![]() ![]() Even at a lower speed, they can plow through the concrete just fine and create the opening you need. ![]() Thanks to that design, the whole drill bit can work through the sheet of concrete more effectively.įurthermore, masonry drill bits don’t have to be deployed at high speeds to work well. As noted by How Stuff Works, masonry drill bits use tips that are larger in diameter than their shafts. Masonry drill bits are best to use on concrete for a few reasons.įirst, the design of a masonry drill bit is great for working through the concrete. You then need several masonry drill bits that are compatible with your drill. ![]() The regular drill is obviously the first tool you will need. When it’s strengthened further by the aggregates, drilling into the concrete becomes a very difficult task. The hardened paste alone is already a strong material. Now, imagine having to drill into all of that. That mass is what we know as concrete and its strength should not be surprising considering its composition. Once the paste starts to harden over the aggregates through hydration, it forms a stronger and more durable mass. The paste is usually made from Portland cement and water and it’s then used to coat the aggregates. The paste is the other component of the concrete and it is just as important when it comes to imbuing strength. Concrete manufacturers also make sure to use clean materials in order to maintain the strength of the aggregates. Bits of gravel and crushed stone are commonly used to make the coarse aggregates. Meanwhile, the coarse aggregates consist of particles larger than 0.19 inches. The crushed stones and sand grains must be small enough to pass through a 3/8-inch sieve before they can be used. Two different kinds of aggregate are used to make concrete.įirst, you have fine aggregates and they are typically made using crushed stones or sand. They specifically account for about 60 to 75 percent of the concrete. The aggregates make up most of the concrete. Instead, it’s a mixture of both aggregates and paste, according to. For starters, you should know that concrete is not just one kind of material. Have you ever wondered about what concrete actually is? Well, allow us to tell you more about it. ![]()
