After considering the three factors.
You will need to find the required blade from the following components. Each feature of the blade is susceptible. Inside each feature, there are numerous more metrics as well. You must understand each feature very well. Otherwise, it bound your project to fail.
Remember, every type of hand saw, and power saw performance ultimately depend on its teeth type and quality.
In this article, we will discuss the finer details of each component for you so that you can find the right blade for your next project.
You should consider when buying a jigsaw blade this seven component below -
2 Main Factors Blade tooth, Blades Material
For performing cut, we have to use various types of blades depending on the necessity. So, we need a different kind of blade for cutting different elements. I will give you information about some of the blades below for your awareness.
Carbon steel blades are the most inexpensive and the most common type of blade. They are cheap and easy to manufacture. They are soft and flexible, so the users choose them for cutting through tight spaces. Moreover, because of their being soft and supple, you can easily bend them without breaking in the proper application.
They are excellent for cutting softer wood, particleboard, and plastics. Unfortunately, the teeth of a carbon steel blade are weak. So, the blades may break easily if you cut metal or stone. You can choose these blades for a quick job unless you think of durability.
This type of steel is much stronger than ordinary carbon steel. They are more heat-resistant and durable than that of carbon steel counterparts. Blades made from this material last up to five times longer than carbon steel.
The hardness of high-speed steel makes them less flexible, and so they may break while bent. They are incredibly suitable to cut hardwoods, aluminum, and non-ferrous metal without excessive wear and tear, dulling, and tooth breakage.
Bi-metal blades are more durable and made from two or more types of metal. They are a combination of a high-carbon steel body that ensures flexibility and break-resistance. They also possess high-speed steel teeth, heat-resistance, hardness, and durability.
On average, Bi-metal reciprocating blades last ten times longer than a carbon steel blade. Though the cost is slightly higher than HSS or HCS blades, they provide the versatility and toughness in performing the demanding applications.
That’s why they are the most popular type of blade among the people in the trades of auto yards, and other professions where sawzalls see frequent or daily use. You can also use Bi-metal blades for DIY projects and intermittent use as they are durable and longer-lasting.
Carbide grit blades are such a type of blades that (typically tungsten carbide) don’t have teeth like a traditional Sawzall blade. This type of blade has small particles of a carbine or industrial diamond grit along the cutting edge of the blade. It helps the blade to cut cast iron, fiberglass, cement, metal, ceramic, and clay.
The hardness of the carbide grit helps to cut these materials without damaging them or wearing out prematurely. When you use this blade to cut wood, the blade will cut very slowly and probably make a fire.
Teeth per Inch of a jigsaw blade are fundamental to consider as they fix the cutting speed and performance. However, many people are indifferent regarding this factor. Teeth per Inch on a blade may vary for material to the material.
Lower TPI means faster and rougher cutting and is better for softer materials like wood. The blades should have higher TPI for metals and other dense materials that will cut more slowly, but more finely.
Naturally, blades that have between 6 and 20 teeth per Inch are suitable for wood and other soft materials. Blades between 14 and 36 teeth per Inch are better for cutting metal and other hard materials.
Blades having over 36 teeth per Inch are satisfactory for specialty applications like tile or glass.
Length and width of the blade is an important aspect. The width of the blade is significant for its stability and the ability to cut tight curves. Usually, the blade should at least be an inch longer than the materials you will cut.
Because longer blades are durable and don’t bend at the time of cutting. So, you can cut thicker material comfortably with longer blades. The performance of cutting depends on the width and thickness of the blade. Longer blades are thicker and cut better than the thicker materials.
On the other hand, thinner blades are relatively weaker than long ones, but we can use them for cleaner and sharper curves. That is why they are ideal for cutting out delicate patterns.
