I am planning to renovate my kitchen in a 200 year old home. The range im looking at requires a 10" round hole.

I likely will not drill the hole myself, just wondering what this would involve, and what type of cost would be associated with this.

Thanks.

That is a really big hole but this will show you some of the detail and things can go wrong.

You provided so little information no one can help you. How thick is the wall?
You could always get a 1/4" roto hammer bit long enough to reach and drill 27.5 holes around the circle and use a chisel.

Cost is free, we do not know where you are.

Hint if this is a stone wall best bite the bullet and core drill the hole.

The wall is 18" thick. The stones vary in size from a few inches to 1-2'. The walls are skim coated with plaster on inside and outside.

If you can find someone with a 10" core bit, it will be extremely expensive. It's a huge drill bit machine that bolts to the wall.

You're going to need a mason. SW Dweller's idea is a good option. Drilling a series of holes in a circle will weaken the stone enough to be removed easier.

The other option is remove a larger section of the stone then lay the stone back in around the pipe.

This is a pretty tedious job, and it will get messy.

There's no other option for the location of the pipe?

That big hole indicates a high volume exhaust fan, not mentioned. Anything 400 cfm or larger includes the caution of backdrafting other appliances. We don’t know but you should investigate.

The current kitchen range has a downdraft into the basement which pipes the air out through a window well. I'm looking to get rid of that. The range hood I'm looking at is 1200 CFM. Unfortunately the walls around the kitchen are stone. I have a draft of my future kitchen floor plan below. The area to the right was an addition built 70 years ago that was framed up against the stone walls. There aren't many options.

A lot of rental places have large core bits with the bolt down stand drill stand. Last one I rented that size think it was like $150 -200. bit and drill.

I'd look for a different range before paying for someone to cut a hole through an 18" wall.

 

[Marq1]

1200 CFM.

For someone who has never had any kind of vented kitchen fan, and never felt the need for one, that sure seems crazy air volume.

 

[Bud9051]

Well 1200 cfm certainly is larger than 400. Make sure your local authority isn’t going to require a dedicated make-up air system, they are expensive. Local authorities rule.
What do you have for furnace and water heater ?

I have put holes in stone cellar walls by chipping at the mortar and removing rocks. A hammer and mason’s chisel works. Generally the old mortar is not very hard to chip out. The resulting hole is about twice as big inside as it is outside by the time I get through it. Then I install a sleeve for whatever it is that I want to put through the wall. I rebuild the area around the sleeve with mortar and stones. It sucks and there are other things I would rather do, but it is doable.

This conversation has put things into perspective for me. I found other 48" hoods that operate at 400 CFM. I think 1200 was overkill, although the trim would have matched the range, it isn't critical.

The 400 CFM hood only needs a 6" hole. Is this something that can be done with a common core drill bit in one pass?

Yes...6" is much easier and cheaper to do than 10".
Any idea how hard your stone is? If soft, a cheaper bit would work fine.

Does it have to go out through the wall? You can't go up through the roof?

3 story federal style home with stone wall behind the range that runs to the roof. There is no way to hide the vent within the wall. As for the hardness, the mortar is soft but the rock is sandstone which is on the harder side. I've drilled some small holes for electrical boxes, it eats through my masonry bits.

It might even be fieldstone instead of sandstone, i really cant tell but there are lots of browns, reds and blues visible in the foundation. They used the rocks the farmers found in the soil to build the houses in this era.

Your house construction is similar to mine. The stone on mine is Chert which is similar to flint. As it lime mortar, I usually remove the stones to get a pipe through the walls and then rebuild back around the pipe.

Even with a 6"hole a bolt down stand should be used.
