Cutting Concrete with a Circular Saw

Sharing buttons:

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


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


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
