Core drilling can be a little daunting, especially if you are not used to it. While it is advisable to seek the assistance of a professional core driller, you might sometimes feel like you are up to the challenge. In such a case, you need to get ready with the equipment and follow the following tips for a successful job.
There are a variety of drilling machines available in the market, and you should choose depending on your needs. Also, you might consider either buying a personal machine or rent one depending on the regularity of your use. Either way, you need to ensure the equipment you pick is perfect for the job.
You can choose either a handheld drill which makes 3 inches holes or a rig mounted drill which makes 3.7 inches hole, the latter is more efficient compared to the previous. For someone considering to purchase a core drill, it is important to go for the one that offers multi-purposes to help you get the value for your money.
Core drills are powered using either electric, hydraulic or air powered sources. You need to know your working environment to pick the right core drilling equipment. While drilling, you should consider pushing the drill motor to its maximum amperage but do not exceed the limit. Exceeding might cause the engine to be bogged down hence lowering its production.
If you are using a wet core drill, it is important to know the right amount of water to use. It is possible to think that with more water, you get faster drilling but this is wrong. Water is supposed to make the concrete slurry by mixing the debris with the concrete dust. The mud keeps the diamond exposed as well as keeping the core cool.
Using too much water might end up washing away the dust particles away hence nothing to keep the ring exposed. A Little water, on the other hand, leaves nothing to create the slurry and hence the ring keeps on grinding the same particles. As a professional core driller, you should know when to add water and the right amount to add.
If you are handling regular core drillings, then a simple 1 foot long bit will be perfect. However, if you are handling drills higher than this, you should consider using barrel bits as they allow deeper core drilling. Depending on your depth requirements changes, you should consider using drilling extensions.
