How To Drill Concrete Hole Straight (No Chipping)!!!!

After a lot of discussion from my original video about drilling concrete we decided to make another one. We have came up with a better way of doing it now.

[@TheFluffyKitty]

Thanks a lot my dude. I needed to bore a hole to install my AC and now it looks clean ☺️

[@OnTVaustralia]

This is gold! Thanks so much.
I have to drill a 3.5" core hole through double brick and i have already drilled my 10mm pilot hole.
Was going to do similiar by cutting a hole in timber to use as a template, but your method makes more sense, apart from the fact i already have the 10mm pilot hole

[@campbellbuilt]

I’ve done both styles and they both work great but the pilot bit guarantees exact placement and tear out on the other side.

I was using this drill for mixing mud and stud drills. Thanks for enlightening me to this new application.

[@campbellbuilt]

This thing is awesome. I’m surprised that it’s as affordable as it is for what your getting.

You’re humorous at the same time informative, A Nobel prize 😀😀 ?

[@muhammad8970]

Thanks for the demonstration 👍🏿

[@campbellbuilt]

Your welcome

[@ronaldnaeyaert3653]

The plug and tapcon is great idea. Thanks

[@campbellbuilt]

[@mackshinoda9969]

Superb hand work 👍 good

[@campbellbuilt]

Thank You….😀

[@zebra5star925]

Brilliant!👍

[@campbellbuilt]

Thank You

[@mderking]

There are also center bits you can get, that made of 2 crossbars that fit in your drill, with a center bit on it. For the same purpose, but no wood needed ;-)

[@SleazyRay1974]

great idea!

[@campbellbuilt]

Thank You

[@user-ih2dg7vr5u]

Great Technique .......

[@campbellbuilt]

Thanks!

[@CxStark]

That's a beautiful hole brother

[@campbellbuilt]

These little things in life sure can make you happy. Some one might say it’s “Just a hole” but it’s a hole in stone or concrete 😀

[@mariosilva3530]

Hi.
Where did you get the bits...?
Thanks!

[@Daniel-hk6kb]

Good idea！

[@EdTravelingEast]

Nice work

[@campbellbuilt]

Appreciate it

[@Liquidmc516]

Who makes the dry core bits you use in your videos

[@rmcf3972]

What specific dewalt tool you used? I want to make a hole out of a 7 inch thick concrete for cctv wiring.

[@zataraarataz8545]

Thank you, this will help ..

[@campbellbuilt]

You're welcome!

[@Angel_268]

Great video is this the same method to use on a 7” thick wall?

[@ltalbert81]

Really nice idea! I would use a larger sds bit (3/16 x 12), It will break the other side, but just a little bit, then the plywood and the tapcon. Thanks!, Sorry for my english.

[@campbellbuilt]

Appreciate the comment.

[@user-ty6wj8bq2m]

What's the brand of core bit that you use? I see a LOT of core bits advertised, but a LOT of them say "do not use on concrete". I have to bore a 2.5" hole in concrete to install a fence door post support. Can these bits be used on concrete? What brand are they, and where did you get them? I want to bore a 2.5" hole, go down about 2 feet past the edge of the concrete wall footer, install a 2.5" diameter post shell that goes from the surface down into the ground, and then install a 2" fence post that can rotate, while carrying the fence gate, into the sleeve pipe I installed through the concrete.

[@ToplessTattoo]

Your a genious

[@mattsouza4395]

Winners!

[@campbellbuilt]

I’ll take it

How to make a 4inch hole in a exsisting 3 inch hole in wall brick wall, can you double stack the hole saws?

[@campbellbuilt]

No, there’s a couple solutions.
1st would require two wood hole saws. Cut a plug out of a 2x6 using both a 3” and 4” wood hole saw bits. Attach both wood plugs together and use that to temporarily get your 4” started.
2nd is us the method in my other video th-cam.com/video/EJhBEKcSbj0/w-d-xo.html

[@user-cq1go7io2b]

Its called a Core Drill Block.

[@keeptrying7640]

Hi I'm looking for a bit set like that 4 inch and 2incn one you have Tha long one

[@campbellbuilt]

eBay or Amazon

[@joleneguerrero4794]

Can we use the core bit on a regular drill to do a hole in concrete? Or is it necessary to use a hammer drill? I need to make a hole for my kitchen sink drain 😩 Newbie with tools 🤷‍♀️

[@campbellbuilt]

Regular drill is just fine.

[@joleneguerrero4794]

@@campbellbuilt thank u for responding so fast 😊 happy holidays

[@IWBVS]

Will it cut through asphalt?

[@campbellbuilt]

Oh yahhh. With ease.

[@rickbraden4272]

8m new at this so I may be wrong but I know you can get break out with carbide core bit in hammer mode. But why would you get break out with a diamond core bit that's not hammering? Thanks.

[@campbellbuilt]

Typically both sides of the block wall or concrete will be visible to the eye. I want a super clean hole for that reason since there’s no good way to repair damage after the fact. Yes your right about not using hammer mode and being better for break out but concrete is a funny thing. Block is especially susceptible to break out regardless of how your drilling. Good question.

[@buckshot5896]

If did this on my job I would fire him. I’m an electrical contractor, everyone has proper tools on the truck or at shop. Plus it took way too long to lay out, I could have drilled 20 holes. They make dry core and wet bits that makes it simple

[@campbellbuilt]

Okay 🤣🤣🤣

[@jimgarcia5165]

He did it the hard way there is an easier way to do this

[@campbellbuilt]

Okay, now show us 😀

[@divinicus]

please don't waste the viewer's time with talking about your yard when they're here about coring

[@campbellbuilt]

Please leave

[@Fishpalms]

I bet your yard hates you! 🤣

[@Funky4me21]

Guess he don't like his eyesight.. most important thing to do is protect that!
