CONCRETE FOOTINGS – cutting through?
The plumber has laid his drain routes – through or along four 50 yr. old footings. Yes, the concrete has cured very well. Amazing stuff, really. One run he might want to change. The rest go with the job.
I think we sent the 90# jack hammer back an hour early last week. The Bosch Brute just bounces along on this stuff. Drilled a bunch of holes, hoping to connect the dots and chip out chunks. We chip out dust.
Which leaves me very open to suggestions ranging from C4 to ______.

Down there in SoCal? Call a concrete cutting / core drilling outfit. They cut that stuff like butter. Any tool you might have for that is a silly toy next to theirs.

Are you calling the Bosch Brute a silly toy?
Next to that 90# hammer and air compressor, it is.
But, the core people want $$$. But of course. That hole saw runs $1500.The ToolBear

The connect-the-dots method of getting thru a wall for a pipe is like murder with a blunt instrument. Yes, the core drilling guy wants $250 just to show up, or more, but he can drill you a perfectly clean hole right where you want it. You won't have to spend any time sealing up the pipe penetration and you can spend your time doing something that you're set up for instead. I have hired core drillers to drill holes, saw walls and floors, grind floors, etc., and would never go back.
If it's your own house, and time is NOT money, then go after it with the Bosch, but you'll be hatin' it.
Shop the cutting / coring. I've found very big differences between guys. If they get the opinion you're a HO doing it hisself, the price is doubled.
Are you talking about a footing or a foundation? it makes a major difference.
Footing is part of the foundation. It should not be drilled unless and engineer OK's it. We drill or block-out thru the stemwall near the bottom, just above the footing.
Thats what I was trying to find out, where was the original post trying to drill into.
There should really be no reason to run thru a footing. Drop another six inches and you are under it. Easy digging

We get into elevation issues when the tank or lateral outside is at a specific elevation. Right now I am looking at hammering a hole in rock to get the tank low enough, and it will be necessary to go thru the stemwall with the drain out.
I feel for ya!but there is some crete in my way;)

It's always either crete, rock, or some other. Take yer pick!

I shall suggest same to the plumber. I think he was trying to hold at -12", where the old stuff ran. There was an issue of having enough fall if we had to run a drain all the way to the back of the addition for a Tiki Bar.
I am not sure what a Tiki Bar looks like. Torches? Sweaty, muscular natives in loin cloths swilling drinks with umbrellas in them?
He has two gentlemen of Latino extraction digging across the yard, across the house. Nice, neat, square-sided, smooth-bottom trenches. Of course, their efforts caused the clouds to gather, then dump with some vigor. They spent much of Friday inside, digging and hammering.The ToolBear

toolbear, I have run into situations where due to the fall needed between two fixed points I had to go through the footing. What we did was dig out under the footing, use a demo saw to cut the footing as much as possible , then drill or hammer the rest. I have had this done both by laborers and core drilling companies.
Always we had to then go back and repour a new footing beneath the old one and tie the new one to the old footing.
