It is never wrong to use a Carbide Tipped saw blade for cutting wood. Carbide tipped saw blades cut almost everything from asbestos to Zirconium, including paper, plastics, rubber, steel, insulation, aluminum, and even food. Sure, almost any of the dozens of blade styles will actually cut all of these materials, but when you consider accuracy, finish, tool life and safety, there is no blade that will do everything.

It’s not a wonder why woodworking tradesmen and hobbyists alike are often confused. “Which blade should I use for what job? How do I make the right choice?” If you are into cutting tough or abrasive materials, or if high surface finish quality is critical then a Carbide Tipped saw blade will do the job. By understanding what factors determine how a saw blade work, you can pick out a blade that serves your purpose.

There are two primary factors to consider when deciding whether to purchase carbide-tipped blades. Those two factors are cost and durability. The durability of a carbide-tipped blade comes from tungsten carbide, a powder, electronically derived from steel that’s mixed with a binder material and fused under intense pressure at an extremely high temperature. The resultant incredibly hard material – Cemented Carbide – is then brazed to the steel blade.
