best blade for cutting fiberglass

The outcome you get ineffectively cutting fiberglass is dependent on the type of saw blade used for the job. From the manufacturers’ desk, fiberglass is best cut with carbide-tipped blades. They also considered that depending on your project, the blade for cutting fiberglass should be purchased for specific saw types for effectiveness. With this understanding, this guide provides you with the best saw blade for the different types of saws and reviews of the best saw blade for cutting fiberglass.

Types of saw blades for cutting fiberglass

Sawzall Blade

The best Sawzall blade for cutting fiberglass should be picked based on its abrasive property because fiberglass also has abrasive characteristics in it. For Sawzall, a carbide-tipped or carbide-grit blade works best for cutting fiberglass.

Jigsaw blade

Using a blade for cutting metals is best for a jigsaw. The choice of metal blade is because fiberglass is tough and a Jigsaw gives the flexibility to cut curves in fiberglass more than any other type of saw.

Hacksaw blade

 Hacksaw blades are fine-toothed blades. They will work to cut fiberglass being fine-toothed but will need a lot more time to accomplish a piece of cutting task on fiberglass. This makes them not that suitable for use if there is a need to do so much cutting of fiberglass.

Circular Saw

Circular saws are like general-purpose saws. This makes them also suitable for cutting fiberglass. They are the ideal choice if a straight cut is required. In addition, they are often the choice when a fine-tooth blade is available.

Types of circular saw blades for cutting fiberglass

Circular carbide-tipped blades

These are blades that are brazened with small tips of carbide on the edges while the main body is a steel component. They are useful for making precision cuts on fiberglass materials.

Abrasive carbide-grit

These blades are made of fiberglass-reinforced silicon carbide abrasive material and are toothless. A blade of this type is capable of slicing hard materials including stones and tough substances like fiberglass.

The blades are not noisy when in use because of the through-cut vent implementation on them. It has the stabilizer vent (a laser cut vent) to curb noise and cut down vibration thereby cooling the blade and lowering the blade warp. The blade can expand owing to the heat expansion spaces in it to prevent heat build-up.

The Freud D1050X blades are designed to last long because of their durable carbide-made. The company’s proprietary shock-resistant TiCo Hi-Density Carbide composition shields the blade’s tough-built teeth lowers tear and wear and helps the blade retain its sharpness to about four times extra life.

1. What blade type is good at cutting fiberglass?

A Carbide-grit type of blade is suitable for cutting fiberglass including other hard materials like ceramic, cement board, and tiles.

2. What tool is the best at cutting fiberglass?

The Eastman chemical company recommends cutting fiberglass with a circular cutting blade. The blade is designed to crush and split materials containing glass fibers with ease. In addition, circular blades will cut fiber with less scattering than reciprocating blades.

3. Can you cut fiberglass with a grinder?

Yes. Using a metal cutting blade in an angle grinder is extremely fast but it is also has a very high chance of slipping and getting damaged during use.

4. Is cutting fiberglass dangerous?

It’s difficult to cut fiberglass without chipping, splintering, or tossing harmful fibers. While fiberglass is a safer alternative to asbestos, it still poses some health hazards. When fiberglass is disrupted, glass fibers form part of the debris and dust that flows in the air and collects on surfaces, much like asbestos.
