Know the Type of Concrete

There are different models of diamond blades to cut different types of concrete materials. You need to pair the right diamond cutting tool for the particular concrete type. For example, some concrete is heavily reinforced with steel bars, some may have other metals inside and some structures may have been built using plain concrete only.

You need to check what all materials exist in the structure that needs to be cut so as to choose the right diamond blade for the job. The presence of hard aggregates like quartz and basalt into concrete structures demands a diamond blade with a soft bond for effective cutting.

Choose the Right Diamond Cutting Method


There are mainly two diamond cutting methods to choose from – wet diamond cutting and dry diamond cutting. Typically, diamond cutting contractors use the wet cutting method for concrete cutting projects. In the wet cutting technique, water is used as a coolant and lubricant during the cutting operation.

The use of water in concrete cutting helps prevent the diamond blade from heating up excessively and adds to its service lifespan. The technique also helps control dust production during the process. However, if it is more challenging to manage a water source at the job site, dry diamond cutting makes a perfect choice.

Getting the Right Diamond Blade for the Cutting Job

The right selection of diamond blades is essential to ensure fast, safe and accurate concrete cutting. Laser welded diamond blades or silver brazed diamond blades are preferred for wet diamond cutting operations. Laser welded blades ensure optimal performance in wet concrete cutting. What’s more, you also need to consider the horsepower of the concrete cutting saw as that can help choose the right diamond blade model.

Choose the diamond blade with a diameter that can be easily fitted inside the concrete saw you will be using for the cutting process. The arbour size of the concrete cutting saw and the diameter of the arbour hole of the diamond blade should also match each other. It is apparent that diamond concrete cutting demand extensive knowledge and a specific skill-set.

Wear the Safety Gears

Safety needs to be the topmost concern. Make sure you wear personal protective equipment (PPE) like hand gloves, goggles, ear plugs and rubber boots while undertaking a diamond concrete cutting job. Wearing protective clothing is vital to ensure your safety from any unforeseen accident at the job site.
