Blade Material: What Jigsaw blades are made of ?

All the Jigsaw overalls used (Corded or cordless jigsaw) have the same type of blades. Among the four fundamental types of blade materials, select the right one according to your cutting materials (task):

  • High-speed steel (HSS)
  • High carbon steel (HCS)
  • Bi-metal
  • Tungsten carbide

High-speed steel (HSS)

From the name, you may guess the efficient cutting of these blades. Though these blades will give you a smart finishing, the blades are prone to damage from the heat.

High carbon steel (HCS)

High carbon steel blades are more durable they are made with HCS since carbon is the hardest element. The amazing part of using the HSC blade is its flexible nature. Because of the strength and harness nature of HCS, they are perfect for edge retention.

HSC blades are inexpensive, allowing you to buy in bulk for your household or other DIY purposes. However, HSC blades are also less durable than HSS.  Because of the absence of chromium, the jigsaw made with HSC has poor rust resistance ability.


From the name bi-metal, you may guess that two types of metals are used in this jigsaw blade. Yes, you are right. Both carbon steel and high-speed steel teeth are used to develop the blade, allowing you to enjoy the advantages of both types of metal blades.

You can use a bi-metal jigsaw blade for hard woodcutting and metals. Most importantly, bi-metal blades have to wear resistance and are flexible in nature.

Tungsten carbide

These blades are the most durable among all in the market. These types of jigsaw are coated with tungsten carbide grit instead of teethes that are commonly used in other types of blades. Manufacturers are developing these types of jigsaw to use for ceramics, steel, or fiberglass.

What is teeth per inch (TPI) of Jigsaw blades?

You need to know a few basic facts before selecting the proper blade. What type of material do you plan to cut? Is it wood, metal, plastic, laminate, ceramic, or fiberglass? What type of cuts will you be making tight cuts, rough cuts, or a combination?

The number of teeth a cutting edge has will influence both the speed and nature of the cut it can produce.  Sharp edges with fewer teeth will deliver a quicker, rougher cut, while those with more teeth cut the more gradually but make a smoother finish.

One of the most important things to consider is the number of blade teeth per inch. Most woodcutting blades have 12 teeth per inch, while metal-cutting blades may have up to 36. Generally, the fewer the teeth, the faster the blade will cut. However, blades with fewer teeth also mean a rougher cut.

For your conscience, TPI or teeth per inch is essential for an extreme performance, which is the number of “teeth” of your blades. The higher TPI offers higher perfection and smooth cut.

  • TPI of between 6 and 20
  • TPI of between 14 and 36.

What is the tooth direction of blades?

Blade direction is one of the most important for Perfect Cutting. Most of the jigsaw blades designed to cut on the upstroke and have teeth that point towards the shank; however, you can likewise purchase a jigsaw blade with a reverse shape.

It’s called down-cut or reverses tooth blades. We need the reverses tooth blade to cut some different materials or some exclusive designs.

What is Blade's length?

Always Choose the correct length for the material being cut. Never try to make a partial depth cut with a jigsaw. It may damage the blade or your saw, if the blade that is too short to entirely cut the workpiece. It is essential to use a saw blade that is long enough, excluding the cutting surfers' thickness.       

Length of a best jigsaw blades cutting edge is showed by the length of the body that has teeth however, It excludes the upper shank that fits inside the sharp edge holder — the example below shows a 75 mm cutting edge.

The proper length of the sharp edge is 54 mm (2⅛”), which is 75 mm short of the 19 mm that does not stretch out beneath the saw’s sole plate.
