Hole Saw for Fiberglass: Your Buying Guide
Fiberglass is strong stuff. It is found in boats, cars, and bathtubs. You need a special tool to cut holes in it. That tool is called a hole saw. This guide helps you pick the best hole saw for fiberglass.

-
Tooth Design: Look for hole saws with teeth made to cut fiberglass. These teeth are usually made of special materials. They are designed to cut through fiberglass without chipping or breaking it.
-
Pilot Drill Bit: A pilot drill bit is in the center of the hole saw. This bit guides the saw. It keeps the hole saw from wandering. Make sure the pilot bit is sharp and durable.

Material: The hole saw itself should be made of strong stuff. High-speed steel (HSS) or carbide-tipped hole saws are good choices.
-
Cutting Depth: Check how deep the hole saw can cut. Make sure it is deep enough for your project.
