Testing the core strength of a concrete structure is an essential part of a concrete contractor's job. As a contractor, you can do this by hiring a concrete drilling company to perform core drilling, which you can then take to a laboratory for tests. Alternatively, you can drill the core yourself and eliminate the cost of hiring an external service provider. That said, you need a high-quality core drill to help you with the process. The good news is that you can rent core drills instead of buying one given that the equipment does not come cheap. However, you must be well prepared before renting a diamond core drill. If you want to get the most out of your rental diamond core drill, you must observe the factors highlighted in this article. Read on.
The frequency of Use — How many times are you going to use the drill? This should be the first question you ask yourself before renting a diamond core drill. The reason is that frequent core drilling takes a toll on drill bits, and this will dictate the type of diamond drill bit to choose. For instance, if you plan to drill cores on one building, then you will likely use the drill only a couple of times during the rental period. In such instances, an electroplated bonded diamond drill will do the job. However, if you have to drill concrete cores on several structures over a short period, then the robust sintered diamond drill bit is the best option. If you chose the wrong drill bit, you would end up destroying the bits, thereby costing your company money.
Type of Anchorage — When using a concrete core drill, the stability of the machine is vital since it dictates the performance of the equipment. Therefore, you must examine a project's area to determine the type of equipment anchorage that is required. For example, if you are going to drill concrete cores on an uneven concrete floor, then a diamond drill with anchor points is the appropriate choice. On the other hand, if you are working on a relatively flat floor, then a core drill with suction anchorage should serve you well. Whichever form of anchorage you deem to be the best choice for your project, always ensure that you secure the equipment as directed by the manufacturer.
Safety Accessories — When using core drilling equipment, safety is of paramount importance. Therefore, it is not enough to choose a core drill with the right anchorage for the project surface. Notably, it is difficult to predict mishaps when drilling concrete surfaces. For instance, it is common for diamond drills to slip especially those with suction anchorage. You can enhance safety when using a core drill by renting the equipment with extra safety attachment. A safety chain that is attached to the drill stand is an example of an effective safety accessory that prevents the drill from falling in the event of equipment slippage.
