Fastest Way to Cut Cast Iron Pipe 

he forgot his sandals

I didn't know that either... Ran into an issue with a cast iron pipe, decided easiest thing would be to cut it out.... Then said, oh crap... How do you cut through a cast iron pipe?? Lol.. Thanks for the education.

Make sure to use the right blades.

If is a heavy duty cast iron is a b..... to cut it.what he cut is a regular cast iron.

@@nickosmal what?

Glad you enjoyed the video. Thank you for your appreciation!

So glad to hear that the video helped you get our job done faster! Thank you.

Thank you, and you're welcome!

Glad to help! Thank you for the comment.

Glad to hear that you were able to get it done!

Thank you!

Thank you

Thank you for the kind words and the tip!

Awesome! Don't forget the carbide tipped blade. Cheers!

Thank you.

Great suggestion! I may do a video on that in the future. The purpose of this video was specifically to demonstrate the difference between cutting cast iron pipe with these two specific tools because more people are familiar with and/or have access to these two power tools. The question of which one of these two tools is best comes up often, so I chose to compare them in this video. The reciprocating saw is the clear winner. I felt that viewers would get the most out of seeing the head-to-head comparison so that they can clearly draw this conclusion for themselves. But I will take a moment to clear the air and clarify below. PUBLIC SERVICE ANNOUNCEMENT: Cut cast iron with a reciprocating saw, not with an angle grinder. The reciprocating saw cuts faster, easier, creates far less dust and sparks, and is easier to use in tight spaces (like in the dirt).

Hi! This is a carbide-tipped blade. Links to the blades used in this video are in the description box. If you are cutting 4-inch cast iron, go with at least a 9-inch blade. The blade used in this video is a 6-inch and as you can see its a little short and bumps the inside of the pipe at times. Thank you for watching.

I do need a vise.

I think the only way the sawzall would have been faster with a longer blade, is if you used different sections of the blade as you cut. I say this because the length of the blade stroke is determined by how you have the saw set. So if you have the saw set on the maximum stroke length (about 1-1/8 inches), the same amount of blade will make contact with the material you are cutting, regardless of the length of the blade itself. You can only manipulate this by sliding the blade forward or backward along the surface you are cutting, which will allow you to use a fresh section of the blade. Now you noticed that this blade does kick at several points when the end of the blade hits the inside of the pipe. A longer blade would have prevented this. And this did cost some time, so in that respect, we could save some time with a longer blade. Thank you for watching and for commenting. I recently did a video comparing the reciprocating saw in this video to the most powerful corded version of this saw by the same manufacturer. The results were surprising. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IWjp_RiSIEg.html

RENOS 4 PROS & JOES You have to cut like you’re cutting a tree with a chainsaw. Keep rocking the blade back and forth, then cut the bottom out so it won’t bind up.

@@5roundsrapid263 I follow what you are saying and that would work with a longer blade. I was explaining above that the blade used in this video is just barely long enough to make this cut because the length of the blade is almost the same as the diameter of the cast iron pipe. So the blade had to be positioned so that when it returned to the shortest point on its stroke, that the end of the blade didn't go inside the pipe and hit the inside wall of the pipe as it traveled back in the other direction.

That's a good idea.

Exactly! The reciprocating saw is the preferred and more practical choice. The grinder can get you by if there is absolutely no other option.

one hand on a grinder/uneven pressure is a good way to tempt a blade to shatter. google grinder injury photos.

Yes, you should be able to do it without a problem. Get a good blade and take your time. so that you can make sure that your cut is straight.

RENOS 4 PROS & JOES thanks for the tip. Keep the videos coming!

Thank you for the positive feedback! I wrote a blog post that includes links to both the 6" and 9" blade: www.renos4prosandjoes.com/cut-cast-iron-pipe/

The reciprocating saw is the way to go in most situations. It makes way less dust and is easier to control. I agree that the 6" blade I used here was a little short. Price was the determining factor on this one.

4 inch cast iron

Thats EXACTLY what this is.

My experience with cast iron has been demolishing and replacing sections of it. The reciprocating saw could work depending on how perfect your cuts need to be. If the cut ends have to be really precise, I would think the biggest hurdle would be keeping the blade and perfectly straight as you cut. But I'm sure there's a solution for that too. Thank you for the comment.

On the reciprocating saw what type of metal blade did you use to cut cast iron pipe

@@bobbymiller8563 it would probably be best with a diablo diamond tipped or a cast iron blade

@@bobbymiller8563 The link to the blade I used in this video is in the description box just below the video. I used the shorter blade in the video, , but I now prefer the longer 9" blade.
