on today's episode we're gonna cut
concrete with a circular saw now this is
just an ordinary Sidewinder style
circular saw if you have a worm drive
saw that's really gonna be a better
option for this because you've kind of
got a little bit more isolation between
a motor and in my case the water that
will be touching the floor but we'll
make sure to take lots of safety
precautions just to try to you know make
sure nobody gets shocked here the first
safety precaution we're gonna do is
we're gonna make sure we plug this onto
a GFI outlet so I'm running this to my
kitchen where I've got a GFI that if
something were to short out because of
the water it'll pop and stop rather than
shock you you know the the other thing
I'm gonna do is they recommend you wear
gloves of course you never want to wear
anything loose with a saw like this but
I will be wearing some rubber gloves
just to provide an extra layer of
isolation I'm gonna of course wear
hearing protection cuz it's gonna get
really loud and I'm gonna wear an actual
pretty nice respirator because you
really don't want to be breathing in
concrete dust at all I will this this
blade I'm using is a Bosch it's a DB 7
for 1c and it's a segmented style blade
and you can use these blades wet or dry
what it's obviously gonna obviously
going to last a lot longer dry is gonna
create a lot more dust so it's kind of
your choice as to what you want to do
there but to keep it wet what I'm going
to do is I've got a hose here and I'm
just gonna trickle water the more
normally you'd say the more water the
better but because I'm using a
sidewinder style so I'm probably gonna
go a little bit lighter on the water
than you would if you have a saw that's
more recommended for wet type cuts so
one thing we're also gonna do is I've
set the depth to probably three-quarters
of an inch
she really shouldn't they recommend
cutting only the depth of each
diamond tooth just to prolong the blade
so don't go ahead and just take a huge
deep cut into the concrete so I'll
probably make I don't know four passes
in order to cut through this but we'll
see how this blade performs here and
give it a try
so that created a little bit more dust
than I expected I went ahead and I
turned up the water here and that'll
hopefully kind of keep it a little bit
more wet so it doesn't make quite as
much dust
[Music]
so one little trick I've already learned
is make sure you push the water in from
kind of angle it at the back of the saw
if you try to push it towards from the
front of the saw the the saw kind of
blows the water away which again just
creates a tremendous amount of dust
which just kind of stinks to work with
so we'll go ahead and we'll do that
again
so I would say this blade actually
worked really good you could tell it was
kind of pushing back the amount of water
that it took to keep this thing
relatively dust free was a lot more than
I thought I really had this thing
flowing pretty good because otherwise it
would just poof dust everywhere but it
seemed to cut great there's really no
snow change in performance from the
beginning to the end here so I would bet
you could really make quite a few cuts
with a saw or with a diamond type blade
like this now everything I've used in
this video I'll make sure to put a link
so you can buy if you want like a
respirator if you don't have a GFI
nearby you could buy an inline GFI for
your for your extension cords and stuff
like that but hopefully this will help
you if you want to do something like
this break a spot out on your floor
without breaking more than you really
need to it's kind of a nice little tool
to have in your bag thanks for watching
