The BEST Way to Cut Cast Iron Pipe?

Sharing buttons:

hi guys it's me again and today i'm

going to be demonstrating

how to cut cast iron sewer pipe you can

use either a grinder or reciprocating


i prefer a reciprocating saw there are

also snap cutters but they're really


suitable for new cast iron like this and


used rusty pipe like that

so you'll need to use a reciprocating

saw of course

you need blades i like these diamond

blades they also make carbide ones like


it's really up to your own preference i

would suggest buying both

and just seeing what you like better you

will also need a reciprocating saw

you need a high quality

professional grade saw and a full-size

reciprocating saw don't try to use on

those mini compact ones

it won't do the job and don't try to use

a diy grade saw like the ryobi ones

they're not meant for cutting heavy

metal like this pipe

so now let's get started this is a brand

new blade

i have decided to try lenox brand

instead of my usual milwaukee

and i'm using my m18 fuel sawzall

which is a really good reciprocating saw

especially if you get it on sale which i


so now you just line up the pipe

and line up the blade of the pipe and

start cutting


so that took about a minute to cut three

inch service weight cast iron pipe

and the cut is pretty smooth which means

you can attach a furnco or no hub

fitting to transition to another pipe


now let's try out using an angle grinder

just like with the reciprocating saw

you'll need a heavy duty professional

grade model

a diy angle grinder will not be up to

the task

i like using diamond metal cutting


here are two different brands not to be

confused of diamond masonry blades of

course but

i just feel that these blades are safer

because there's no risk of

flying debris if it breaks and

it fits any standard angle grinder i'm

using my makita paddle switch grinder


now the problem with using an angle

grinder is it'll throw a lot of sparks

and you have to have full access to the


but let's get started cutting

obviously that took a lot longer and it

throws a lot more sparks and debris

and also the cut is not as clean but you

should be able to get a no no-hub

coupling or a furnco fitting right on

there with no problems

so after trying both these methods i

still recommend

the reciprocating saw for diamond blade

for cast iron

with this blade once one side gets too

dull you can flip it around and use the


just kind of a cool feature so yeah i'll

have a link to the tools and

supplies i recommend in the description

so anyways i hope you guys enjoyed this
