can I cut a new access hole in brick & clay chimney?

I have a 2 story house with a brick chimney that used to be used for the furnace in the basement. The house now uses a gas furnace so the chimney is no longer used.

It appears to be in good shape, it has a clay tile liner ( I think that is the right terminology) and it is perfectly placed to use for a stove on the first floor.

The issue is that there is no access hole to the chimney on that floor.

Is it doable? Easy? Hard?

All I can say is cutting a hole through masonry is relatively easy with the right tools. You can use anything from a simple hammer drill and carbide bit to a diamond blade for a grinder or circular saw, hole saw/core bit, or chainsaw with a diamond chain. (yes, they really make them). The bad side is it will be messy/dusty, and LOUD.

Unfortunately, I can not tell you if it is a good idea. For that, you may want to consult a fireplace pro.
