Different Cutting Methods for Granite Worktops
There are different cutting methods for granite worktops, and they include:
This method is recommended when cutting granite worktops. It involves submerging the blade into a pool of water and using it to cut through the stone. The water helps to reduce dust and cool the blade, reducing the chances of it getting too hot and damaging the granite. Although this process can take longer than other methods, it results in a smoother, more precise cut.
Pros of Wet Cutting
Wet cutting involves the use of water to cool and lubricate the cutting process. This effectively suppresses the formation of dust, which is a significant advantage, especially when working indoors or in confined spaces. The water acts as a barrier, preventing the dust particles from becoming airborne and minimizing the risk of inhalation.
Cooler Blade Temperatures
The continuous flow of water during wet cutting helps keep the blade temperature lower compared to dry cutting methods. This reduced heat generation minimizes the potential for thermal damage to the granite, such as discoloration or cracks. Cooler blade temperatures also contribute to the longevity of the blade itself, as excessive heat can cause premature wear.
Smoother, More Precise Cuts
Wet cutting tends to result in smoother and cleaner cuts on the granite worktop. The water acts as a coolant, reducing friction between the blade and the granite. This, in turn, enhances the precision of the cutting process, allowing for more accurate and well-defined cuts. The smoothness of the cuts helps achieve a higher-quality finish and makes it easier to fit the pieces together during installation.
