Which type of saw blade is used at high speeds to soften metal for removal?

• A. Friction Blades
• B. Hard-Edge, Flexible-Back Blades
• C. Hard-Edge, Hard-Back Blades
• D. Gullet Blades

Answer: (A)

Friction blades are designed to operate at high speeds and are specifically engineered for cutting through metals by generating heat through friction. This heat softens the metal, making it easier to cut and remove material efficiently. The friction created by the blade as it spins rapidly is effective for tasks like cutting through tough materials or achieving a finer cut. In contrast, other types of saw blades typically use other cutting methodologies and are not focused on the high-speed, heat-generating properties that friction blades possess. Flexible-back and hard-back blades are generally used for different applications and may not achieve the same high cutting speeds or levels of thermal softening as friction blades. Gullet blades, while also specific in their design, serve a different function related to the clearance of chips and debris rather than cutting metal through the application of heat.
