New artwork at 631 Cross Trail Dr. Greenway.

Today we got to do some crossover work and show our creative side as we core drilled some 5-inch holes in concrete so that a new flamboyant and stylish swing that has been installed at 631 Jackson St. in Charlotte, NC. Not that we are not already artists in our own right. This particular project made us proud to be able to work with different people who take the time to appreciate the crafter side of life in their work.


This has become one of our most popular photos.

Core drilling a brick wall on a ladder

This year 2021 has seen an uptick in the number of core drill holes we do for data companies. It seems every fourth in-coming phone call is from a customer that needs to run data lines for the 5G service. Whether it be for a multi-story building, a grocery store, college, bus station, or home. Everyone wants the fastest internet connection possible in their area. This core drilling project occurred on Margret Wallace rd in Matthews, North Carolina. A tough job, to say the least when a 4-foot deep ditch is below you and you have to use a ladder to bore a 5-inch hole through a 20-inch brick wall. Most of the time our company policy is to try to lock the core drill rig to the wall to make drilling a smooth perfect hole look easy. Not all the time is this policy able to be enforced. This particular brick wall was too brittle to hold the weight of the core drill rig so it was hand-core drilling we had to go. Never mind that below the area where the holes need to go was a ditch dug out with rebar sticking straight up like spears ready for piercing. Much like a horror story in a Hollywood movie

5" template

I often use a carbide-tipped hole saw with a masonry centering bit to start a template for the holes when using our handheld motor. In place of that, I also set the lite wall rig on the floor with some cardboard underneath to allow tracing of a cardboard temple to be used to mark each hole and distance center to center of each hole to be transferred to the inside wall to make sure everything matched up. A five-inch bit is quite the heavy bit to use when mounted on a hand-held core drill motor. I do not recommend it, but with a little patience and experience, we were able to make these pretty bore drilled 5-inch holes through the brick wall.

Of course, you say I can see your rig firmly mounted on the brick wall in the picture. Well, that was the only one we were able to mount too and use the rig, the others were hand-core drilled. I made another pre-cut cardboard template like the one that had been created earlier to mount the core drill in the picture at the upside-down position that it is in. Getting the core drill rig, motor, and bit with all the accessories needed to make the hole turned out not to be the most fun job to say the least. If you ever try to mount a core rig upside down then you know what I mean. Topping off the challenge of core drilling a brick wall was the fact it had to match the pre-determined cut-outs of the already set up electric panel that was installed inside on the other side of the wall. I forgot to get a picture of the inside of the wall but I tell the truth when I tell ya I nailed it dead center each and every hole.

Core drilling a house foundation in North Carolina

What a hole. Not so much the 5-inch core drill hole through the foundation in Connelly Springs NC, but the hill or better yet small mountain that had to be traversed to walk down to it.Most of our projects in North Carolina are within 100 to 150 feet of our 2006 ford work truck which houses our generator and water supply for core drilling projects in remote areas. But this hill declined more than 250 feet down a Carolina red clay mudslide to the back of a newly constructed home beside the river of the main road of Connelly Springs.

Up, Down, Up again

It took 5 pain-staking trips up and back down the muddy mess to accomplish our mission of getting our customer a penetration through the 16-inch foundation wall where the drain lines for the home to the local sewer systems could be passed. Nobody was happy about the walking, but I would have been even unhappier if for some reason we did not complete our mission and failed to drill a hole through the house's foundation.

After all the walking we finally got set up. the time it took to push the bit through the wall was about 10 minutes. I was tired from all the going up and down the hill.

Fast core drilling in North Carolina

Sometimes on large jobs, we get to test our mettle and see how many holes we can drill on an average worksite day. Out of core drilling the 202 total holes on a concrete platform, this particular day we racked up 77 holes. No small feat as this was done between the times of 7:30 AM and 5:00 PM, or a little less than 10 hours. A general average of 8 holes an hour is the amount of time it took. Of course this not top speed for us, but a pretty good lick nonetheless. Our plumber, for which we were coring, laid out the holes, and we, Carolina Precision Core drilling, set to get them done.

