How to Cut ICF Foam for Electrical Wire and Plumbing Pipe

Here are a few ideas for cutting channels in ICF foam blocks in order to run electrical wire and plumbing pipe. The method I used most, and recommend, is the Angle Grinder with a Chainsaw Disc.
Knife & Reciprocating Saw
amzn.to/3peKOiF
amzn.to/38lclYS
Electric Chainsaw and wheel
amzn.to/3mDnWaN
amzn.to/2KBOKLf
Angle Grinder with Chainsaw Disc (this is the cheapest and best option)

Cool, valuable information

Actually the router is an interesting idea. I'd seen the hotwire, chainsaw, and handsaw before. Besides a few wired routers for wood working, I have a Kobalt 24V battery operated portable router that would work great I think. My electrician wants to run conduit for all in-ICF wire so it should be easy to use with a wide simple bit

Can I just use an oscillating saw? Or has the depth with a larger blade?

Nice video. 1" depth doesn't meet electrical code though. 1 1/4" plus the width of the wire is needed. Closer to 2" is what you need..

Yes ,The Red saw is dangerous
