A reciprocating saw is a lot better in performance rather than a traditional saw. It works faster and you can cut anything without exerting much pressure. Fiberglass has abrasive characteristics. While selecting a reciprocating saw blade, consider these characteristics for a refined cutting. For the cutting of fiberglass, the blade with carbide-tip has a great performance. Since the fiberglass is hard to cut in refined form, a sharp and high-quality metal blade is required for it. You can select any blade from our list because all of them are compatible with universal reciprocating saws. Furthermore, the selection consists of reliable and trustworthy brands.

Buying Guide
The reciprocating saw has a long history, but it is still one of the most useful power tools around. From basic construction work to cutting up sheet goods in the shop, a reciprocating saw is a tool that everyone needs in their box. However, finding the right tool for the job isn’t always easy. For most home improvement projects, a basic saw with a few different blades is all you need.
There are a number of factors that go into choosing the right blade for your reciprocating saw. These include the material you plan to cut, the type of blade (carbide, diamond, etc.), and how you plan to use the saw. For instance, you may want to use a carbide blade to cut stone, but a diamond blade for cutting tile. On the other hand, if you are going to be cutting wood, you will want to use a different type of blade. This brings us to the first consideration, the type of material you plan to cut.
Blade Size
The first thing to realize about reciprocating saws is that not all reciprocating saws are created equal. There are five sizes of reciprocating saw blades, ranging in diameter from 3/4 inches to 4 inches. (One inch is about the size of the blade on a tape measure, and is the most common size.) The size of the saw you will use depends on the thickness of your fiberglass. If you are cutting 3/4 inch thick fiberglass, you will need a 3/4 inch blade. If you are using a 1-inch blade on 3/4 inch thick fiberglass, it will likely break. If you are cutting 1-inch thick fiberglass, you will need a 1-inch blade.
Blade Type
Most reciprocating saws are suitable for cutting metal, wood, and masonry. They can cut through concrete, brick, mortar, and stone. However, the use of this tool for fiberglass is not appropriate. This article is written to explain the reason why and introduce a way to cut fiberglass with a reciprocating saw.
Reciprocating saw blades are made of tungsten carbide. They are designed for cutting wood and metal. On the other hand, fiberglass is a composite material and is not cut by a reciprocating saw. Fiberglass is composed of many layers of fiberglass cloth which are bonded together with resin. The resin is hard and the saw blade is easily damaged by it.
Blade Length
The blade length used for a reciprocating saw depends on the work it will be used for. Some people prefer to have short blades for work like woodcutting and longer blades for metal cutting. When working with thick materials, the best choice is to go for longer blades. The length of the blade for a reciprocating saw typically ranges from 7 to 15 inches.
The length of the blade of the reciprocating saw is directly proportional to the thickness of the material to be cut. If you need to cut through thick material, then it is necessary to use a large blade. However, you need to ensure that the blade should not be a small one because it will be difficult for you to cut through the material with a small blade.
Thickness of Blade
The thickness of the blade for a reciprocating saw for fiberglass is important for your safe use. And the blade thickness is usually free to choose. The thickness of the blade is a factor in deciding which reciprocating saw to buy. If you are cutting a thick material like fiberglass with a thin blade, then you might not get clean results. The thick blade of a reciprocating saw can cut through thick materials like wood, metal, fiberglass, and other materials with ease.
Teeth-per-inch
The teeth-per-inch of a blade is a measurement used to determine how long a blade will last when cutting material. It is really a redundancy, as it is directly related to the blade thickness. It is relative to the material being cut and how much pressure is being applied. In general, the thicker the material being cut, the lower the TPI on the blade.
When shopping for a reciprocating saw, the blade is more important than the saw itself. If you want to cut through hard or soft materials, you need blades that are designed to do so. Also, if you want to cut in a straight line, you need blades that have a teeth-per-inch rating of no greater than 2.5. (When you see blades with higher tooth ratings, it simply means they are less effective at cutting.) And make sure the blade is the correct size for your saw.
