Drilling a hole in concrete for an anchor doesn't have to be a back-breaking task. Manufacturers have introduced a number of drill bits specially made for cutting through tough concrete and the concrete anchors themselves come in a number of styles and shapes, depending on the task you have at hand. As with any other project, the important part in drilling concrete anchors is making sure you have the right tools and have planned for the job.
Things You'll Need
- Concrete drill bits
- Compressed air or vacuum
Mark the spot where you want to place an anchor in the concrete using the chalk.
Attach a masonry bit to your drill. The size of your drill will depend on the type of anchor you are using. For a split drive, strike anchor or metal hit anchor, you will need a drill bit the same size as the anchor. For other anchors, follow the manufacturer's instructions.
Press the drill against the wall and begin drilling. Apply steady pressure in order to push the bit through the concrete.
Remove the drill bit from the hole and brush away any gathered dust and debris with the compressed air or vacuum.
Repeat the process until the hole has been drilled to the required depth.
Tips & Warnings
- Ensure that you will be drilling in the right spot. Check your measurements twice. Drilling anchors in concrete can take a while and it's not the type of job you want to do twice. It's much easier to drill in the mortar holding concrete blocks together than the blocks themselves. If you're drilling a larger diameter hole (more than 1/2 inch) you might want to use a hammer drill. These operate like mini-jackhammers to make drilling through concrete easier. You can rent them by the hour from most hardware stores.
- Use caution when taking the drill bit out of the hole, as it will be very hot. Be sure to use safety glasses and other safety equipment when working with power tools.
