A great tool for Marking Core drill holes.

When marking the layout for core drilling you have to be precise. The reason being is simple. If you layout a 100 feet worth of holes that are 5 foot on center and are off by and 1/4" by the time you go drill your 4th hole the center's will be off by an inch. This is not something that is acceptable to most Contractors who rely on your skills to hit center every time you drill. A good way to mark centers for every core drill hole is to make a cardboard outline of the size bit you are using as a template and then transfer the layout to the concrete by using a magic marker or grease pen. If the original measurements are correct the outline of the hole on the concrete surface will be much easier to see when you core drill it.

Concrete core drilling is construction type work, Commericial or residential or both.

You might wonder, exactly how does it differs from other types of construction tasks commonly used in todays modern construction methods.

Concrete core drilling with a diamond bit is the process of which one uses a large high speed drill to drill Clean, Non-destructive holes in concrete. The drill bit used to drill is hollow, which is where the core part comes in because instead of a regular hole like you get with a solid steel drill bit the center is left to be knocked out later after the desired core drilling depth is reached.

Core Drilling can be either wet or dry.

Normally we in Charlotte, NC wet core drill most materials, and use a SDS roatary hammer drill when dry drilling.

Wet core drilling involves using water as a cooling agent as the core drill bit cuts a hole the material. Most core drill bits are embedded with bits of diamonds (in the teeth of the bit only) for cutting steel and other hard substances that may be in the concrete, brick or block you are drilling.
