The 5-inch TCT Blade is a cutting blade designed for use with handheld circular saws or power tools that accept 5-inch blades. TCT blades are known for their durability and ability to cut through various materials with precision and efficiency. The TCT blade features teeth made of tungsten carbide, a hard and wear-resistant material. The tungsten carbide teeth are typically brazed or welded onto the blade s body, providing sharp cutting edges that can withstand the high speeds and forces involved in cutting applications.
