Reciprocating Saw Blades
How to Select the Right Reciprocating Saw Blade
Choose a reciprocating saw blade in just two steps
1. Match the reciprocating blade to the job
Bi-Metal (BiM) – This highly flexible, tough combination of HSS and HCS or Cobalt results in a blade suitable for the most demanding applications when there is a risk of breakage or when extreme versatility is required.
High Speed Steel (HSS) – Fully hardened high-speed steel blades, ideal for cutting metal, aluminum and non-ferrous metal.
High Carbon Steel (HCS) – Excellent blades for softer materials such as wood, laminated particleboard and plastics.
2. Choose the correct tooth geometry for the type of cut desired
Every material has a different density. To achieve the best possible cutting quality and the fastest cutting time, it is important to match material density with the proper blade geometry.

Reviews-
Side by side with a big box store name brand, the name brand will cut a 2 x 4 twice as fast. Durable and holds sharpness for a long time. I see they have a more aggressive 6 tooth I will try next.
I am very happily surprised at the durability of these blade. To be totally honest, I was not expecting much from such an inexpensive off brand. Boy was I mistaken. These have held up amazingly. I will definitely purchase again when needed.
Great value for the $$.
Stayed sharp trimming several fresh 2”-3” branches off a tree, and cutting all down to size for firewood.
6 pac same price as 1 blade from hardware store.

Brick like wood. Mortar like butter. Made short work of a fireplace demolition.
