View Full Version : Making a 4" hole through brick.
10-29-2006, 12:06 PM
What's the best way to make a 4 inch hole through brick to install a 3 inch laundry vent. Is a corded hammer drill powerful enough if a 4" carbide or diamond hole saw is used? If so, would you use the hammer drill mode or the regular drill mode?

What is the size of the brick?
I would practice on a loose brick b/4 I would do the brick that is already in the wall. Practice with the non-hammer mode 1st.

I'd rent a drill and coring bit for this. (I say this because you are loosely describing a holesaw and sounds like you don't have one yet). A coring bit is typically segmented for drilling through thick brick and block like this.
But only drill a hole 1/8" larger than what is necessary. You said you have a 3" vent, but are you sure it isn't a 4" vent? I ask because every vent coming off a dryer that I've seen is a 4" vent. :)

i used a sds plus hammer drill - gets through anything with a chisel attachment.

Yep, it sure will. Gotta be real careful when you chisel, as it may break some of the bricks loose.
Hi Karl, welcome to the forum. Hey, it sounds like you are a professional. Take a minute and stop by the "Pros Hangout" forum and introduce yourself. We sure like to know a bit about the pros giving us a hand answering questions. :)

I was hoping not to have to rent any equipment to do this. Could I just cut a 4" square with a skil saw, rotozip, or angle grinder using a masonry blade?
BTW, what's an SDS?
