How to cut Asphalt or Concrete


With the term asphalt, relating to road paving means an artificial bituminous conglomerate, formed by a mixture of rocky materials such as crushed stone and sand. Cement, on the other hand, is the term used in construction to denote different building materials which, combined with water, exhibit adhesive properties. Both are hard products that they need suitable tools to be cut. Asphalt blades in this guide, we will see how to act.

What Tools to use for Cutting Asphalt and Cement

If you want to demolish a complex, you need something more difficult (this usually applies) than the compound itself. So, for example, if you are cutting a piece of bread or wood, a knife blade is enough to break the metal bonds of the steel to make a very strong material, such as a diamond. Technological advances have created specific tools capable of cutting parts of very robust structures (such as asphalt or concrete) thanks to the rotation of certain diamond discs. With these tools, you can achieve a linear, clean and easy cut suitable for high precision work. Depending on the work and therefore the cut to be made on your piece of concrete or asphalt, the blades have different shapes and sizes: small (around 200 millimeters),

Depending on the use for which you purchase these tools, you can opt for a wet or dry cutting mechanism (if you are not an expert, you can know the difference between the two methods on the internet or visit a hardware store. industry expert). Regarding prices, the cost of this type of instrument is quite high (we are talking about at least one hundred euros); therefore, before purchasing them, you will need to appropriately educate yourself on what is best for you. Diamond tips, by virtue of their chemical and physical composition, are hardly subject to wear and remain unchanged, both in terms of quality and function. Excellent maintenance is not necessary.

  • How to use Diamond Tips to cut Asphalt or Concrete

Road workers generally use diamond tips: this equipment is very precise and dangerous and should only be used by expert hands or by those who have been properly instructed and instructed in its operation. We strongly advise against using certain equipment when you are not sure what you are doing or how the machine may react in certain stressful or stressful situations.

The Types of Blades for Cutting Concrete

In this part of the article, we’ll take a look at the different types of blades used for circular saws or grinders and what they are used for:

Abrasive Blades for Masonry

These types of blades are generally quite inexpensive – a 7 ″ blade will cost you less than $ 5. They are widely available and can be used to cut asphalt, stucco, as well as concrete. Unfortunately, the low cost of abrasive corundum blades negatively affects their speed, as they are only able to cut shallow passages from 1/2 ″ to 1/4 ″. Cutting with them can be time consuming and they also wear out quite quickly.

A 7 ″ abrasive corundum blade will wear up to 6 1/2 ″ after cutting a foot or two along your cut line. This means that the operator must frequently change the depth of the saw in order to expose more of the blade. Asphalt blades these types of blades create dust plumes and usually get so hot that they glow. But they’re still the best choice for people on a budget and for those who only need a few shallow cuts

Diamond blades

These types of blades feature a metal blade that is coupled to a diamond or a metal composite. When in use, their metallic composite slowly wears away and reveals a cool, sharp diamond edge. Buying a diamond blade for your 7 ″ circular saw can be a huge investment, but you can be sure that it will outlast an abrasive type blade – it’s a perfect choice for those who cut a lot. of concrete.

They can be Separated into two Distinct Categories:

Dry Diamond Blades: These usually have toothed or serrated rims that help them eject waste and cool the blade. They are exceptionally well suited for making deeper and deeper cuts. Their biggest drawback is that they create a lot of fine dust. When used indoors, seal the entire work area with duct tape.
