What are the Different Reciprocating Saw Blade Types?

There are many reciprocating saw blade types for cutting a variety of materials. The main differences are in teeth per inch (TPI), blade material, and/or blade shape.

Wood Cutting Wood Cutting Blades normally have 5 to 10 TPI and are best for cutting most types of wood, branches, and softer materials. They will also cut nails.
Demolition Demolition Blades are best for nail-embedded wood. They are thicker for heavier duty applications and range from 6 to 11 TPI. You will often see demo blades with variable TPI to better cut the range of materials encountered in a demolition job.
Combination Combination Blades also use a variable pitch tooth configuration such as 8/11 TPI or 10/14 TPI. These blades cut both wood and metal. They are good choices for many jobs because they cut a wide variety of materials.
Metal Cutting Metal Cutting Blades have more teeth per inch for cutting harder, denser materials. They are typically 10 to 18 TPI, but can go as high as 24 TPI. They are also used for finish cuts in wood because they leave a smooth edge.
Carbide Tipped Carbide Tipped Blades are for cutting very hard or dense materials such as high-strength alloys, cast iron, and stainless steel. Even though they are commonly 8 TPI, the ultra-hard and durable carbide tip allows them to cut materials that destroy other blades.
Carbide Grit Carbide Grit Blades don't have teeth - they have a grit surface used primarily for cutting tile and masonry.
