When one looks at the core drills today, it is hard to believe that the earliest core drills were in use in 3000 BC. The first to use the core drilling process were the ancient Egyptians. Today, core drills have advanced a lot and are used in various applications and for different purposes. You are just on the right page if looking for useful information on the core drilling process.

What Is A Core Drill?
A core drill is a device that is precisely planned to get rid of a tube of material, and whatever is left inside is referred to as a core. The body of the core drill looks like a hollow cylinder, which is used to make holes through a surface. It is made of a motor, handles, and drill bits. The tip of the drill may be coated with diamond or carbide.
These drills are used in applications where there is a need to preserve the core. At times, the core drilling procedure is used in mineral exploration, where the drill has to penetrate several thousand feet in depth. The core drill can pierce various types of surfaces and to different depths. You can use the drill on wood, rocks, cement, concrete, and ice. Today, based on the needs and applications, there are various types of core drills in the industry or market. Some of them are discussed below:
- Annular Cutters – The core drills used in metals are called annular cutters and they can cut a groove at the periphery of the hole. These cutters are available in different diameters.
- Diamond Core Drills – The core drills used for concrete are water-cooled and are known as Diamond Core Drills. The diamond core drills are commonly used in the construction sites for making pipes and holes in concrete.
- Carbide Core Drills-The carbide core drills are used for drilling masonry applications. These drills carry a specially engineered design that can work in solid or cored casting conditions.
For standard drilling procedures at home, one can use a medium-sized drill. However, you may need a much larger and powerful core drilling machine for tougher operations in massive construction projects. When you operate a core drilling process, you find several choices to run the drill, and these include pneumatic, hydraulic, and electric. One may need different drill bit, based on the surface to be penetrated. The aim is to get the optimum results and the best performance when core drilling. The two major types of drilling bits are roller bits and fixed cutter bits.

The Depth of Core Drilling
How deep the core drilling equipment is expected to go depends on the structure of the equipment. Whatever the surface and the depth required; the diameter of a core sample should be three times the nominal size of aggregate. It is essential that the core samples are appropriately labelled and strode for further use. The core drilling bit should be suitable for the kind of drilling required. At times, there is a borehole camera that can indeed be helpful to see the inner condition of the structure.
Drilling is a common procedure in significant construction projects as one needs to make holes for electrical wiring, anchor bolts, and drains. Drilling metals and concrete is a task that is best left to the competent professionals in core drilling. When you hire a core drilling company, learn about its past projects and perfectness. Read reviews and get referrals and ask others before you go ahead. They should be well aware of the latest technologies used in core drilling and how to set up and maintain rigs. The company should carry the expertise and experience of working with different types of core drilling and have a team of trained and experienced employees.
