Looking for the Best Equipment for Taking Core Holes in Rock?

With the right tools, you can easily drill holes to make room for pipes, wires, and more without having to make multiple cuts to break up and remove cores. Read on to learn more about core drilling and how it can help you save time and get the job done right.

Diamond Core Bit(Single Type)

What a core drill does

A core drill bit is a cylindrical drill with a hollow bit that allows you to drill perfectly round holes in the material to be drilled. Since the drill bit is hollow, the drilled material is removed from the center.

Coring drills can also be used to drill through wood, masonry, stone and even ice vertically, horizontally or at an angle.

Core drilling is used in many industries for many different applications. In the construction industry, hollow core drilling is used for the creation of pipe and drainage channels, spaces for electrical wiring such as telephone and cable lines, installation of heating, ventilation and air conditioning systems, road cores, manholes, strength test holes and more.

For residential, core drilling is used for dryer vents, fireplaces, electrical and plumbing arrangements, driveway cc locations, driveway and garage drainage holes.

Different Types

Like many power tools, core drills are available in different sizes and strengths for different applications. Core drills can be handheld and equipped with small bits for use at home, while larger, more powerful bits are used for larger construction or mining projects. When drilling in concrete, Edmonton's professional concrete cutters use diamond cutting blade to reduce noise, dust and vibration.

Drill selection

The type of grounding is one of the variables that affects drill bit selection. There are several other factors to consider.

Ground hardness

The hardness of the ground is measured on a Mohs scale, which is a chart of the relative hardness of various minerals. The scale consists of numbers 1 through 10; 1 being the softest and 10 being the hardest. The drill matrix is developed to perform ideally within a certain scale, so you need to select the right drill for the hardness of the ground to be drilled.

Ground Variability

Some ground has more variability. It may soften in the first 100 feet, then become harder or break. When dealing with variable ground, there are many products on the market that offer the versatility needed to perform well in different conditions.

Variable Ground

Terrains can be broken or competent, each requiring a different type of drill bit. For example, a drill bit with deep lateral discharge is great for fractured rock because it is designed with angled waterways for better injection of drilling fluid.

You may not always be fortunate enough to know the hardness or type of ground on which to begin geotechnical drilling operations, so you should consider using coring bits that can easily adapt to different ground conditions.
