Choosing the right reciprocating saw blades for your unit may be a bit confusing, for there are a lot of types and manufacturers out there that promise you the best results. However, one should always be aware of the features that your project requires. There are various types of blades that can be used for assorted materials.
Common Types of Reciprocating Saw Blades
- Carbide Grit used for cast iron, ceramic tiles, clay pipe, stone brick, plaster marble and fiberglass
- Demolition/Heavy-Duty blades come in different TPI and are used in different materials, but mainly for heavy duty pipe and stainless steel
- Metal-Cutting, which are blades that can also be used on stainless steel metals, non ferrous metals, hard rubbers, and structural steel
- Wood-Cutting blades are the ones you use on thick nail embedded woods
There are also special types that are designed for specific materials like drywall or pruning application. The Bi-directional blade is a type of blade that cuts in both directions. This type is used for faster cutting. The Tapered back blade, on the other hand, is for plunge cuts, which allow you to directly cut the surface without having to start at the edge.
Choosing the Right Reciprocating Saw Blade
There are many factors that one needs to consider when getting the right reciprocating blade for your unit and they are as listed below:
Know what type of material you will be using this blade for, in order to narrow down your search.
You may have a manufacturer that you trust with tools that you need. There are many manufacturers out there, so you had better know which one to trust.
You need to consider the size of your project, and whether it requires a long blades that has more TPI. A longer blade for short materials will likely cause damage to your project. However, a shorter blade will wrap within the material and can bend or snap the blade, so you must be aware of the right size of the blade before using it.
Like with any other tools, the blades must have the same fitting or locking mechanism with your unit. There are many different kinds of fittings for various reciprocating saw units out there.
There are three types of dimensions when looking for a saw blade: the length, width, and thickness. The common blade ranges from 3 to 12 inches. Longer blades make deeper cuts, so you need to know the depth of the cuts you intend to use it for.
The blades have TPI, or the Teeth per Inch, which basically represents how tough a blade is; the fewer the teeth, the rougher the cut. So if you prefer a smoother cut, choose one that has enough TPI. Larger TPI blades make rough cuts on materials and abrasive blades do not have teeth, but can cut easily and smoothly on metals.
