Core drilling refers to rounded drilling through the core of cement, concrete, masonry, brick, and stone. This type of drilling usually involves special drill bits that cut round and hollow openings in these materials, for running plumbing pipes, electrical wiring, and the like. If you’re going to be doing some core drilling on your own, note a few essential tips from the pros to make it easier and more effective.
1. Less water
When using a wet drill, keep in mind that less water is better. You may be tempted to use more water to keep the drill cool, and this is of course essential, but diamond drills work better when they can wear down so that new diamond tips are exposed. If you use too much water, there won’t be enough friction against the drill bit to expose the harder diamonds underneath, and you’ll be drilling with a worn and soft bit. Use just enough water to control heat and dust, and no more, and your drilling will go much faster and be more accurate and effective.
2. Draw an outline
When using a core drill, you need to ensure you drill directly through the material or your core will angle up or down. This can cause a problem for plumbing pipes, as this might interfere with water flow. It may also make it more difficult to thread electrical wiring through the core. To help you keep your drill even, draw an outline of the drill bit on the wall or other surface before you drill. Watch the outline as you gently guide your drill through the wall,rather than the drill bit. This can help you to concentrate on keeping the drill level and even as it makes its way through the surface.
3. Increase the bit depth slowly
Core drill bit extensions can allow you to drill the core through the wall or floor easily, but you want to increase this depth slowly. Since you typically cannot see the other side of the surface through which you’re drilling, it’s important that you use the right depth of extension. If you cannot measure the depth you need easily, increase the depth slowly, one inch or centimeter at a time. Remember that you can always continue to drill if the bit doesn’t reach deep enough, but if you drill too far, the patch or repair work can be difficult if not impossible. Don’t be overeager when it comes to drill extensions, but take your time to ensure you drill as deep as needed but no deeper.
