A hole saws is a cylindrical cutting cup that has a serrated edge used to cut hole through a large variety of materials. The serrated edge (cutting edge) is designed for cutting the hole, while the other end is designed to attach to a drill chuck or arbor that will drive it. There is a wide selection of hole saws available to the consumer, starting with low priced carbon steel and working their way up to specialized hole saws for specific applications. The most common and versatile hole saws, which provide greatest value, are bi-metal hole saws.

Good quality bi-metal hole saws will cut through soft materials like plastics and wood-based items, as well as harder materials like stainless steel. This is the reason why the majority of professionals choose bi-metal hole saws over other types. Another user benefit from bi-metal hole saws is the large number of holes they can cut before needing to replace them. These hole saws cut fast, smooth, reduce vibration, and lower your cost per cut.

Something you may want to think about when purchasing your hole saw is picking up an arbor (mandrel) that will allow you to connect your new hole saw to your drill chuck and keep the pilot bit in place. Some arbors include or allow for quick-change systems that will help you quickly change out your saws when cutting multiple sized holes in your materials. If your arbor allows for a pilot bit, remember the pilot bit will take the majority of the punishment while cutting. Look for a pilot bit that has a tapered web design allowing for a large amount of side pressure. These pilots are most times made with a thicker core and protect against side-load breakage.

When cutting with your hole saw, use caution. Surprisingly enough, these hole saws can be pretty hazardous if they bind up, or hit a nail while cutting. Both of these situations can cause the drill motor to turn violently in your hands, causing it to strain your wrist or hit you in the face. Predicting when you drill will bind is not possible, so take precautions to avoid injury. Always keep your drill straight, maintain a firm two-handed grip, and clamp small or loose pieces securely with a minimum of two clamps. Whenever possible brace your drills handle against your leg or hip, this will minimize the violent twist should your hole saw bind.
