not going to cost an inch and 3/4 all in
some six millimeter thick steel using an
old saw this is a relatively easy job to
do this time we're going to do it and
acquire this drill already demonstrated
how to do it in a pillow drill to do
this you're going to need a good set of
safety glasses and you're also going to
need some kind of lubricant we will be
using this drilling cutting and tapping
fluid that will keep the old soil cool
and it will also lubricate it when we
are pushing through this thickish piece
of steel when you're using your drill to
drill through metal you should always
start off with a center punch where you
want the drill to start that will stop
the drill bit from wondering when you
are starting the all another important
thing when drilling metal is to always
drill a pilot hole a pilot Hall is an
older is smaller than the actual all
that you intend drilling another rule of
thumb when you're using a cordless drill
is the larger the diameter of the older
you are drilling get the slower you need
to go so we need to go quite quickly now
because we're drilling a small diameter
all so I've put the drill into the
fastest gear I'm just going to put a bit
of lubricant on there a bit of coolant
just to protect the drill bit then I'm
just going to drill this all
obviously because of the size of the old
saw it is quite large in diameter so we
need to put the drill in the slower
speed and IIST
torque not only when you're using the
drill for drilling you would have it in
the drill position bolts on all sides
it's much more beneficial to use the
torque selector that means that if the
actual also gets jammed it will actually
slip on the torque rather than damaging
the Machine eye damaging you so it's
always a good idea when you're using all
souls to use the torque selector so
we're now just going to go through the
with the old saw and cut out this all in
this thick piece of steel
the difficulty is keeping the drill at a
law constant speed the ID you press on
is my attempting to actually squeeze the
trigger faster which goes too fast and
creates too much friction and too much
eat
you can see they've gone through there
now that is quite a thick piece of steel
to be using an also on especially in a
cordless drill so we cut that all out to
the relatively easily it's not a big
problem cutting holes like as long as
you take your time and usually drill on
a very slow speed and as I've already
said it's important that you use torque
control when you're drilling through
metal art using an awl saw it can
protect you from being injured and also
protect the machine from being damaged
