Coring in construction refers to a very specific process. It’s not just about drilling a hole into a material. Coring is often used for material analysis, but in some cases design choices may also require coring of some sort.
Drilling a core requires the right type of tool to get the job done right. If your construction project requires coring of any type, here are several tips that will help you choose the best tool for the job:
Consider the Material
Obviously, the very first consideration in a coring project should be given to the type of material that requires drilling. Different types of material, such as concrete, asphalt, metal, or even ice, require different coring tools. Take for example, concrete, one of the most common materials to cut into. If you want a concrete coring job to be done efficiently, then you would need .
These drills are made with metal blades infused with lab-grown crystals (not natural diamonds, of course). These tools are abrasive as well as sharp enough for cutting. As a result, these tools can cut through any hard aggregates in concrete in a highly efficient manner.
Likewise, consider the material very carefully before choosing the coring tool. Some materials are easy enough to identify. But some may require a short assessment process before choosing the right coring tool.
Awkward Angle Cutting
Not all coring jobs have neat angles that cut straight into the ground below. Some coring jobs require cutting along an angle, sometimes a hard angle that difficult for most tools to get through. Technicians should consider the angle when choosing a coring drill. Most cutters of this type are designed to go through from any angle. However, it’s best to check first.
Carefully Think about Cooling
Core drills, more formally known as annular cutters, are typically cooled internally. However, it’s very necessary to use cooling lubricant with the tool, especially where the pilot pin is. The contact point of the tools can heat up real quick and make the cutting process less efficient because of overheating. Therefore, cooling is something to consider when choosing the right coring tool.
Even the best quality diamond core drill bits heat up with prolonged use. Choose the right size of tool for the job at hand to prevent any overheating issues. As mentioned above, use cooling lubricant as required. The type of lubricant to use can differ based on the tool. For example, some core drills use a cutting paste, rather than a lubricant.
The Size is Important
For this particular type of tool, the larger the size, the cheaper the annular cutter would be. Large coring tools are less expensive, so some businesses may go for the bigger tools to save up on costs. But as it is with any job, choose the size of the corer to carefully match the job at hand. An unnecessary large coring tool may cause damage to the surface. Keep that in mind when choosing the tool.
Coring jobs come in all sizes at various worksites. So choosing the right tool according to above tips is important for maintaining accuracy and efficiency.
