Blades for a Sawzall are available for cutting many materials, including ___.

• A. Aluminum
• B. Fiberglass
• C. Wood
• D. Plastic

Answer: (B)

Blades are chosen to match what you’re cutting to get a clean edge and longer blade life. Fiberglass is a composite material that can splinter or fray if you use a blade not designed for it, so there are blades specifically made for cutting fiberglass and other composites. Those blades have tooth geometry or abrasive edge that minimize fiber pull-out and chipping, giving you a smoother cut. While wood, metal, and plastic blades exist as well, fiberglass stands out here as the material that truly relies on a blade designed for composites to achieve good results. Remember to wear eye protection and a dust mask when cutting fiberglass because of the fibers and dust produced.
