hello I just want to just spend a little
bit of time talking about drilling holes
into steel and something I've just kind
of come up with over the last few years
is using these annular cutters sometimes
they're called sheet metal hole cutters
it's just a set that you buy with a
different screw on cutter style this one
here goes from quarter inch to 3/4 inch
on standard sizes but you can get them
pretty big all the way up to an inch or
what have you but you know before I knew
about these I used to take a long time
to drill a hole let's say I wanted to
drill a 3/4 inch hole into some steel
you know I'd start with say a 3/16 built
bit work my way up from there just keep
drilling drilling drilling till you get
up to some of these bigger bets and if
anyone if you have ever used any of
these bits you know that they're very
tough going through thick steel sic
quarter-inch steel lots of chatter and
lots of damage to the bits themselves so
I highly recommend getting a set of
these basically all you do is you're
going to Center punch on to your
material and then you can see here it's
got a spring-loaded guide you can use
this on the drill press or I do it do it
by hand as well in a drill I'll just
show you a couple examples of just
drilling through some steel with these
but basically it's a one shot hole and
also its salt it's a you know centers
itself perfectly sometimes when you
start drilling with a smaller bit and
work your way up the hole will work its
way over one way or the other depending
on the way the bits bytes so you want to
drill a precise 3/4 inch hole into
something for you know say a pivot point
on something these things are awesome
they save so much time drilling holes is
always much of the most annoying things
I do but now that I have these just
amazing just search for a sheet metal
hole cutter there's all kinds of sets by
all the coal companies out set like this
cost about a hundred bucks but it is
well worth it so I'll just show you a
couple holes I've drilled with them but
anyways all my projects I use these on
they are awesome
yeah so that was a three-quarter inch
hole with the single pass and you see
it's a nice cut nice hole another thing
you can do here actually is I could
drill another hole across the center
here if I wanted to make a slot for say
an adjustment on a bracket or something
so I'll show you that
so here here's three holes in a row and
I would just grind that out normally
blow on it to make a slot pretty handy
tool
