Final answer:
Power hack saw blades are typically made from high-speed steel (HSS) or carbon steel. Bandsaw blades can be made from a variety of materials including carbon steel, bi-metal, and carbide-tipped.
Step-by-step explanation:
Power hack saw blades are typically made from high-speed steel (HSS) or carbon steel. HSS blades are known for their durability and ability to cut through tough materials like metal. Carbon steel blades, on the other hand, are less expensive but may not last as long as HSS blades.
On the other hand, bandsaw blades are often made from a variety of materials, depending on the application. Some common materials used for bandsaw blades include carbon steel, bi-metal, and carbide-tipped. Carbon steel blades are suitable for general-purpose cutting, while bi-metal blades offer increased durability and are ideal for cutting metal. Carbide-tipped blades are the most durable and are often used for cutting abrasive materials like wood with embedded nails.
