Jigsaw Blades! That’s what we will present with an infographic. Knowing about Jigsaw or Cordless Jigsaw are never enough for a woodworker or a carpenter. Well, they are essential, but we often ignore the most fundamental topics with the power of reviews.

That will not happen today.

We will talk about the principal of a jigsaw blade. Your cutting performance and perfection depend on the jigsaw blade. Your money will be a total waste if you cannot be able to pick the right module.

So, what makes a blade great?

Consider; First – blade-shank, T-shank and U-shank are there in the market. After that, it uses the materials to make the blade and teeth per inch or TPI.

The number of teeth a cutting edge has will influence both the speed and nature of the cut it can create. However, you needing to consciously pick the blade based on the materials you need to cut such as wood, ceramics, etc.

We describe in the article 6 Principal of a jigsaw blade-

  • Blade type
  • Blade Material
  • Blade teeth (TPI)
  • Tooth direction
  • Blade length
  • Flush Cutting Blades

The good news for you is how we have arranged in this article with an infographic that increases your knowledge for any cutting situation. Our designers wanted to make sure that you get a visual image that jigsaw blades will perfect for your job. So here, you go.

Enjoy the visuals.

What is the Shank of Jigsaw blades?

It’s worth remembering that every jigsaw blade will not fit with every jigsaw clamp!

We classify the blades according to their shanks, and these shanks are only compatible with particular types of jigsaws. There are also models that are consistent with multiple shank types. However, most of the standard ones only accept the particular one.

Checking the manual of your jigsaw will help you to understand the shank type. You should select for your jigsaw based on your choice, which is fit for your jigsaw (machine).  Jigsaw-shank types are separated into two major classes. They are-

  • U shank (universal shank)
  • T shank (tang shank)

Let’s know each of these types in detail.

T- Shank blades

Most manufacturers are now using T-shank blades as a standard, which makes it easier to switch blades between different machines. T-shank blades come with a tang at the top of their shank that fits into blade clamp of the jigsaw.

Let’s replace the T-shank blade doesn’t need more than a simple push of a jigsaw button. Offer you a quick and easy to replace jigsaw blades with no hassle.

Many of the U-shank jigsaws are also compatible with T-shank blades. These types of blades are compatible with most of the modern jigsaws available in the markets nowadays.

Users may get more benefits as suitable in using time and save time.

Wow! It gets popularity for its character.

U-shank blades

The U-shaped characterizes U-shank edges cut out at the top of their shank. This older jigsaw machines must have a hole in the shank just below the U-shaped cut-out.

It is now the oldest one who spends much time at the time of blade changing, and users get irritation. Otherwise, u-shank blades changing time, users need extra tools.

U-shank blades are still available although the T-shank has become more popular it now fit as Today.

What is the material of Jigsaw blades?

Among the four essential types of blade materials, you should select the right one according to your cutting materials:

High-speed steel (HSS): From the name, you may understand the efficient cutting of the blades. Though these types of steel give you smart finishing, the blades are prone to damage by heat.

High carbon steel (HSC): High carbon steel blades are more durable blades made with HSC since carbon is the hardest element. The amazing part of using HSC blade is its flexible nature. Because of the strength and harness nature of HSC, 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 less durable than HSS.  Because of the absence of chromium, the jigsaw made with HSC has poor rust resistance ability.

Bi-metal: 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.

Youcan use a bi-metal jigsaw blade for hard woodcutting and metals. Finally, bi-metal jigsaw blades wear resistance and are flexible in nature.

Tungsten carbide: These blades are the most durable than the others in the market. These types of jigsaw are coated by tungsten carbide grit instead of teeth 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 TPI of Jigsaw blades?

You need to know a few basics facts before selecting the proper blade. What type of material do you plan to cut 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?

What is Blade length?

Always Chose 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 of entirely cut the workpiece. It is essential to use a saw blade that is long enough, excluding cutting surfers thickness.

Length of a jigsaw cutting edge is showed by the length of the body that has teeth however excludes the upper shank that fits inside the sharp edge holder — the precedent beneath shows a 75 mm cutting edge.

Theproper length of this 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, less.

What is Flush cutting blades?

Flush cutting feature Just introduced a few jigsaws, allows you to can slice up to a vertical surface.

Notwithstanding, it is fundamental to note a few of jigsaws, those that have shoes are Closed at the front, can’t be used with this edge. If you are expecting flush cutting with a sharp master edge, ensure that your jigsaw allows a flush cutting edge.


Hopefully, you get enough information about jigsaw blade. It still confuses if you don’t worry. Read this article and follow the info graph that will learn your technical issue and features about jigsaw blades.

This infographic also helps you think through each feature and how it relates to your necessities. This article also more informative.
