Which band saw blade type is generally the least expensive?

Carbon steel blades are generally the least expensive option for band saw blades. This is due to their composition, which primarily consists of carbon and steel, making them relatively inexpensive to manufacture. Carbon steel blades are sufficient for cutting a wide variety of materials, especially softer metals and wood, and they are often used in general cutting applications.

In addition to their lower cost, carbon steel blades are also easily sharpened and offer a reasonable lifespan, making them a popular choice for many users who require a cost-effective solution for their cutting needs. They do not possess the longer lifespan or durability of more advanced blade types, such as carbide blades, but for basic applications, they perform adequately without incurring the higher costs associated with more specialized blades.

Other blade types, like carbide blades, while offering superior performance and longevity, come with a higher price tag due to the more expensive materials and manufacturing processes involved. Options like brittle blades and cast aluminum blades may not be intended for the same types of cutting applications as carbon steel blades, which makes them less common for general use in band saw cutting.
