With a good quality hole saw and the correct drilling speed, you can make holes in steel, aluminum, wood, fibreglass, plastics and more! So for just about any application where you are looking to drill larger holes, a hole saw is most likely your best choice!
Industrial Hole Saw mandrels come in 2 basic categories; Small for hole saws from 9/16” through to 1-3/16” and Large for hole saws from 1-1/4” through to 6”. Make sure the shank size of the mandrel you are choosing with fit within the capacity of your drill chuck.
