A Hole saw is a type of cutting tool used for drilling holes in various materials such as wood, metal, plastic, and more. It consists of a cylindrical saw blade with teeth around its edge, attached to a drill bit and a pilot drill. The pilot drill guides the hole saw and helps to keep it centered on the surface being drilled.

Hole saws come in various sizes and can be used to create holes of different diameters. They are commonly used in construction, woodworking, plumbing, and electrical work.

Some hole saws have removable teeth or carbide tips, making them more durable and longer-lasting. They also have different tooth configurations and spacing, allowing for faster and smoother cuts.

When using a hole saw, it’s important to use the correct size and type of hole saw for the material being drilled, and to apply the appropriate amount of pressure and speed to achieve the desired results.

Hole saws come in various sizes and diameters, and the specific size chart may vary slightly depending on the manufacturer. However, below is a general size chart for hole saws:

• Small hole saws (up to 1 inch diameter): 3/4″, 7/8″, 1″, 1-1/8″, 1-1/4″, 1-3/8″, 1-1/2″
• Medium hole saws (1 to 3 inches diameter): 1-5/8″, 1-3/4″, 2″, 2-1/4″, 2-1/2″, 2-5/8″, 2-3/4″, 3″
• Large hole saws (3 to 6 inches diameter): 3-1/8″, 3-1/4″, 3-1/2″, 3-5/8″, 3-3/4″, 4″, 4-1/8″, 4-1/4″, 4-3/8″, 4-1/2″, 4-3/4″, 5″, 5-1/2″, 6″
