Cutting a perfectly round hole in wood, plastic, metal, or even ceramic tile requires a specialized type of cutting tool—the hole saw. A hole saw is a ring-shaped saw blade measuring from less than 1 inch up to 4 inches in diameter and includes a bit that attaches to a standard cordless or corded drill. The blade features high-speed steel teeth that can cut perfectly round holes through materials ranging from metal to wood. A standard drill bit at the center of the hole saw serves as a pilot to center the blade over the material.

In this guide, we’ll explore the features to consider when shopping for a hole saw and discover some of the best hole saws on the market today for DIYers and pros alike.

What to Consider When Choosing the Best Hole Saw Kit

To choose the proper hole saw kit, it’s essential to consider such factors as the type of material with which the saw blades are made, the variety of available blade sizes, the number of drill bits included in the kit, the required power source for the hole saw, and the speed with which the hole saw can cut. Read on to learn more about these considerations when shopping for the best hole saw kit.

Blade Material

Hole saws are available in a variety of materials to suit different cutting needs. Most hole saws consist of high-speed steel, which cuts well while also resisting wear. Some hole saws are made of two metals: a carbon steel body—which boasts superior durability—and high-speed steel teeth.

Some high-end hole saws are constructed with advanced metals, such as carbon-steel alloy, which is harder than regular steel. Some saw blades go through a process called ice-hardening, which exposes the steel to subzero temperatures. This process helps to harden the steel, making it less susceptible to wear.

Additionally, some hole saws offer blades made with specialized materials. Hole saws with tungsten carbide tips can cut harder materials, such as thick steel, iron, pipe, and stainless steel. Hole saws with diamond-encrusted blades are suitable for cutting holes in hard materials that metal blades can’t cut through, including glass, ceramic, porcelain slate, tile, fiberglass, and limestone.

Blade Sizes

Hole saw kits include a variety of saw blade diameters to meet a multitude of needs. Sizes range from small ¾-inch-diameter blades up to large 4¾-inch-diameter saw blades. Hole saw blades typically include open slots on the side that allow for easy removal of the plug after cutting. Most kits provide at least 10 saw blades, along with a set of arbors and mandrels capable of holding the different blade sizes.

Drill Bits 

Hole saw kits also include a set of drill bits that function as pilot bits. These bits fit in the center of the round saw blade and serve as a guide that allows the operator to center the blade on the material. Many kits include multiple bits, so the user has backups should the bit wear down or break.

Power Source 

Since hole saw kits work with a power drill, they are either battery- or electric-powered. A battery-powered drill allows for convenient outdoor use where access to a power outlet is limited, while a corded drill provides less convenience but more power.

Since hole saws tend to require significantly more power than a standard drill bit, corded drills present the ideal means for powering these tools, as they produce more torque and higher RPMs than battery-powered drills, in addition to having access to an unlimited source of power.

Speed

Both the style of a saw blade and the material with which it’s made largely determine how quickly a hole saw can cut. Bimetal blades with high-speed steel are some of the quickest blades.

Blades designed with aggressive teeth angles and deep gullets that can remove more material with each rotation cut more quickly; however, they won’t make as smooth a cut as blades with more teeth and smaller gullets that take longer to cut.

Taking into consideration the above mentioned factors, this list of top picks below includes hole saw kits made with durable materials in a variety of categories and also covers a broad range of hole saw sizes. Read on to explore some of the best hole saw kits available today to ensure that the next hole is perfectly round.
