Jig Saw Blade Materials
HHS or High Speed Steel Blades - These blades are typically the cheapest jig saw blades out there, and are meant to cut wood the majority of the time, but they can also be used for very light metal cutting.
Bi-metal Blades - Bi-metal blades are better suited to cutting metal than high speed steel jig saw blades are. They won’t cut through wood quite as fast as the steel ones however, and they are better for projects that involve both wood and metal together.
Cobalt Blades - Cobalt blades are much harder than either of the two former blades and they are used for both wood and metal cutting. These blades are more expensive than bi-metal jig saw blades or high speed steel blades but they will last much longer.
Carbide Jig saw Blades - Carbide blades are the ideal solution for any masonry cutting that you have to do. Where other blades will dull extremely fast with masonry, these blades will last for quite some time. They are more expensive than the steel or bi-metal blades, but they are worth the cost when masonry is involved.
Scrolling Blades - Scrolling blades are typically used for wood, and occasionally used for metal applications. The blade is narrower than a standard blade and is better suited for finer cutting applications. This is the best type of blade for a cut with a lot of curves involved.
Jig Saw Blade Teeth Spacing
Typically small spaced jig saw blades are used in trim applications where the cuts should be pretty. Wide spaced blades are used on rough cut projects –such as framing-because the look of the cut doesn’t matter as much and getting the project done faster is more important.
There is a lot to consider when purchasing any new jig saw blades and you can greatly improve the return on your investment by buying the best set of blades for your particular project.
