Metal hole saws are versatile tools with a range of applications. Here are some of the benefits of using a metal saw over a regular drill.

Versatility – Another benefit of using hole saws is the ability of a hole saw to cut a variety of hole sizes. There is a wide range of hole saw diameters in the market that are capable of cutting easily as compared to twisting a drill or spade to complete the same task.

What Does Arbored Hole Saw Mean?
Some hole saws are sold with detachable arbors, while others come with attached arbors. Other hole saws are sold without arbors, which means that you will have to buy an arbor separately.
Attached arbors in hole saws are usually welded or fixed to the saw’s blade and can’t be removed.
The benefit of this is that you will not need to dismantle the arbor and hole saw anytime you intend to change the size of your saw. Since attached arbors cannot be removed, saws with this can be said to be having an “integral shank.”
Unattached arbors are usually not fixed in the hole saw. They can be removed, and used on a variety of saw blades. Even though a detachable arbor can be removed, it can also have an integral shank.
Although a detachable arbor can be removed, it may also have an integral shank.

A shank refers to the shaft which runs in the middle of an arbor and the part attached to the drill bit.
In simple words, a drill that has an integral shank can only be suitable to use with a specific make, model, or range of hole saws. An Abor of one manufacturer might fail to fit in the saw blades of another manufacturer.
