Which type of circular saw blade is specially designed to cut through hard surfaces or wood?

The carbide-tipped saw blade is specifically designed for cutting through hard surfaces or wood due to its construction. The carbide tips are incredibly hard and maintain their sharp edge longer than other types of blades, which makes them ideal for cutting through tough materials. These blades provide superior performance and durability, enabling smoother cuts in hardwoods as well as in more abrasive materials.

In contrast, zinc-plated blades focus more on corrosion resistance rather than cutting capability, which limits their effectiveness for challenging materials. Kerf-bladed saws denote the width of the cut rather than a feature related to cutting through hardness and do not offer the specialized cutting ability needed for harder surfaces. Alternating-tooth blades, while useful, primarily excel in cutting softer materials and may not withstand the rigors involved with harder substances. Therefore, the carbide-tipped blade stands out as the most suitable option for those specific cutting tasks.
