A core drill is one that is usually used to cut through concrete surfaces, and it may have a very large, rounded bit for making large holes. These tools are often needed when you want to run conduit, pipes, and other such materials through concrete without having to rip out the material itself. If you're in the market for a professional core drill, note a few things to look for when you're ready to shop.
1. Water tank
Water is very important in concrete cutting as it keeps the dust controlled and contained, so you have less mess and less chance of any lung irritation during your work. Water also keeps the drill bits cooler so there is less chance of damage and of injury to the user, and water also helps to expose the diamond tips of the bits. This is necessary for the drill to continue to work as you make your cuts. Look for a model with a water tank and water supply kit for cutting concrete.
A core drill should have a stand or track that you attach to the concrete in order to keep the tool level as you cut. This stand should be very sturdy and work to anchor the drill securely. Be sure you opt for a stand or anchor that is large enough to manage the weight of the drill itself and not leave it to you to keep it level and even at all times.
3. Power settings
While concrete may not be as difficult to cut through as you might imagine, not having enough power behind your drill can mean actually splitting or cracking the material as you try to push it through. At the same time, too much power can mean grinding the concrete rather than cutting it. Look for a core drill that offers a wide range of power settings so you can adjust it according to the density of the concrete and the depth of the hole you're trying to create.
If you need a core drill just for one job, you may not need one that is compatible with various bits. However, if you're looking to use the core drill for a contracting business or for a number of home renovation projects, you need to check on its compatibility with different bits. Just like a standard drill, a core drill may be limited as to the size of bits it can hold. Be sure you opt for one that is compatible with the bits you need for the work you'll be doing.
