Reciprocating saws are highly powered saws that achieve their cutting action through a push-and-pull motion. Reciprocating saws are similar in their design, often coming with a foot that rests on the surface you’re cutting. The point of the foot is to ensure the blade doesn’t move away from the cut while working.
It might be popular knowledge that the blade in this kind of saw differs in terms of their material. But do you know the material can affect the other components such as strength and speed? If you’re an independent user, a material supplier, or even a long-time professional, this article aims at helping you decide between two common materials used in reciprocating saws, steel, and carbide. We’ll do this by comparing them based on specific criteria.

1.Reciprocal Saw Blades-Strength and Toughness
In terms of strength and toughness, steel and carbide reciprocal saw blades differ widely. This property affects the kind of material they cut. On one end of the spectrum, carbide is one of the most hardened blades. It is much harder than steel and lasts much longer as well. This feature makes it ideal for going through equally as hard material. They can cut through high-density alloys like cast iron or binding materials like nails. This strength adds to carbide’s resistance to wearing out and needing to replace the blade.
On the other hand, all that strength won’t be of much use when working with wood. Carbide tends to cut through wood slower when compared to steel. Steel is not as hard as carbide; therefore, using it on certain metals would quickly destroy its blade. High Carbon Steel is even considered one of the softest blade materials. Although High-Speed Steel is slightly stronger, at best, it cuts through non-ferrous metal like Aluminum. But steel is an excellent choice for cutting through soft material like wood and plastic.

2.Reciprocal Saw Blades-Speed
When it comes to reciprocal saw blades, the fewer the tooth count, the faster it’ll be. However, this doesn’t displace the function of a property of the material in terms of speed. Very few blades can match up with bi-metal in terms of speed. But carbide does well enough in this department to be considered for speed amongst reciprocal saws. Carbide blades easily cut through materials faster than steel does. It exhibits a high resistance to vibration and impact, that allows it to stay sharper for longer and cut through metals faster.
In other words, the speed also means it possesses more of an occupational hazard. Therefore, operating with great caution when using it is essential. Its speed makes it sacrifice in the department of smooth edges. So, although carbide is excellent for getting the job done quickly, one has to bear with rough edges. If you’re not time conscious and looking to finish your project with a more delicate finish, steel is the way. Steel blades offer less speed that their carbide counterpart. But by cutting slower, it allows the edges of the material to be smoother.

3.Reciprocal Saw Blades-Flexibility
The flexibility of a metal determines the metal’s ability to resist bending without breaking. When comparing steel and carbide in this respect, there is an obvious winner. Steel is considered one of the most flexible metals, which allows its uses as a blade to be numerous. Now keep in mind that there are two kinds of steel blades used in reciprocal saws. There’s High Carbon Steel, known as HCS and High-Speed Steel, known as HSS.
HCS and HSS have similar but varying features, including flexibility. HCS is the one commonly referred to when steel receives praise for its flexibility. Its bendability makes it essential in the cutting of particular material because it allows bending. HSS, on the other hand, is less flexible and thus more prone to breaking. However, when comparing carbide to both HSS and HCS in its ability to bend, carbide ranks lower. It is harder than both steel types of metals and thus more resistant to warping during cutting. The length of a blade can also affect its flexibility.

4.Heat and Impact resistance
As mentioned earlier, reciprocal saw blades made of steel may be of two types. The two classes being High Carbon Steel(HCS)and High-Speed Steel(HSS). They share similar properties, but just like in their flexibility, they have other differences. Among these differences include their resistance to heat and impact.
A metal’s ability to tolerate a lot of heat and impact has a high correlation with its strength. That simply means more durable materials can withstand pressure, temperature, and impact better than blades made from lighter materials. As a result, HSS is more heat resistant than HCS. In turn, carbide is more resistant to heat and impact than both HCS and HSS.
How does this affect their performance, you might ask? Well, the added strength and resistance of carbide, means it can go through heavy metals almost seamlessly. In contrast, steel with lower resistance to heat and impact works best when cutting through wood, plastic, and non-ferrous materials.

Several factors can influence the longevity of a reciprocal saw blades. Not all elements are exclusive to the make and material of the blade. Examples of these factors are; how often the edge is in use and the kind of stuff it cuts. How well the user preserves the blade, and the manufacturer can also affect its lifespan. When it comes to the internal features of the blade, just as many factors determine its durability.
Carbide blades tend to last longer than steel blades. It is due to many properties of carbide that steel does not possess. Carbide is thicker and more durable; the significant increase in its thickness makes it more durable.
The depth of a blade is inversely proportional to the flexibility. Thus, in addition to being more sustainable, carbide possesses less flexibility and higher resistance to bending. By being a more hardened and less flexible material, carbide is less prone to wear and tear. These features make carbide more excellent for long term use.
It is also important to know that strengths such as thickness, which make it more durable, also make it more expensive. Whereas steel, which is less sustainable due to its lightness and high flexibility, is cheaper. Although steel’s flexibility makes it useful on several materials. Its light natures limit its use on certain elements based on strength. Thus, it can easily break when used on harder metals.

Steel and carbide vary significantly in their unique features. We’ve seen how these features can effortlessly intertwine and affect other functions. Such as how the lightness of steel makes it more flexible and easily bendable. We’ve also seen how the hardness and toughness of carbide make it more durable and resistant to heat. Consider the fact that these properties all have their pros and cons. Ensure you account for these while working on any job or project.
When dealing with hard and dense materials, carbide shows better resilience due to its strength and impact resistance. This strength, however, can be a drag when working on wood. Jobs that require a blade to be more flexible, however, benefit more from a steel blade. In addition to that, projects requiring a neater finish also benefit from a steel blade. In terms of durability, carbide outshines steel, which makes it better for ongoing projects. Steel, however, is more economical so that it might be a better investment for small and sparse projects.
On a final note, steel and carbide are both familiar and excellent materials for a reciprocal blade. Now that you know how to choose between carbide and steel effectively. You should also keep in mind that it’s just as essential to get these blades from the right source. Your projects are likely to suffer, and you’re not going to get the best from blades of poor quality.
