Abrasive cutoff saws separate material by grinding. This makes them valuable for cutting

• A. internal contours
• B. nonferrous metals
• C. external radii
• D. extremely tough or hardened material

Answer: (D)

Abrasive cutoff saws cut by grinding, using abrasive particles on the wheel to wear away the material. This grinding action is especially effective for extremely tough or hardened materials, where a regular blade would dull or chip quickly. The abrasive wheel can continuously expose new cutting edges and grind through hard alloys, tool steels, and heat-treated materials that resist conventional cutting methods. Other options would typically be achieved with different processes or tools, not the grinding action of an abrasive cutoff wheel, making them less suitable for very hard or hardened workpieces.
