
and then show you how fast a newer drill bit will drill that same hole.
The other thing that you must
have along with your drill bit that
you're going to use and of course, it
must be for drilling of steel,
is this lubricant here, which is
basically made for lubricating the drill bit.
All you have to do is just put on
just a little dab, on there,
put it into your set hole that I just set. See? It won't even move around.
Now when you're drilling you don't want to drill at very high speeds.
if you drill at high speeds it will not
drill effectively; it will drill a lot
slower. So I have found by varying the
speed up and down I get a much better result
of quicker, faster drilling the hole out and I'll show you that now.
So I'll start off slow and then you'll start to see, you just vary the drill speed up and down fast and slow,
never go over 2200 rpm. Which, I don't have my drill set to that.
We're probably doing anywhere from 600 rpm to about 1200 and you want to keep steady
pressure on your drill. Now I'm going to
change out my drill bit and I'm going to
slide in a new a new bit. That bit has
been used probably a couple of dozen
times, I would say. Tighten it (the new drill bit) in place. I'm going to punch a hole again like I
showed you. These are one of the best
punches you can buy. You don't
have to use a hammer you know it makes a
nice little mark for starting and you
just push on it, spring actuated. I'm
going to throw a little goop on here;
lubricant and this is a new bit so this
will show you how much faster a new bit
it's going to flow through this vs., Okay, I got the hole, a bit that's been used about
two dozen times. So you can see by
using a new bit not trying to keep using
that old bit, it's gonna be more
efficient for you to drill holes in. If
you only have one hole the drill then I
guess you know you can keep using it an
old bit but obviously a brand new bit
you'll get a lot faster more efficient
cutting. Thanks for watching.
It's Cool Creations winner time.

Megan created a beautiful table and
benches using our hot dip galvanized
carriage bolts, washers and nuts.
The combination of metal and wood is
rustic and beautiful these pieces look
like they will withstand the test of
time thanks again for sharing your
creation Megan and congratulations on
