The cutting diameter of a hole saw determines the size of the hole you can drill, making it one of the most crucial considerations when selecting the right tool. The best cutting diameter depends on the application—for example, smaller diameters (like 3/4" or 1-1/4") are ideal for wiring and plumbing, while larger diameters (such as 2-1/4" or 3-1/4") suit applications like door hardware or conduit installation. A wide range of diameters is available, from as small as 3/4" (Amana Tool 602-104, Makita 714004-A) to larger sizes like 3-1/4" (Amana Tool 602-166). Having access to a range of diameters, as found in the 16 Piece Bi-Metal Hole Saw Kit WE Preferred, provides versatility for various project requirements.
