If you choose the wrong drill bit then the drilling process will take a lot longer, or you could end up damaging the bit, or, worse, the material that you are trying to drill.
Because concrete is so hard, you must use special drill bits that are either made of a strong carbide, or have diamond tips. Impact drills work a lot like normal drills, except in addition to rotational force they use percussive force to speed up the drilling process. These drills can be divided into two types: impact drills and non-impact drills. Just as with concrete sawing, there are a few different kind of concrete drills. For example, most 14 inch blades can only make five inch cuts, not seven inch cuts as you might expect. The cut will usually be significantly less than the radius of the blade. Bear in mind that while cut-off machines have circular blades that can be quite large in diameter, the depth of the cut that the blade can make is dictated by how much blade is visible past the guard. It is important that you choose the right tool for the job. This means that they are much more versatile and are an ideal choice for both heavy duty jobs and jobs that require slightly more precision. In contrast, diamond chain saws are able to cut much deeper, and can be used to make perfect corners with no over-cut. However, they can only be used for smaller cuts, and tend toproduce some over-cut.
These tools are light and easy to handle. Here is a handy guide that will help you to make sure that your work with concrete goes as smoothly as possible.Ĭoncrete saws come in two forms: cut-off machines and diamond chain saws.Ĭut-off machines have circular blades that are good for cutting smaller pieces of concrete such as paving stones. If you need to cut, saw or drill into concrete you will need to use special drills and the right safety equipment. Concrete is a difficult material to work with.
