The arbor is usually made out of strong steel and alloys. This is because they need to be durable as their operation lasts through numerous saws.
Choosing between an attached or detachable arbor
Both of these arbors have their inherent benefits. You have to decide which benefits appeal most to you. The detachable arbor means that you can use the arbor with any hole saw. You do not need to get a new arbor for every hole saw you get.
On the other hand, an attached arbor eliminates the stress of detaching and re-attaching arbors when using a new hole saw.
