Concrete cutting in Sydney is a job that requires using the right blade alongside your cutting skills. Choosing the appropriate blade for the job could be the difference between a budget-friendly project and an out-of-pocket one. You also get to save yourself from stress and unnecessary frustration.
Unfortunately, most concrete cutters don’t get to enjoy the thrill of a smooth cutting job. Why? That’s because most of the time, they have a hard time selecting the best concrete cutting blade for their cutting jobs. Those who don’t find it difficult would tell you that they had to get used to the blades over the years.
However, you don’t need years of experience to get used to the blades; all you need is a detailed list of their uses. It doesn’t matter whether you’re a beginner or a professional; this blog post lets you in on different concrete cutting blades you can use for your concrete cutting projects. Below are the different types of concrete cutting blades you’d come across and their uses.
Abrasive blades are special blades used for concrete cutting in Sydney. They’re used for cutting rigid concrete. Sometimes, they could be used to cut metal blocks when needed. Their edges are made of a material like silicon carbide or aluminum oxide. These materials are harsh and abrasive.
The only downside to this is; the blade edges aren’t segmented. Nonetheless, if you’re looking to cut masonry, concrete slabs, or even metal, this is the blade for you.
Segmented blades get their cutting ability from their segmented diamond edges. This particular blade is designed using a rim with divided gullets. They’re known to be the strongest and fastest blades for cutting concrete.
As a result, they’re the best choice for you if you’re looking to complete a cutting job on a tight schedule. You can also use the blades for cutting through brick walls and masonry.
Dry cutting blades
Dry cutting blades are blades made from high-density alloys of diamond and silver. As of now, they’re the most popular cutting blades in Australia. You’d hardly see a construction company in Australia without a dry-cutting blade. They also come in two types such as the hot-pressed cutting blade and the cold-pressed cutting blade.
The cold-pressed ones have low-density segments with high porosity. The blades are designed this way so that cooling them becomes much more efficient. On the other hand, the hot-pressed blades are designed with high-density segments, which give them a longer lifespan compared to the cold-pressed ones.
Which cutting jobs are they good for? Dry cutting blades are ideal for cutting stones of various types and densities. Marble, granite, asphalt, concrete, ceramic, gneiss, and many other dry materials. So, when next you’re looking for the best blade to cut laterite, slate, or concrete, you should consider using dry cutting blades.
Wet-cutting diamond blades
Also known as continuous-rim blades, the wet-cutting blades are majorly used for cutting green concrete (set but not completely hardened concrete). It’s just as you imagined; the wet-cutting diamond blade is cooled using water, unlike the dry-cutting counterpart.
You should know that the diamond on the tip of the blades is coated with silver. This means it’ll be useless for cutting dry concrete. If you use the blades to cut dry concrete, the blade’s silver coating will melt quickly. Leading to the end of the blades’ service life.
The turbo-rim blade is yet another popular cutting blade found in construction sites in Australia. The diamond blades on this one are fitted with a serrated rim, which cuts through rigid material—materials like concrete and masonry.
Professional concrete cutters prefer this blade over the others because of the aggressive cutting advantage over the other blades designed with continuous rim blades.
However, you shouldn’t use this blade if your cutting job requires a smooth finish. The serrated rim of the turbo-rim blade never leaves a smooth finish on cut concrete.
Circular saw blade
The circular is one of those blades you should use when high precision is needed with your cuts. You could use the saw with either an abrasive blade or a diamond, and it’ll cut through any type of concrete with ease. It’s much preferred to the others because it leaves a really smooth finish after the cut.
Laser-welded diamond blades
The laser-welded diamond blades are the best compromise for a concrete cutter who works on both dry and wet concrete. These blades are made by fusing diamond segments and steel with laser welding. The fusion then causes the materials to melt and form a high composite that could withstand the high temperatures generated during dry cutting.
Nonetheless, you must note that working majorly on dry concrete with the laser-welded blades could hasten wear and tear on the diamond-steel fusion. If most of your concrete cuts are on dry concrete, consider going for the dry concrete cutter blades instead.
Corundum Masonry Blade (CNB)
The corundum masonry blade is made of wear-resistant steel with a rubber layer integrated inside it. You should know that the design of this blade isn’t suitable for hardcore cutting jobs. You should only use it if you’re on a job that doesn’t require cutting deep slabs. If you use it for deeper cuts, you risk shortening its service life.
