Best Sawzall Blades for Metal

Quick Evaluation Factors To Get Best Metal Sawzall Blades

The best Sawall blades for metal cutting need to be selected after considerable evaluation. If the wrong blade is bought, powering through metal can become a nightmare, as this process not only generates ample amounts of heat but can also potentially lead to blade fracture.iate

To guarantee a seamless cutting operation, choosing the best Sawzall blades for metal is essential. We have developed a personalized buying guide that encompasses all foundational factors that contribute to the decision of buying appropriate reciprocating saw blades for metal. 

That being said, here is our list for the top attributes you should consider when treading the market for some Sawzall blade-metal action:

Blade Durability

There is a reason we have featured blade durability as a top-priority factor. Given the fact that metals are dense, hard, and have a unified grain structure, getting through them requires a lot of sustained power. The blade you choose for metal cutting must have the capacity to endure the counter-stresses applied by metal being cut and be sturdy, durable, and dependable.

Strength and durability are affected by blade material. While there are blade variants such as high-carbon steel and high-speed steel, we recommend a blade made out of a mixture of metals (also known as alloy blade) or bi-material blade. These types of blades are not only durable but can also provide a much smoother cut.

Blade Thickness

Generally, tooling-experts suggest that thicker blades are more durable when put to the metal cutting test. But, arbitrarily buying thicker blades can also prove counter-productive. If you buy a blade that is too thick, it will not allow enough leverage while handling because of its weight and stiffness, and hence will fracture under sustained pressure.

Thin blades are known for their flexibility and efficiency. Because they can swivel around when making a cut, they can absorb excess bending and vibration stresses and can last longer. We recommend that you go for the best Sawzall blades for metal that are neither too thin or thick. Finding the perfect balance will guarantee you a good trade-off between stiffness and flexibility.

Teeth Per Inch

The nature of tasks determines the minimum amount of Teeth Per Inch (TPI) that must be present on cutting blades. A general tooling rule states that Sawzall blades that have less than 10 TPI, are only suitable for softer materials such as wood. These blades can be used for pruning, firewood, or other nail-embedded wood.

To select the best Sawzall blades for metal cutting, we suggest that you should look in the range of 14 TPI to 24 TPI. Dense metal projects, that require a lot of cutting power will demand a blade that has TPI greater than 18.

Blade Length

The final attribute that you need to carefully evaluate before choosing the best Sawzall blade for metal is blade-length. There is no specific recommendation for this feature because choosing an appropriate blade length depends on the nature of your project and personal preference.

As the length increases from short to long, the blade starts to lose its rigidity and power, however at the same time, it gains flexibility and heat dissipation. Given this trade off, we suggest that you select a blade length that does not compromise on aggressive cutting, while at the same time has sufficient maneuverability and heat-expendability.
