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.

FAQ:
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.
