Item #2009 Mini Saw Blade 10T 3 1/2 inch made in the USA
These are heavy duty 3 1/2 inch long blades. The 10T are best for non-ferrous metals, wood, plastic, fiberglass, and other materials. They are made from two metal types, the teeth are a harder material, which stays sharp longer. The body of the blade is a softer material which is less prone to break. Putting the two together makes for a very durable blade (bi-metal construction). They are heat treated and made in the USA.
