How do I drill a hole big enough for a chain link fence post in a cement driveway?

Question

I need to put a gate over my driveway-and I'll need to put at least 4-5 posts in it to hold the chain link fence & gate. How do I do that?

Answer 1

Hammer drill with a core bit. The hole will only be about 2-3 inches wide, not sure how you will remove the soil

Answer 2

You need a concrete hole saw. They can be had at any home improvement store and they attach to a drill. It will be slow going so prepare for that. Let the drill do the work, if you push to hard, you'll ruin the hole saw.

Answer 3

you might be better off to hire this out.  have a core driller give you a price on coring 6 inch holes in the concrete.  you can then dig post holes, set the post and concrete it in.

Answer 4

have a shop to weld attachment plate on the post, much cheaper and faster then other tools required to drill post size holes. Then use 5/16ths or 3/8inch anchors and bolts. Minimum of 4 per post.

Answer 5

Home depot rents a core drill I think it's about 45.00 a day.Get a bit about 2 in. bigger than your pipe. Then you can put cement back in hole after the pipe is set.

Answer 6

a big drill and a core bit...dont use a hammer drill with a core bit...