Most of the holes were between 2 inches and 6 inches core drill bit size, luckily we were able to advance in blocks of rooms with holes the same size that leads to being able to drill one size in a single pass with each bit. In other words, we drilled all the 2-inch holes for four rooms and then all of the 3-inch core drill holes for the same four rooms, etc. I know, I know,..you say 77 core drill holes is not really all that great of a number for a daily totals worth of work. But consider, this entire event took place with water, power, and tools. Laying out the holes, ie: I like to draw pretty circles around the centers of each size hole to make it easier to tell where the hole is and where it should be drilled. Actually doing the drilling, and of course in cases of redrilling where obstacles that might inhibit the path of the PVC water lines and drain pipes had been found below the podiums concrete floor. Obstacles, by which I mean are steel beams that hold up the 2nd floor. Total project teardown, and repacking everything back into the truck, and last but not least throwing the cores in the dumpster for clean up.

This was all done by 1 man and his wife.

Professional core drilling indeed.

Naturally, this could not be done by any novice core drill operator but we have experience in these matters, always wanted to say that, like Zemo on the avengers, or close enough if that is not the exact quote. The next week of April 2021 we finished most of the rest of the job by putting 31 total 7-inch, 6-inch, 3-inch, and 2-inch holes in the upper podium courtyard, all in one shorter day of course. But this particular day it took about 6 hours to finish up the 2nd-floor podium. Not the greatest time, for now, our average was down to less than 4 holes and hour but heck, sometimes setting up is a good 25 percent to forty percent of the time spent for each job anyway. thriving for efficiency and accuracy is our goal, and anytime that we make a completion we are grateful to have the opportunity to do so. Thank you, General contractors of North Carolina, we are daily grateful for the opportunity to provide excellent core drilling services to you.

The 24-inch holes you see here

for the new sams express car wash on Providence Rd, Waxhaw, NC needed some more core drill holes in them because they did not come from the concrete fabrication plant as needed. Often we perform core drilling services for plumbers who need more holes in the concrete slug boxes or water basins than the engineer called for. These 5-inch holes were just the size needed to ensure that a 4-inch pipe would pass through for plumbing.

The week of Xmas in the year 2020

found us in the North Carolina town of Mooresville NC core drilling a cement block wall. The 5-inch core drill holes in the block wall were about 9 feet off the ground level, which makes this type of core drilling with a wall rig and motor that weighs app 163 lbs a dangerous endeavor. We have developed a special method for core drilling this large a=of a hole in a wall of this type. We use concrete sleeve anchors, along with a combination of concrete wedge anchors to secure the base and mast of the core drill rig to the wall and then the motor and bit. Never once have we used what is referred to as drop-in anchors that do not drive as deep into the wall to hold the rig. Whether or not you decide to use a drop-in type of concrete fastener or the wedge anchor, or the concrete sleeve, you want your rig to stay fastened to the walls.

The 5 inch core drill holes in the block wall were for new gas lines at the newly constructed Duke medical center on Arlington Dr. Most cement block walls are poured with concrete and rebar every other block or 16 inches, sometimes every 24 inches depending the load weigh of the wall itself. The height of this particular hole on the wall made it a great project to teach some core drilling skills to one of our young core drill operators that is eager to learn the trade.]]> 5-inch Thu, 18 Jun 2020 16:36:11 EDT <![CDATA[Products - 5 inch wet cutting core drilling bit]]> https://core-drill-bit.com/sizes/5-inch/5-inch-wet-cutting-core-drilling-bit-14.html https://core-drill-bit.com/sizes/5-inch/5-inch-wet-cutting-core-drilling-bit-14.html

5 inch concrete core drilling bit for sale. Price $190.00

This is our core drill bit drilling a brick wall for a local contractor in Winston Salem, NC. The Video is one of our core drilling crew core drilling a foundation wall for a 4-inch PVC pipe so the hole had to be 5" in diameter. Many plumbers, electricians HVAC, pipefitters, and such often will give the pipe size when explaining the size hole that is needed. A skilled core drill operator should always ask if that is the size of the hole, Right? Not the pipe.

A five-inch core will not usually popped, that is break off evenly at the bottom, unless the hole drilling depth is a least 5 ich or more.
