.45 ACP twice?
j/k Most hardware stores carry a full line of masonry bits for your drill. I wouldn't drill smaller holes in a circle and punch it through. Cinder blocks don't always break apart uniformally. |

Lots of little holes drilled into a larger circle slowly with a hammer drill, then tap out the center like with any other masonry. CMU's like to shatter, be careful. |

do it the ARFCOM WAY! acquire a weapon in the 23-25mm range and punch a hole in that wall...and everything behind it for a city block.

Buy a 1" masonry bit.
Go slow, don't overheat the drill. Your drill will probably go through cinderblock without breaking a sweat, 1" might be pushing it in concrete, but cinder block isn't going to be a problem. |

What would you do if a block wall separated you from ARFCOM and wireless is a no-go option?
Even though my drill is rated for 3/4" bits? This sounds to be the fastest solution, is the 3/4" rating for concrete and harder surfaces or something? |

Cost of the bit VS your time.
Is the price of the 1" bit so much, to make drilling alot of 1/4" holes worth the time? Your drill will work great with a 1" bit on block. |

I have done this as well one shot...pow!....hole But if he isn't careful he wont succeed the first time and get silly with repeated blows and weaken the block and it will crumble. |

If its just one hole then use your 1/4 bit and then tap the center out. If its lots of 1" holes then invest in a 1" bit with a 1/2" shank.

seriously, use a hammer to make the hole. its easy, and no extension cords/drills required. tap where you want the hole, keep going, tapping a little harder each time. use a hammer with a 1'' diameter head for 1'' hole.

If it's just a hole to pull wires, I would just knock it out with a hammer as well.

I drilled a hole through my foundation to run an external outlet. I used a 2 ft drill bit on an impact drill. I think that's what it was called. I have a contractor friend that happened to have one and he said that was all I needed.
If you don't have the right equipment, go rent it or you may wish you had. |

+1 I do this all the time for getting high voltage to a ac unit. A one inch bit will have you digging it out anyway when you run sealtite or conduit through it. It's going to get caulked or sealed up, a 1/4 in larger isn't going to hurt if you miss on the first try.

I did that last weekend. My wife wanted another water spigot so I chain drilled the 1" hole with a 1/4" bit after drilling straight through the block, I cross drilled the holes then tapped the plug with a hammer.
Cake. |

My old man was a cement mason for years,he used a hammer,regular claw and hit it center on either side couple good raps of an imagained center line on a 16" block which is where the thinnest part is.Went to the other side and did same.It makes about a one inch hole.Only works well on a block in the wall already

I'm a mason. The direct center of a concrete block is the web of the block and it is solid and the strongest part of the block. Like has been said just use a hammer and if you can try and put the hole right at the bed joint of 2 blocks. This will make it much harder to shatter the block. I just hope your not trying to go through a poured cell. It's very easy you don't need to buy anything. I do it all the time. It takes about 5 seconds. |

If you want to be cheap about it use a roto- hammer like the others suggested. But a core drill is the best way to do it. You can rent one or you can call a concrete cutting company to come do it for you.
BTW I am a concrete cutter.

Do it all the time for Gas piping, Hammer drill, carbide cement 1" bit, let drill and bit do it's job at it's own pace. Easy, It'll chew thru it with no problem at all.

I think the important question is now, where is the hole in relation to your cinder block?...
I think I would just go get a damn 1" bit to drill a 1" hole... ...but Im a simply guy like that. The hammer trick is also effective. |

Well I tried the 1" bit, but used a 5/16" to drill a drill a pilot hole and make sure there was nothing behind..... one problem I couldn't find the hollow part of the cinder block
. The hardest part is the wall is covered with dry wall. I found the edge of the block, so I moved about 2" left of it, and drilled and got no where, from what I could tell i was over 1 1/4" in the block and it was still solid. My only guess was I was to close to the bottom of the block.  I gave up for the night, I had other stuff to do, so I figured I would do that later. Any tips on finding the hollow part of the block? Thanks for all the help so far, others with their sarcastic remarks (you know who you are) have way to much time on you hands ETA: Yes I know there are some hollow blocks because there is a hole in the block one up for some phone lines. |

it might not be hollow after all. sometimes it is filled with grout to make it stronger. if so, rent a hammer drill.
